Science on the business of loving our dogs (and cats).

A fascinating article!

I have long subscribed to The Conversation and shared quite a few stories with you good people. But this recent one was a terrific report.

Read it yourself and I am sure you will agree with me.

New research suggests cat and dog ‘moms’ and ‘dads’ really are parenting their pets – here’s the evolutionary explanation why.

Have you noticed more cats riding in strollers lately? Or bumper stickers that read, “I love my granddogs”? You’re not imagining it. More people are investing serious time, money and attention in their pets.

It looks an awful lot like parenting, but of pets, not people.

Can this kind of caregiving toward animals really be considered parenting? Or is something else going on here?

I’m an anthropologist who studies human-animal interactions, a field known as anthrozoology. I want to better understand the behavior of pet parenting by people from the perspective of evolutionary science. After all, cultural norms and evolutionary biology both suggest people should focus on raising their own children, not animals of a completely different species.

More child-free people, more pet parents

The current moment is unique in human history. Many societies, including the U.S., are experiencing major changes in how people live, work and socialize. Fertility rates are low, and people have more flexibility in how they choose to live their lives. These factors can lead people to further their education and value defining oneself as an individual over family obligations. With basics taken care of, people can focus on higher order psychological needs like feelings of achievement and a sense of purpose.

The scene is set for people to actively choose to focus on pets instead of children.

In earlier research, I interviewed 28 self-identified child-free pet owners to better understand how they relate to their animals. These individuals pointedly shared that they had actively chosen cats and dogs instead of children. In many cases, their use of parent-child relational terms – calling themselves a pet’s “mom” for instance – was simply shorthand.

They emphasized fulfilling the species-specific needs of their dogs and cats. For example, they might fulfill the animal’s need to forage by feeding meals using a food puzzle, while most children are fed at the table. These pet owners acknowledged differences in the nutrition, socialization and learning needs of animals versus children. They were not unthinkingly replacing human children with “fur babies” by treating them like small, furry humans.

Other researchers find similar connections, showing that child-free pet owners perceive their companions as emotional, thinking individuals. This way of understanding the mind of the animal helps lead to the development of a parent identity toward companion animals. In other cases, uncertain individuals find their need to nurture sufficiently fulfilled by caring for pets, cementing their fertility decisions to remain child-free.

Nurturing others is part of being human

Yet, these findings still do not answer this question: Are people who choose pets over children truly parenting their pets? To answer, I turned to the evolution of parenting and caregiving.

Evolutionary anthropologist Sarah Hardy wrote in 2009 that humans are cooperative breeders. This means it is literally in our DNA and our ancestral history to help care for offspring who are not our own. Anthropologists and biologists call this trait alloparenting. It is an evolutionary adaptation that helped human beings who cooperatively raised children survive. For early humans, this ancient environment was likely made up of small, foraging societies in which some people exchanged child care for food and other resources.

I propose that it is this evolutionary history that explains pet parenting. If people evolved to alloparent, and our environment is now making caring for children more difficult or less appealing to some, it makes sense for people to alloparent other species entering their homes. Alloparenting companion animals can offer a way to fulfill the evolved need to nurture while reducing the investment of time, money and emotional energy compared to raising children.

Untangling differences in caring for pets

To further understand this phenomenon of child-free adults parenting pets, I launched an online survey via social media, seeking responses from U.S.-based dog and cat owners over the age of 18. The survey included questions about attachment and caregiving behaviors using the Lexington Attachment to Pets Scale. It also asked a series of questions I developed to probe specific human caretaking behaviors oriented toward pets – things like feeding, bathing and training – as well as how much autonomy companion animals had in the home.

The final sample of 917 respondents included 620 parents, 254 nonparents and 43 people who were undecided or did not answer. Most of the respondents were also married or in a domestic partnership for over one year (57%), between the ages of 25 and 60 (72%) and had at least a bachelor’s degree (77%). They were also mostly women (85%) and heterosexual (85%), a common situation in human-animal interactions research.

Both parents and nonparents reported high amounts of training and play with their pets. This finding makes sense given that all pet owners need to help their dogs and cats learn how to navigate a human world. Survey respondents reported socializing, training and enrichment, including play, for their animals.

Nonparents were more likely to be the one providing general care for the animal. This finding also makes sense since parents often adopt or purchase companion animals as a way to help their children learn responsibility and to care for others. Child-free animal owners invest time, money and emotional energy directly in their pets.

Nonparents reported higher rates of general attachment to their animals. They more frequently viewed their pets as individuals. Nonparents were also more likely to use family terms such as “parent,” “child,” “kids” and “guardians” when referring to their relationships with their pet.

It is this difference, combined with the evidence from my earlier research that these individuals address the species-specific needs of the dogs and cats in their care, that suggests pet parenting is, truly, parenting pets. Though the details may look quite different – attending training classes instead of school functions, or providing smell walks for dogs instead of coloring books for children – both practices fulfill the same evolved function. Whether child or pet, people are meeting the same evolved need to care for, teach and love a sentient other.

My colleagues and I continue to collect data from all over the world about how people live with animals. For now, this study provides evidence that, perhaps rather than being evolved to parent, humans are evolved to nurture. And as a result, who and when we parent is much more flexible than you might initially believe.

