The power of a photograph

No words to say how I feel!

This is a terrible photograph. It has been widely shown but that doesn’t make it any less terrible.

Patrice Ayme recently wrote about the tragedy but for today I am republishing the article in The Conversation.

How much power can one image actually have?

When the Associated Press published Julia Le Duc’s photograph of a drowned Salvadoran man, Óscar Alberto Martínez Ramírez, and his 23-month old daughter Valeria, it sparked outrage on social media. According to Le Duc, Ramírez had attempted to cross the Rio Grande after realizing he couldn’t present himself to U.S. authorities to request asylum.

But beyond raising awareness via Twitter and Facebook feeds, does an image like this one have the power to sway public opinion or spur politicians to take action?

As journalism and psychology scholars interested in the effects of imagery, we study the ability of jarring photos and videos to move people from complacency to action. While graphic imagery can have an immediate impact, the window of action – and caring – is smaller than you’d think.

A political catalyst?

Photographs and videos – through their perceived authenticity – can have an effect on people.

Research suggests that the graphic photo of slain Emmett Till in his open casket served as a “political catalyst” in mobilizing Americans to action in the civil rights movement. Similarly, news images have been credited as playing an important role in ending the Vietnam War.

But not all scholars agree. A recent article argued that it was a “myth” that the iconic “napalm girl” photo swayed public opinion and hastened the end of the Vietnam War.

We must also look to psychology to understand the impacts of emotional news content. Research demonstrates that audiences need an emotional connection – and not merely a “just-the-facts” reporting approach – as “prerequisite for political action” when it comes to appreciating the importance of distant mass suffering. And imagery can trigger this emotional connection by overcoming the psychic numbing that occurs when casualties mount, images blur and lost lives become merely dry statistics.

Images from Syria

In April 2017, gut-wrenching images seem to have awakened the world to the human atrocities happening in Syria. Following a chemical bomb attack in the town of Khan Sheikhoun, graphic photos and videos documented the horrific effects of the banned nerve agent sarin. Millions bore witness to excruciating human suffering: gasping, choking, writhing and dying. More than 500 people were injured, with at least 86 deaths, including 28 children.

The vivid, closeup images of sarin attack victims were resonant enough to break through the complacency of people and politicians accustomed to bad news emerging from the war-torn nation. In President Trump’s response – which included a retaliatory missile strike – he seemed to recognize the value of the Syrian lives depicted in the horrific photos and videos.

“When you kill innocent children,” he said during a news conference, “that crosses many, many lines, beyond a red line – many, many lines.”

The limits of an image

Nonetheless, even though the attacks may have briefly heightened U.S. concerns over the wars in Syria, the photographic documentation of the suffering in Syria wasn’t new.

The 2015 photos of a tiny Syrian boy’s lifeless body resting face down in the sand similarly stirred the world’s collective consciousness. Within hours of its release, the photo had reached 20 million people through Twitter, with many more millions seeing it on the front pages of newspapers the next day. Afterwards, government restrictions on accepting refugees were loosened while private donations to organizations like the Red Cross spiked dramatically.

A year later haunting images of a young boy in the back of an ambulance, caked in dirt and blood, galvanized the world.

But the emotional and compassionate responses to both photographs were short-lived. The bombing of civilians in Syria continued. Refugees continued risking their lives to escape the war zone.

After a photograph of a dead Syrian boy went viral in 2015, the number of daily donations to a Swedish Red Cross campaign designated specifically for aiding Syrian refugees spiked dramatically – but only for a brief window. Proceedings of the National Academy of Sciences of the United States of America, CC BY-SA

Since the publication of Le Duc’s photo of the dead migrants, supportive politicians may feel emboldened to sound the alarm on the plight of Central American migrants. Donations to immigrant aid organizations might briefly spike.

But it seems that a photograph, no matter how emotionally devastating, can only do so much.

Yes, it can create a window of time when we’re motivated to act, and we’ll usually do so if we have effective options to pursue. This could mean a charitable donation at the individual level or, collectively, a surge of political will. However, psychology research from the “arithmetic of compassion” suggests that sympathy for distant human suffering declines when we’re presented with rising body counts. Sometimes we’re discouraged by the scope of the problem and this stops us from doing things that actually make a difference – even if partial solutions can save lives. Other times, if the options for helping others seem too narrow or ineffective, we’ll turn away and stop caring.