Shelly does a fabulous job of looking more closely at the science and it is a science that has a very wide appeal. For in the UK, according to the RSPCA, “In the UK, it’s estimated that 12 million (44 percent of) households have pets with around 51 million pets owned.“

Here in America The Washington Post reported that: “Google the U.S. pet population, and you’re quickly confronted with two oft-cited, and contradictory, sources. The American Pet Products Association (APPA) found that 68 percent of U.S. households owned some sort of pet in 2016 — “equal to the highest level ever reported,” it gushed in the executive summary. Among those pets were about 90 million dogs and 94 million cats, the group said.“

That is just two countries. The worldwide population of dogs and cats must be gigantic.

The smell of COVID-19!

That is to a dog!

It was only a matter of time before the dog’s supreme sense of smell came to the aid of COVID-19 hunters!

A dog has a sense of smell that is 10,000 to 100,000 times more acute than that of a human.

But back to COVID-19.

Here’s an article from the Smithsonian.

Dogs Are Being Trained to Sniff Out COVID-19

Researchers are attempting to teach eight dogs to detect the pandemic, which could help quickly screen large numbers of people in public places

Dogs are being enlisted in the fight against the novel coronavirus. Researchers at the University of Pennsylvania are testing a pack of eight Labrador retrievers to find out if their sensitive snouts can detect the pandemic virus by scent, Karin Brulliard reports for the Washington Post.
Humans have trained our canine friends’ finely tuned noses to sniff out other deadly diseases, including malaria, diabetes, some cancers and Parkinson’s disease, reported Ian Tucker for the Guardian in 2018. Other research has shown that viruses give off a particular smell, Cynthia Otto, director of the Working Dog Center at UPenn’s School of Veterinary Medicine, tells the Post.

If the dogs’ 300 million scent receptors can be trained to smell the novel coronavirus they could eventually be used in public places such as airports, businesses or hospitals to quickly and easily screen large numbers of people. Because this diagnosis by dog would depend on the smell given off by people infected with COVID-19 it should have no problem picking out asymptomatic carriers.

The yellow, black and chocolate labs will be trained for three weeks using a process called odor imprinting. Miss M., Poncho and six other dogs will be exposed to COVID-19 positive saliva or urine collected from hospitals and then rewarded with food when they pick out the correct samples, according to a statement from UPenn. When the dogs have the scent, they’ll be tested to see if they can pick out COVID-19 positive people.

“We don’t know that this will be the odor of the virus, per se, or the response to the virus, or a combination,” Otto, who is leading the project, tells the Post. “But the dogs don’t care what the odor is. … What they learn is that there’s something different about this sample than there is about that sample.”

Dogs are also being trained for this purpose in the United Kingdom by the charity Medical Detection Dogs in collaboration with Durham University and the London School of Hygiene and Tropical Medicine, reports the BBC.

“This would help prevent the re-emergence of the disease after we have brought the present epidemic under control,” Steve Lindsay, public health entomologist at Durham University, tells the BBC.

The U.K. trial expects to start collecting COVID-19 positive samples in the coming weeks and will train its dogs shortly thereafter, per the Post. If the trial is successful the group aims to distribute six dogs to be used for screening in U.K. airports.

“Each individual dog can screen up to 250 people per hour,” James Logan, epidemiologist at Durham University and collaborator on the project, tells the Post. “We are simultaneously working on a model to scale it up so it can be deployed in other countries at ports of entry, including airports.”

Otto tells the Post that the trial could inspire an electronic sensor that could detect COVID-19 which might be able to rapidly test thousands of people. But if the dogs’ olfactory prowess can’t be replicated, then the ability to scale up could be limited by another issue: the U.S.’s shortage of detection dogs.

ooOOoo

The list of fabulous skills that dogs have and their ability to help us humans out is practically endless.

To be more to the point, if dogs really can make a difference in determining who has got COVID-19, especially at airports, then this is a step to eventually returning to a more open and normal lifestyle.

May it happen!

I would like to close by returning to that NOVA article and republishing the following:

Put another way, dogs can detect some odors in parts per trillion. What does that mean in terms we might understand? Well, in her book Inside of a Dog, Alexandra Horowitz, a dog-cognition researcher at Barnard College, writes that while we might notice if our coffee has had a teaspoon of sugar added to it, a dog could detect a teaspoon of sugar in a million gallons of water, or two Olympic-sized pools worth. Another dog scientist likened their ability to catching a whiff of one rotten apple in two million barrels.

Incredible!

The early beginnings.

Science has maybe found a clue to the ancestor of the dog and the wolf.

For an animal that means so much to us humans, the origins of the dog are still uncertain. Indeed, as this interesting article shows, the origins of the wolf are uncertain.

Was This 18,000-Year-Old Puppy Frozen in Siberian Permafrost the Ancestor of Wolves, Dogs or Both?

Meet Dogor, an 18,000-year-old pup unearthed in Siberian permafrost whose name means “friend” in the Yakut language. The remains of the prehistoric pup are puzzling researchers because genetic testing shows it’s not a wolf or a dog, meaning it could be an elusive ancestor of both.