Images can alert us to the horrors of violence, mass migration and poverty. But as we have seen time and again, photographs and news footage of human suffering generally precipitate a short-term emotional reaction, rather than a sustained humanitarian response.

ooOOoo

As one reads the article it is much more than a comment on a single image despite how terrible that photograph may be.

The two scientists set out to show that the period that we are alarmed or terrified or just plain sad at the state of nations is rather short.

Maybe it’s the self-protective nature of our species that does this.

But it still doesn’t diminish the horror of that top photograph.

How a dog saved a family

This is a story of a very real emergency.

I have taken it from BoredPanda, not a site that I frequent, but this is such a marvellous account of how dogs make, every day, a real difference to the lives of people.

Man Shares A Heartwarming Story About How His Dog Saved His House From Burning Down

Dogs… if only there was a word that would show how much we adore these adorable creatures that we get to call our most loyal friends and also beloved family members. Here at Bored Panda, dogs (amongst other animals) have a very special place, despite the fact that they can do the worst things, we still adore them. Also, today’s story teaches us that just because your puppy did something wrong, don’t be too quick to punish them since they might compensate it by doing something truly heroic.

Recently, one Twitter user shared a heartwarming story about his dog Hank saving his entire family from fire

Hank even got some presents dedicated to his heroic act

People online were not only touched by this story, but they also think Hank deserves to chew all of the shoes in the world.

What does it mean when your dog gives you the ‘side-eye’?

by Dr. Karen Shaw Becker

June 25, 2019

Story at-a-glance

  • The term side-eye denotes a greater amount of “white” in a dog’s eyes, which is more pronounced when the dog averts his head slightly, but keeps his eyes fixed on something or someone at the same time
  • Some dogs, particularly brachycephalic dogs (dogs with short muzzles), appear to show the whites of their eyes most of the time, which doesn’t necessarily mean they’re feeling anything in particular
  • The side-eye may be a way for dogs to say “Back off,” and may precede some sort of aggression, especially if they’ve been guarding something like a toy — or food — and suddenly feel threatened
  • In studies of other types of canines, dingoes were found to initiate eye contact with a familiar human more often than wolves, but the duration was found to be shorter than the eye contact between humans and dogs
  • Dogs’ demeanor might appear to be excitement when they bark, whine, pant or pace, so it’s important to know your dog but also assess the situation that might be causing it

It’s been called the “whale eye,” that sidelong glance your dog gives you that communicates very strongly that something’s up. Also called the “side-eye,” it’s when the color white appears in a half-moon shape on either the right or left side of their eyes.

You may have seen dogs and their cute side-eye looks on social media. They can be quite comical, especially when the accompanying expressions match the captions. Nevertheless, it’s wise to know what your dog’s body language is trying to tell you, because as much as dogs might want to speak in human terms, they’re not able to.

So what does the whale eye mean? Trainers are said to use the term to describe a greater amount of “white” in a dog’s eyes as a means to communicate. It’s more pronounced when the dog averts his head slightly, but keeps his eyes fixed on something or someone at the same time.

Some dogs, particularly brachycephalic dogs (dogs with short muzzles), appear to show the whites of their eyes most of the time, which doesn’t necessarily mean they’re feeling anything in particular. Other examples of a dog’s body language, especially if you know what to look for, signify very specific things. Depending on the situation, you might be able to discern what it means fairly quickly.

Side-eye may be a way for dogs to say “Back off,” and usually precedes some sort of aggression, especially if they’ve been guarding something like a toy — or food — and suddenly feel threatened.1 According to Bark Post:

“This is pretty common behavior for dogs to exhibit. Obviously, that doesn’t mean we want them to keep doing it, but it’s important to realize this doesn’t mean you have a defective pup. He’s still the adorable, hilarious, wonderful … little guy or girl you love.

When coming across this sort of behavior, you should definitely give your pup the space they’re asking for. Back up and analyze the situation. Did you get too close to the bone they’ve been hiding for 72 hours?”2

Signs your dog is trying to tell you something

If your dog is giving the side-eye to another person the dog may not be familiar with, experts advise dog owners to be aware of the behavior and try to diffuse it. “Much of what’s required in mitigating this behavior is just removing the cause from the situation.”3

If your dog’s side-eye response is accompanied by a rigid stance or visible tension, it happens more than once and it’s evident it’s not just a sidelong glance, it could be stress-related, and it wouldn’t hurt to contact a positive dog trainer or behaviorist. In many ways, like people, there are a number of ways dogs communicate stress, tension and anxiety.

Sometimes their demeanor might appear to be excitement, such as behavior like barking, whining, panting or pacing. Dogs that feel uncomfortable or nervous might communicate it by hiding, relieving themselves in the house, cowering or shaking. At times, however, the signs may be much more subtle, such as if you notice them blinking, yawning, licking, swallowing or shedding more than usual.

If your pup shows the side-eye or other signs of stress, petting him gently with long, smooth strokes from their chest, shoulder and base of their tail will help relax him.4,5 It helps relieve tension and could even serve as a sort of “maintenance” to help keep them calm in out-of-the-ordinary situations.

How eye contact in other canine species denotes communication

While wolves (Canis lupus) and coyotes (Canis latrans) may not seem to have much in common with domestic dogs (Canis familiaris), experts place them in the same species. That great Danes and Chihuahuas are related to each other, not to mention these feral varieties, seems hard to believe, but domestic dogs came from wolves, and scientists say some wolf varieties may be coyote hybrids.

Dingoes, placed for years in the same canine designation as dogs, wolves and coyotes, have been deemed their own distinct species. They’re now formally called Canis dingo,6 even though they bear a remarkable resemblance to other canines. Over the last few centuries, their scientific names, such as Canis lupus dingo and Canis familiaris dingo, wrongly related them to the others.

Interestingly, a study7 on the origins of dog and human eye contact included all of the above species. It determined that dingoes establish eye contact less often than dogs do, but more often than wolves. In addition, dingoes were found to initiate eye contact with a familiar human more often than wolves, but the duration was found to be shorter than the eye contact between humans and dogs.

While words are the preferred mode of communication between humans, your dog may pay more attention to your posture, gestures and eye contact, possibly because they often use body language to communicate more than any other tool. They’re also in tune with your tone, and pick up from you more of your mindset than you might imagine.

Dogs’ body language changes around humans

Not only do dogs communicate with their humans with body language, they also do so with other dogs, especially when there’s more than one dog or several in a household. But the journal Nature cited a study8 showing that a dog literally “produces” more facial expressions when they’re looking straight at their significant humans. In fact, it:

“Support(s) for the idea that dogs do indeed produce facial expressions to communicate with people — although perhaps just to engage us, rather than to manipulate us. The dogs in the study produced more than twice as many facial expressions (‘puppy dog eyes’ was one of the most common) when a researcher was facing them than when she was turned away …

(It) adds to a growing body of work that shows how sensitive dogs are to human attention. It also provides the first evidence in a non-primate species that facial expressions can be used actively to communicate.”9

Psychology Today affirms that eyes are the “window to the soul.”10 If you’re a dog lover, you know you can share thoughts and feelings just by looking into your beloved pet’s eyes. It’s one of the signs that the bond between you is strong, and communicates mutual respect, as well. One more thing those eyes reveal is that the love your dog has for you is unconditional. Just watch out for those side-eyes.

Puppy Mills, Part Two

Part Two of this guest post from Monika.

ooOOoo

One of the more alarming facts surrounding the audit was a lack of enforcement against violators. Enforcement has been ineffective, particularly against the worst of the worst where little or no action against a majority of violators resulted. Of the enforcement decisions for 68 sampled violators, 71% (48) resulted in no action taken, 6%  (4) received a “Letter of Information,” 19% (13) received an Official Warning and 4% (3) resulted in Stipulation. In 2007 the AC discontinued using Letter of Information as an enforcement option. Only 20 of 68 dealers (nearly 30%) were cited for repeat violations.

States with Animal Cruelty Laws

Only 5 states have a subsequent-offense felony cruelty law (Arkansas, Idaho, North & South Dakota, Mississippi); and 5 States have a misdemeanor cruelty law (Alaska, Iowa, Nevada, Ohio, Pennsylvania, the remaining 40 states have a first-offense felony cruelty law.

We all know that puppy mills put profit over the health and well-being of the dogs but here are a few of the worst examples cited in the Audit.

Example No. 1. With 83 adult dogs, a Oklahoma breeder was sited with 20 violations during 5 inspections from April 2006 to December 2007. Lack of adequate vet care for 3 dogs hair-loss over their entire bodies and raw, irritated spots on their skins. Despite continuing violations, no enforcement actions were taken due to the agency’s lenient practices against repeat violators.