Locals found the remains in the summer of 2018 in a frozen lump of ground near the Indigirka River, according to the North-Eastern Federal University in Yakutsk. Parts of the animal are incredibly well-preserved, including its head, nose, whiskers, eyelashes and mouth, revealing that it still had its milk teeth when it died. Researchers suggest the animal was just two months old when it passed, though they do not know the cause of death.

The pup is so well-preserved that researchers at the Centre for Palaeogenetics in Sweden were able to sequence the animal’s DNA using a piece of rib bone. The results found that Dogor was male, but even after two rounds of analysis the team could not determine whether he was a dog or a wolf.

“It’s normally relatively easy to tell the difference between the two,” David Stanton, a Centre for Palaeogenetics research fellow, tells Amy Woodyatt at CNN. “We have a lot of data from it already, and with that amount of data, you’d expect to tell if it was one or the other. The fact that we can’t might suggest that it’s from a population that was ancestral to both—to dogs and wolves.”

The find is exciting, regardless of whether Dogor turns out to be a common canine ancestor, an early dog, or an early wolf. Hannah Knowles at The Washington Post reports that Dogor comes from an interesting time in canine evolution, when wolf species were dying out and early dogs were beginning to emerge.

“As you go back in time, as you get closer to the point that dogs and wolves converge, [it becomes] harder to tell between the two,” Stanton tells Knowles.

The history of just how and when dogs split from wolves is unresolved. There’s a general agreement among scientists that modern gray wolves and dogs split from a common ancestor 15,000 to 40,000 years ago, explains Brian Handwerk previously for Smithsonian.com. How dogs became dogs, however, is contested. Some research suggests that dogs were domesticated by humans once, while other studies have found dogs were domesticated multiple times. Exactly where in the world wild canines became man’s best friend is also disputed. The origin of the human-animal bond has been traced to Mongolia, China and Europe.

Scientists disagree about how dogs ended up paired with people, too. Some suspect humans captured wolf pups and actively domesticated them. Others suggest that a strain of “friendly,” less aggressive wolves more or less domesticated themselves by hanging out near humans, gaining access to their leftover food.

Dorgor’s DNA could help unravel these mysteries. The team plans to do a third round of DNA testing that may help definitively place Dogor in the canine family tree, report Daria Litvinova and Roman Kutuko at the Associated Press.

This is incredibly interesting, don’t you think?

Hopefully I will hear of that third round of DNA testing and, if so, will most definitely share it with you.

It’s not all hugs and smiles.

August 20

RIO DE JANEIRO — High above this Brazilian city, in a jungle blanketing a mountain, the turtles were out, and the scene was hopeful.

Scientists were reintroducing 15 mud-caked tortoises to this urban forest where they had once been plentiful. Children were running around. People were oohing and aahing. A stern-looking security guard appeared to briefly smile.

But not government biologist Katyucha Silva. She was thinking about dogs.

What would they do to these turtles? What were they doing to Brazil?

It’s a question more researchers are beginning to ask in a country where there are more dogs than children — and where dogs are quickly becoming the most destructive predator. They’re invading nature preserves and national parks. They’re forming packs, some 15 dogs strong, and are hunting wild prey. They’ve muscled out native predators such as foxes and big cats in nature preserves, outnumbering pumas 25 to 1 and ocelots 85 to 1.

Every year, they become still more plentiful, spreading diseases, disrupting natural environments, goosing scientists who set up elaborate camera systems to photograph wild animals, only to come away with pictures of curious canines.

“It’s a difficult thing for people to hear,” said Isadora Lessa, a Rio de Janeiro biologist who wrote her doctoral dissertation on domestic dogs causing environmental mayhem. “They love dogs too much.”

How the dog became one of the world’s most harmful invasive mammalian predators is as much a global story as a Brazilian one. Over the last century, as the human population exploded, so did the dog population, growing to an estimated 1 billion.

That has been great for people — and even better for dogs — but less so for nature, according to a growing body of academic research implicating canines, particularly the free-roaming ones, in environmental destruction.

“The global impacts of domestic dogs on wildlife are grossly underestimated,” researchers concluded in a 2017 study published in the journal Biological Conservation. The researchers, based in Australia, convicted dogs in the extinction of 11 species and declared them the third-most-damaging mammal, behind only cats and rodents.

The International Union for Conservation of Nature maintains a list of animals whose numbers dogs are culling. There are 191, and more than half are classified as either endangered or vulnerable. They range from lowly iguanas to the famed Tasmanian devil, from doves to monkeys, a diversity of animals with nothing in common beyond the fact that dogs enjoy killing them. In New Zealand, the organization reported, a single German shepherd once did in as many as 500 kiwis — and that was the conservative estimate.

“Unfortunately, we have a big problem,” said Piero Genovesi, chair of the agency’s invasive species unit. “There is a growing number of dogs.”

People all over the world are — begrudgingly — beginning to take note.

In Chile, stray dogs were the top concern among city dwellers surveyed this year, topping deteriorating sidewalks and theft. In New Zealand, some communities moved last year to restrict the movement of dogs in a gambit to save little blue penguins. In India, farmers are complaining about stray dogs killing their livestock, just as other predators once had.

And in Brazil, atop a mountain outside of Rio de Janeiro, 15 tortoises were nestling into the forest floor, oblivious to the danger of the forest’s leading predator.

‘A complex problem’

Brazil is home to an estimated 52 million dogs, according to the most recent government statistics — more than anywhere in Latin America — but their lives vary widely. In a nation defined by inequality, where the rich fly in helicopters over the poor in the favelas below, the dog has become one more way of understanding the divide.

In wealthy cities, the dog is everywhere, strolling through fancy shopping malls, sitting in the laps of restaurant patrons, even riding paddle boards out on the surf. Some people wheel their dogs around in little strollers.

“The dog brings to Brazilians some things that Brazilians appreciate in themselves,” said Alexandre Rossi, a television personality more commonly known as Dr. Pet. “To be friendly, to want to socialize with everyone . . . and be there and be close to your family. These are perceived as very good Brazilian qualities.”

On the streets of trendy Ipanema one recent afternoon, few people could believe that a dog — or at least their dog — could be much of predator.

“The dog is a friend!” sputtered Philipe Soares, the furball Bobby at his feet. “No, I’ve never thought of him that way.”

“Difficult to imagine,” said Carlos Alberto Vicente, peering down at his own pooch.

“In her case,” said Flavio Vilela, a shirtless man striding through a park with a small mutt named Nicoli, “they’d hunt her.”

The problem, researchers say, isn’t these dogs, who lead the coddled lives of European or American pets.

The problem is the dogs in poorer and more rural communities, where the life of the dog is more frequently the life of hunger. They prowl the streets day and night with neither a collar nor an owner, looking for food wherever it can be found — in trash heaps, alongside roads, and in forests and fields, where they form packs to hunt and kill.

“It’s a very complex problem,” said Silva, the government biologist.

A stunning discovery

Ana Maria Paschoal, a researcher at the Federal University of Minas Gerais, remembers when she first started thinking about the dog differently. She was out in the Atlantic Forest in Southeast Brazil around a decade ago when she noticed there were an awful lot of them.

She wondered: How many dogs are using the protected areas? Are these feral or domestic dogs? Is their presence changing the occurrence of wild species?

So she set up cameras across 2,400 acres of forest to find out. What she discovered, published in 2012 in the scientific journal Mammalia, stunned her.

The dog wasn’t just the most-recorded carnivore; it was the most-recorded animal of the 17 mammals the cameras captured.

“The presence of the domestic dog is a threat,” Paschoal and her co-authors concluded.

The research, subsequently confirmed in a larger survey, laid the groundwork for a growing field of study here. One researcher linked Brazil’s dogs to the spread of diseases. Another accused the dogs in the National Park of Brasilia, where they hunted in massive packs, of scaring off natural predators. It was found that the closer humans lived to a nature preserve, the more likely dogs had penetrated it.

But perhaps most striking? The dogs were neither feral nor domestic — but somewhere in between.

“All the dogs we detected had an ‘owner’ or a person that the animal has a bond with,” Paschoal said. “The species population increases following human populations, exacerbating their potential impact on wildlife.”

It was something Fernando Fernandez, an ecology professor at the Federal University of Rio de Janeiro, learned the hard way. For the last decade, he has been reintroducing native animals to the Tijuca forest, one of the world’s largest urban woodlands, which spills across Rio de Janeiro’s mountains.

First came the agouti, a squirrel-like rodent. Then followed a problem: “Dogs.”

They started killing the agouti, and not for food. It was just for fun.

Fernandez and Silva wanted to learn more. They set up cameras and discovered dozens of dogs in the forest. They estimated more than 100 dogs were in the park — not residents, it turned out, so much as frequent visitors, tracking in from nearby favelas.

“These are people who are very poor,” said Silva, who has six dogs at home. “They don’t have money to build walls. . . . When the owners leave for work, the dog leaves, too, and only returns when the owner comes back to the house from work.”

The owners often have no idea what their dogs are up to. Even if they were told, Rob Young said, they almost certainly wouldn’t believe it.

Young, chairman of wildlife conservation at the University of Salford in Britain, witnessed the psychology at work after seeing dogs kill flightless birds in the state of Minas Gerais.

“We’d do interviews with the farmers: ‘Have you seen these dogs?’

“And they’d say, ‘Yeah, but my dogs aren’t the problem; it’s my neighbor’s dogs.’

“Every farmer would say the same thing.”

These factors — inability to see aggression in dogs, in­trac­table inequality, the rapid expansion of humanity — left Silva feeling apprehensive as she watched the tortoises being reintroduced into the Tijuca forest.

In the long term, she didn’t know how the problem of dogs laying waste to the world’s environments would realistically improve.

And in the short term: Could dogs kill these tortoises, just as they’d dispatched a few agouti?

“Yes,” she said. “They could.”

Silva worries that tortoises reintroduced in the park could fall prey to dogs. (Terrence McCoy/The Washington Post)

It’s a tough read and there doesn’t appear to be a solution, not in the short-term at least.

As was reported in the article it is as much a global problem with something of the order of a billion dogs roaming the planet.

Does anyone have any ideas for a solution?