During another visit, AC cited breeder for another 11 violations (one involving a dog that had been bitten by another and left untreated for at least 7 days which resulted in the flesh around the wound rotting away to the bone! The inspector required the dog be taken to a local vet who immediately euthanized it. The case was referred to IES for investigation but only after another violation was documented. AC recommended a stipulation, yet as of early June 2009 (11 months following visit), violator had not been fined.

Example No. 2 was another OK facility with 219 adult dogs. Breeder was cited for 29 violations (including 9 repeats) during 3 inspections from February 2006 to January 2007. Yet the AC did not take enforcement action, but did request an investigation in November 2007 when another inspection revealed five dogs were found dead and other starving dogs resorted to cannibalism. When asked why dogs were not confiscated when the first dead and starving dogs were discovered, inspector cited its own regulations require violator be given opportunity to correct condition before confiscation can occur. Despite those conditions, the AC did not immediately confiscate the survivors, resulting in another 22 dogs dying before the breeder’s license was revoked and surviving dogs were rehomed within a year.

Example No. 3  involved a Ohio facility with 88 adult dogs. Breeder was cited for 23 violations including 7 repeats during 3 inspections from August 2005 to January 2008. An official warning was sent in July 2007 and in a subsequent visit in January 2008, found the same violations with another official warning sent rather than a more severe penalty. When asked by a more serious action was not taken, the regional manager indicated ‘breeder was making progress’ with a ‘reasonable opportunity’ to comply. National instructions state official warning can be sent if no other action was taken against a violator in the previous 3 years. Four months later in June 2008, breeder was cited for another 9 violations (4 repeats) yet the inspector recommended no enforcement action. Upon re-inspection 4 months later, breeder was cited for 4 more violations (including 3 repeats); AC took no enforcement action noting violator was “making credible progress.”

The USDA accompanied 19 of the 99 inspectors to observe dealer facility inspections. While many inspectors are highly committed, inspections are conducted timely and thoroughly and significant efforts are made to improve humane treatment of covered animals, it was noted that at least 6 inspectors did not correctly report direct or repeat violations. Some inspectors did not always document violations with sufficient evidence and direct violations were not reported. The Agency Guide defines a direct violation as one that “has a high potential to adversely affect the health and well-being of the animal” which include: “infestation with large numbers of ticks, fleas, or other parasites” and “excessive accumulations of fecal or other waste material to the point where odors, disease hazards, or pest control problems exist.” In such cases, a facility must be re-inspected within 45 days to ensure that the violator has taken timely actions to treat the suffering animals. By contrast, an indirect violation is one that “does not have a high potential to adversely affect the health and well-being of the animal.” Minor violations include: “inadequate records” and “surfaces not resistant to moisture.” In such cases, a re-inspection may not occur for up to a year.

Major deficiencies of the APHIS administration of the AWA cited in the Audit included:

  • AC’s enforcement process was ineffective against problematic dealers.
  • AC inspectors failed to cite or document violations properly to support enforcement actions.
  • AC inspectors failed to Cite or document violations properly to support enforcement actions.
  • APHIS’ new penalty worksheet calculated minimal penalties. Although APHIS previously agreed to revise its penalty worksheet to produce “significantly higher” penalties for violators of AWA, the agency continued to assess minimal penalties that did not deter violators. This occurred because the new worksheet allowed reductions up to 145 percent of the maximum penalty.
  • APHIS misused guidelines to lower penalties for AWA violators. In completing penalty worksheets, APHIS misused its guidelines in 32 of the 94 cases we reviewed to lower the penalties for AWA violators. Specifically, violations were inconsistently counted and applied “good faith” reductions without merit. A reduction in “no history of violations” when there was a prior history; and  arbitrarily changed the gravity of some violations and the business size. AC assessed lower penalties as an incentive to encourage violators to pay a stipulated amount rather than exercise their right to a hearing.
  • Some large breeders circumvented AWA by selling animals over the Internet. Large breeders that sell AWA-covered animals over the Internet are exempt from AC’s inspection and licensing requirements due to a loophole in AWA resulting in an increasing number of unlicensed breeders are not monitored for their animals’ overall health and humane treatment.

While the USDA does not advocate assessing maximum penalties, at a time when Congress tripled the authorized maximum penalty to “strengthen fines for violations,” actual penalties were down 20 percent less through the use of a new worksheet as compared to the one previously used.

I could go on, but to do so belies cold hard facts that trying to stem puppy mills is a bit like playing a ‘Whack-A-Mole.”