A Perfectly Preserved 32,000-Year-Old Wolf Head Was Found in Siberian Permafrost

Given the head’s state of preservation, researchers are hopeful that they can extract viable DNA and use it to sequence the wolf’s genome.

Last summer, a mammoth tusk hunter exploring the shores of the Tirekhtyak River in Siberia’s Yakutia region unearthed the fully intact head of a prehistoric wolf. Preserved by the region’s permafrost, or permanently frozen ground, for some 32,000 years, the specimen is the first partial carcass of an adult Pleistocene steppe wolf—an extinct lineage distinct from modern wolves—ever found.

The discovery, first reported by the Siberian Times, is poised to help researchers better understand how steppe wolves compared with their contemporary counterparts, as well as why the species eventually died out.

As Marisa Iati writes for the Washington Post, the wolf in question was fully grown, likely aged 2 to 4 years old, at the time of its death. Although photographs of the severed head, still boasting clumps of fur, fangs and a well-preserved snout, place its size at 15.7 inches long—the modern gray wolf’s head, in comparison, measures 9.1 to 11 inches—Love Dalén, an evolutionary geneticist at the Swedish Museum of Natural History who was filming a documentary in Siberia when the tusk hunter arrived on the scene with the head in tow, says that media reports touting the find as a “giant wolf” are inaccurate.

“It is not that much bigger than a modern wolf if you discount the frozen clump of permafrost stuck to where the neck would [normally] have been,” Dalén explains to Smithsonian.com.

According to CNN, a Russian team led by Albert Protopopov of the Republic of Sakha’s Academy of Sciences is currently building a digital model of the animal’s brain and the interior of its skull.

David Stanton, a researcher at the Swedish Museum of Natural History who is leading genetic analysis of the remains, tells Smithsonian.com that given the head’s state of preservation, he and his colleagues are hopeful that they can extract viable DNA and use it to sequence the wolf’s genome. This work, expected to last at least another year, will eventually be published in a peer-reviewed scientific journal.

For now, it remains unclear exactly how the wolf’s head became separated from the rest of its body. Speaking with Smithsonian.com, Tori Herridge, an evolutionary biologist at London’s Natural History Museum who was part of the team filming in Siberia at the time of the discovery, says that a colleague, Dan Fisher of the University of Michigan, thinks scans of the animal’s head may reveal evidence of it being deliberately severed by humans—perhaps “contemporaneously with the wolf dying.” If so, Herridge notes, the find would offer “a unique example of human interaction with carnivores.” Still, she concludes in a post on Twitter, “I am reserving judgment until more investigation [is] done.”

Dalén echoes Herridge’s hesitancy, saying that he has “seen no evidence convincing” him that humans cut off the head. After all, it’s not uncommon to find partial sets of remains in the Siberian permafrost. If an animal was only partially buried and subsequently frozen, for example, the rest of its body could have decomposed or been eaten by scavengers. Alternatively, it’s possible that shifts within the permafrost over thousands of years led the carcass to break into multiple pieces.

According to Stanton, steppe wolves were “probably slightly larger and more robust than modern wolves.” The animals had a strong, wide jaw equipped for hunting large herbivores such as woolly mammoths and rhinos, and as Stanton tells USA Today’s N’dea Yancey-Bragg, went extinct between 20,000 to 30,000 years ago, or roughly the time when modern wolves first arrived on the scene. If the researchers successfully extract DNA from the wolf’s head, they will attempt to use it to determine whether the ancient wolves mated with modern ones, how inbred the older species was, and if the lineage had—or lacked—any genetic adaptations that contributed to its demise.

To date, the Siberian permafrost has yielded an array of well-preserved prehistoric creatures: among others, a 42,000-year-old foal, a cave lion cub, an “exquisite ice bird complete with feathers,” as Herridge notes, and “even a delicate Ice Age moth.” According to Dalén, these finds can largely be attributed to a surge in mammoth tusk hunting and increased melting of permafrost linked with global warming.

Speaking with Smithsonian.com, Stanton concludes, “The warming climate … means that more and more of these specimens are likely to be found in the future.”

At the same time, he points out, “It is also likely that many of [them] will thaw out and decompose (and therefore be lost) before anyone can find … and study them.”

ooOOoo

It’s an ill wind that blows no-one any good. That saying comes to mind when I read about the warming climate and more specimens being found.

Fascinating!

New Study Has a Bone to Pick With Dog Domestication Findings

Contrary to past research, a new DNA study suggests fido was only tamed once

One wave of domestication or two? The debate rages on. (Dageldog/iStock)

Though dogs are humanity’s oldest and most consistent animal friend, scientists have long struggled to figure out just how Canis familiaris came to be. Though researchers agree dogs are descended from wild wolves, they aren’t sure when and where domestication occurred. And as Tina Hesman Saey at Science News reports, a new study has revived the debate, suggesting that dogs were domesticated one time between 20,000 and 40,000 years ago.

Dog domestication has gotten a lot of attention in recent years. In 2016, researchers looked at the mitochondrial DNA of modern and ancient dog species, determining that dogs come from two different wolf populations, one found in Europe and one found in Asia. That means that wolves would have been domesticated in two different places, with the two lineages eventually mixing in modern dogs.

But this latest research contradicts the double-domestication hypothesis. According to Ben Guarino at the Washington Post, researchers looked at the well-preserved DNA of two ancient dogs found in Germany, one 7,000 years old and one 4,700 years old, as well as the complete genomes of 100 modern dogs and snippets of DNA from 5,600 other wolves and dogs.

They traced the rate of mutations in the over time in the dog genomes. This technique, which creates a “molecular clock,” indicates that dogs diverged from wolves 36,900 years ago to 41,500 years ago in a single domestication event. But they can’t determine exactly where the split occurred. About 20,000 years later, the molecular clock indicates dogs split into European and Asian groups. They published their results in the journal Nature Communications

Not everyone is convinced by the study. Greger Larson, Oxford evolutionary biologist and author of the earlier domestication study, tells Guarino that the latest research does not explain the “ridiculously deep split” between the genetics of ancient European and Asian dogs. He also points out that while ancient dog bones have been found in far eastern Asia and western Europe, the middle of Eurasia seems to be empty of dog bones, suggesting that there were two ancient populations, separated by vast distances.

Krishna Veeramah, a palaeogeneticist at Stony Brook University and author of the new study says he doesn’t anticipate that the paper will put the issue to rest. “More ancient dog DNA from genomes will ultimately solve the problem,” he tells Rachael Lallensack at Nature. Researchers are hoping to find more geographically diverse DNA from dogs as well as samples from different time periods.

Whether it happened once or twice, how and why did domestication occur?

As Veeramah​ tells Helen Briggs at the BBC that it’s likely dogs evolved from wolves that began hanging around human camps, scavenging their scraps. ”Those wolves that were tamer and less aggressive would have been more successful at this,” he says. “While the humans did not initially gain any kind of benefit from this process, over time they would have developed some kind of symbiotic relationship with these animals, eventually evolving into the dogs we see today.”

One early benefit of domesticated dogs may have been that they could help transport meat from carcasses or hunt dangerous game like cave bears and cave lions, Saey writes in an earlier Science News article.

For now, however, exactly when and where Fido first approached humans will remain a mastiff question.

ooOOoo

For my money the origins of the domestic dog are as Krishna Veeramah puts it: ”Those wolves that were tamer and less aggressive would have been more successful at this,” he says. “While the humans did not initially gain any kind of benefit from this process, over time they would have developed some kind of symbiotic relationship with these animals, eventually evolving into the dogs we see today.”

Pure, unconditional love.

Giving from the heart; in this case a dog’s heart.

As many readers know we have nine dogs here at home, divided into the ‘kitchen’ group (Paloma, Casey and Ruby) and the ‘bedroom’ group (Pharaoh, Brandy, Cleo, Sweeny, Pedy and Oliver). Inevitably the latter group are closer to us because they share the bulk of the home with Jeannie and me, and sleep in our bedroom. Don’t get me wrong, I am not saying that the kitchen group are any less affectionate than the bedroom group it’s just that, for me especially, I am able to be emotionally and physically closer to our bedroom group because for most of the hours of each day they are close to me.

Brandy, Cleo and Oliver seem to be incredibly sensitive to Jeannie’s and my feelings. If something makes me cry then one of them will be next to me in seconds. When Jeannie and I hug, Oliver will stand on his rear legs, place his front legs on our bodies above our waists and act as if he is hugging us. Even the mention of the word “out” has Cleo running to the front door.

So many more examples but you get the drift!

Last Friday The Washington Post published a heart-breaking story. It concerned a young man, just 33-years-old, who was dying from a brain hemorrhage. Here’s an extract from that story:

Ryan Thomas Jessen had gone to the hospital for what he thought was a migraine, but it turned out to be a brain hemorrhage, his sister, Michelle Jessen, wrote on Facebook earlier this month.

The hemorrhage, which doctors believe may have been brought on by high blood pressure, would prove fatal.

But before Jessen died, the 33-year-old Californian’s family wanted to let his dog, Mollie, see him one last time.

Michelle Jessen filmed that last visit by Mollie and, as one might expect, the video has been shared right across the world.

So very often words come so difficult when one wants to reflect on what we have just watched.

Which is why I’m allowing Jimmy Stewart to make it easier.

He never came to me when I would call

Unless I had a tennis ball,

Or he felt like it,

But mostly he didn’t come at all.

When he was young

He never learned to heel

Or sit or stay,

He did things his way.

Discipline was not his bag

But when you were with him things sure didn’t drag.

He’d dig up a rosebush just to spite me,

And when I’d grab him, he’d turn and bite me.

He bit lots of folks from day to day,

The delivery boy was his favorite prey.

The gas man wouldn’t read our meter,

He said we owned a real man-eater.

He set the house on fire

But the story’s long to tell.

Suffice it to say that he survived

And the house survived as well.

On the evening walks, and Gloria took him,

He was always first out the door.

The Old One and I brought up the rear

Because our bones were sore.

He would charge up the street with Mom hanging on,

What a beautiful pair they were!

And if it was still light and the tourists were out,

They created a bit of a stir.

But every once in a while, he would stop in his tracks

And with a frown on his face look around.