Bottom line, what the Audit tells us is: (1) red tape saddles agencies with convoluted regulations that are difficult to implement or monitor, due in part to (2) the sheer number of puppy mills and (3) a lack of adequate number of inspections conducted.

No doubt resources are limited but until such time as the economics of keeping puppy mills in business is reduced, they will continue to operate with impunity. The resulting advice is make sure your breeder is legit and don’t succumb to adorable puppy faces in pet shop windows.

I shudder to think how many of Elsa’s pups are out there because who easily resists puppies? It makes me wonder how many of them have genetic diseases due to poor breeding practices (in Elsa’s case epilepsy which was diagnosed just two weeks following her adoption), but other dogs seized at the same mill with her suffered from Sebaceous Adenitis (which is also most likely an autosomal recessive inherited disease), Addison’s Disease and one whose severe aggressive behavior (due to lack of socialization) was deemed so severe, he was considered unable to be rehabilitated in any way as to place him and heartbreakingly was euthanized. Bottom line, please adopt, don’t shop (or only use a reputable breeder). Only then can the sheer numbers of puppy mill facilities be reduced and heartbreaking stories like Elsa’s be stemmed.

Puppy Mills

By Monika McDonald

Puppy Mills…a topic that’s near and dear to my heart. Elsa, a Standard Poodle who probably lived 4 years or more in a mill, was rescued from a Northern Colorado puppy mill along with 8 other Standards (you can  read her story at the link). She was basically feral, shy but very sweet and curious and showed signs there was a lovely sweet companion beneath the matted filthy hair.

Recently I was given the opportunity to write a guest post for Paul at Learning from Dogs. Hold on to your hankies while I share some of the more disturbing facts uncovered from various sources. After much negative media coverage concerning large-scale dog dealers (i.e. breeders and brokers) failing to adequately monitor humane treatment for the animals under their care, the United States Department of Agriculture conducted an audit in 2010, some findings of which are noted below. Although Elsa was rescued through the local poodle rescue organization, I’m also featuring another group, the National Mill Dog Rescue group, headquartered in Colorado Springs, Colorado.

It is estimated there may be as many as 15,000 mills throughout the country, with a large number located in the heartland of the US. Simply put, puppy mills are dog breeding operations that put profit over the health and well-being of the dogs.

They can be a large or small operation, licensed by the USDA or unlicensed. It should be noted that in order to sell to a pet store, a breeder must be licensed, though many violate that requirement. According to the USDA, breeders…breed and raise animals on the premises whereas brokers negotiate or arrange for the purchase, sale or transport of animals in commerce. Puppy mills may house anywhere from hundreds to thousands of dogs, however smaller does not necessarily mean better.

Elsa was rescued from a very small mill with the same horrific conditions as the large ones. Puppy mills are everywhere, but a large concentration is located in the Midwest. Missouri has the largest number of puppy mills in the United States. Amish and Mennonite communities (particularly in Ohio, Indiana, and Pennsylvania) also run a large number of puppy mills.

Breeding parents spend their lives in 24-hour confinement in cages often stacked on top of each other. Protection from heat, cold, or inclement weather is rare and dogs live in filthy, unsanitary conditions receiving little or no veterinary care (some puppy mill owners often provide veterinary care without anesthesia or vet training). Female dogs are bred every heat cycle and are killed (or offered at auction) when they can no longer produce litters. Puppies are often taken from their mothers too young and can develop serious health or behavioral issues due to the conditions in which they are bred and shipped. Genetic diseases often result from the over-breeding. The bottom line is that puppy mills are all about profits. Any money spent on veterinary care, quality food, shelter, or staff to care for the dogs cuts into the profit margin.

Where are puppy mill puppies sold? Two primary sales outlets for puppies bred in  mills are pet stores, and the Internet. Nearly all puppies sold at pet stores come from puppy mills. Pet stores are the primary sales outlet for puppy mills and are essential for keeping puppy mills in business. Both licensed and unlicensed mills sell to pet stores with many mills selling to pet stores without the required license and not held accountable. Puppies are bred in mills and then shipped all over the country. Shipping conditions are inhumane. They can be forced to go up to 12 hours without food or water, and confined in a small space where diseases can be easily transmitted. Many puppies do not survive.

Background Info. In 1966, Congress passed Public Law 89-544, known as the Laboratory Animal Welfare Act, to regulate the humane care and handling of dogs, cats, and other laboratory animals. In 1970 the law was amended (Public Law 91-579), changing the name to Animal