It was just to make sure that the Old One was there

And would follow him where he was bound.

We are early-to-bedders at our house — I guess I’m the first to retire.

And as I’d leave the room he’d look at me

And get up from his place by the fire.

He knew where the tennis balls were upstairs,

And I’d give him one for a while.

He would push it under the bed with his nose

And I’d fish it out with a smile.

And before very long He’d tire of the ball

And be asleep in his corner In no time at all.

And there were nights when I’d feel him Climb upon our bed

And lie between us,

And I’d pat his head.

And there were nights when I’d feel this stare

And I’d wake up and he’d be sitting there

And I reach out my hand and stroke his hair.

And sometimes I’d feel him sigh and I think I know the reason why.

He would wake up at night

And he would have this fear

Of the dark, of life, of lots of things,

And he’d be glad to have me near.

And now he’s dead.

And there are nights when I think I feel him

Climb upon our bed and lie between us,

And I pat his head.

And there are nights when I think I feel that stare

And I reach out my hand to stroke his hair,

But he’s not there.

Oh, how I wish that wasn’t so,

I’ll always love a dog named Beau.

There is no love without pain,

But to have lived without the love of a dog in one’s life would be not to have lived at all.

Our dear, dear dogs!

Our healing dogs!

Is it me or is the world becoming crazier each new day!

What with the ‘Remain/Leave’ EU referendum coming up in my old country and Presidential politics in my new country it seems these days as though the need for healing is growing in leaps and bounds. Thank goodness for being able to hug a dog or two (and Jean) to be reminded of what matters most of all.

I was reminded of the incredible healing power of our dogs in a recent article published by author Deborah Taylor-French. That will be republished tomorrow, with Deborah’s kind permission. However, I wanted to make this message last for more than a single post and to achieve that I’m republishing a guest post that appeared in this place towards the end of last year.

But first my introduction to that guest post.

Forget about the big world out there, be loved by our dogs.

Monday’s post about the precariousness of man’s future on this planet if we don’t prevent the melting of the Antarctic ice sheet was a bit gloomy, however true it might be. The gloom continued with yesterday’s post about the VW scandal illustrating the “unethical culture endemic in business”.

So what a nice change to think about the way that our pets keep us bright, cheerful and healthy.

All of which is my way of introducing a guest post from Vee Cecil. Now I am fairly cautious about guest posts from those who want to promote their businesses, for obvious reasons. But Vee’s essay is so lovely that it truly deserves to be shared.

Firstly, here is the email that Vee sent me back in August,

Hi!

In the U.S., 91 percent of pet owners say they consider their pet to be a member of the family. And for good reason! Our pets are constant sources of comfort and companionship.

What many pet owners may not realize is how great their furry family members are for their physical and mental health. For example, studies have shown that pet owners have lower blood pressure than people who don’t have pets and that being around pets also makes us “less anxious and less stressed.” And that’s just the beginning. There are many other wonderful health benefits that result from owning a pet.

May I write an article for learningfromdogs.com on this topic? The article will be approximately 500 words, unique to your site, and complete with resources.

Please let me know – I am always looking to spread the word about how we can be healthier and happier and having a pet is a great way to achieve both!

Best,
Vee

Here then is that article.

Feeling Under the Weather? Learn More About the Amazing Healing Powers of Pets

HappyTailsAsk any dog owner and you’ll find out just how remarkable a dog can be. They can turn a terrible day into an amazing one with one lick of the face or wag of the tail. But more and more studies are showing that our four-legged friends might be even more awesome than we previously thought.

As The Washington Post explains, research is showing that being around dogs can help us feel better and less stressed, while also improving our physical health. For example, the article cites studies which found that our pets can lead to “lower blood pressure, lower resting heart rates and less risk of hypertension.”

And that’s not all. Here are four other health issues and how dogs help their human companions:

Cancer. As this CBSNews.com article explains, a recent study at Mount Sinai Beth Israel found that therapy dogs had a very positive impact on patients receiving chemo therapy. The patients showed improvements in “emotional well-being and quality of life.” The director of the program that provided the therapy dogs also noted that patients felt less stressed and anxious. The article notes that this was a ground-breaking study as the impact of therapy dogs on cancer patients hadn’t been examined before.

Alzheimer’s Disease. Therapy dogs are also proving to be extremely helpful for patients with Alzheimer’s. In this article, a man with early on-set Alzheimer’s explains how his therapy dog helps him with daily tasks. Through the help of his therapy dog, the man says his stress and anxiety levels have significantly reduced.

Surgery recovery. Chances are if you were recovering from a painful surgery you wouldn’t turn down a snuggle from a pet. But, as The Telegraph shows, researchers have found that pets can do more than just provide you with a little tender loving care. A study led by a researcher from Loyola University found that pet therapy can reduce the amount of pain patients experience after surgery. In fact, according to the article, the patients in the study, who had had joint replacement surgery, “needed 50 per cent less pain medication if they used pet therapy.”

Diabetes. And perhaps most remarkable of all is what therapy dogs can be trained to do for diabetics. In this case, dogs put their acute sense of smell to good use. As this article explains, dogs exhibiting a better-than-average sense of smell can be trained to help diabetics. Once trained these dogs use their sense of smell to detect signs of hypoglycemia and low blood sugar (based on their human companion’s breath). They’re also trained to get a sugary food for their diabetic, get help if the person goes into diabetic shock, and more.

As more research is conducted to see the benefits of not only service dogs, but pets too, it will be interesting to see how dogs are woven into more medical treatments. They are truly amazing creatures, who can help us mind, body, and soul.

The book! Part Five: Play

So what can we learn from dogs from the way that they play?

It’s a fair question yet one where it might be perfectly reasonable to wonder if we humans have anything to learn from the playing of dogs. The answers may surprise.

But first, let’s examine what is known about the playing of dogs.

Marc Bekoff, Professor Emeritus of Ecology and Evolutionary Biology at the University of Colorado, Boulder, is referred to extensively in The Washington Post; May 19th, 2014, in an article written by David Grimm, author of a new book: Citizen Canine.

David Grimm writes about the research undertaken by Marc Bekoff, who studies dog play and that, “studying dog play reveals more than the animals’ emotional lives. It could ultimately shed light on the evolution of human emotions and how we came to build a civilisation based on laws and co-operation, empathy and altruism.”

Now that is a fascinating idea; that understanding why dogs play might help our understanding of how our emotions evolved. Up until this point, it had never occurred to me that our emotions evolved in just the same way that the rest of who we are today evolved. Sort of common-sense, I guess!

David Grimm goes on to write in that Washington Post article: “All of this suggests that dogs have a kind of moral code — one long hidden to humans until a cognitive ethologist named Marc Bekoff began to crack it.”

As I read the article it started to dawn on me that possibly the reason that we humans devote so much time, energy, and frequently money, in playing, may have much deeper roots, as with our dogs.

Few people had studied animal play, but Bekoff was intrigued. “Play is a major expenditure of energy, and it can be dangerous,” he says. “You can twist a shoulder or break a leg, and it can increase your chances of being preyed upon. So why do they do it? It has to feel good.”

Suddenly, Bekoff wasn’t interested just in behaviour; he was interested also in emotions and, fundamentally, what was going on inside these animals’ heads.

As the article reveals, Professor Bekoff, “wasn’t the first scientist to become intrigued by the canine mind”, reminding us that Charles Darwin was sure that dogs could engage in abstract thought, owned a sense of morality and used language. In Darwin’s lifetime he had thirteen dogs so had plenty of opportunity to become aware of what most of today’s dog owners know: that we humans and dogs can communicate with each other.

But back to emotions.

Back to David Grimm’s article:

Even morality hints at something deeper, however. To enforce moral conduct, dogs must be able to experience a spectrum of emotions, from joy to indignation, guilt to jealousy. They must also be able to read these emotions in others, distinguishing accident from intent, honesty from deceit. And indeed, recent studies by other scientists have shown evidence of these abilities (confirming what many dog owners already feel about their pets).

Scientists have found, for example, that dogs trained to shake hands with humans will stop shaking if they notice that they aren’t being rewarded for the trick although a nearby dog is — a sign, the researchers suggested, that dogs can sense inequity.

Thus from the playing of dogs (and wolves) comes great insight into the emotions and social conduct of humans. I will return to that idea at the end of the chapter.

Like millions of other dog lovers, I know from strong personal experience that dogs have a great sensitivity to how I am behaving and feeling. Even almost taking it for granted that when I yawn, the chances are that one of our dogs will yawn. Or believing, without any doubt, that dogs show empathy for us humans; I can easily recall my Pharaoh licking tears from my face. What I didn’t realise until reading the Washington Post article is that empathy is a rarely documented trait in the animal kingdom.

We know what our dogs are feeling from their behaviour and their vocal sounds. Know instinctively that when a dog nudges me awake in the early hours of the morning, it is because it needs to go outside for a ‘call of nature’ and can’t wait until the normal waking hour.

Our dogs know what we are feeling from our behaviours, our body ‘language’ and our vocal sounds.

We all, all of us dog owners that is, know this and take it for granted. Perhaps not quite in the clarity of Professor Bekoff’s recent work that “suggests another remarkable canine skill: the ability to know what another animal is thinking — a so-called “theory of mind.””

Back to play. Science is suggesting that play, as initially researched with dogs, is very important, incredibly so, to our species. That without play, us humans would have had an impossible task of learning or interacting with the world around us. That our insight into our human emotions and the way we conduct ourselves, in a social context, flows down from learning from dogs.

Leaving one inescapable conclusion, one that so perfectly links to community: never stop playing. Never stop playing with others; humans and dogs alike.

Whoops!

Yesterday, I published a chapter from ‘the book’ under the title of The Power of Negativity.

However, as I contemplated a number of chapters coming along that, taken collectively, might seem out of place in a book that, essentially, offers a positive message, I decided an introduction was called for.

Thus in thirty minutes time that introduction is published.

I also realised that this introduction should have come before yesterday’s chapter on negativity.

So for those of you that might be following my draft, you poor souls, try and come at the Introduction as if it had been presented before The Power of Negativity.

Now for a complete change of topic!

Neighbour Dordie recently sent me the following.  Here’s Part One.
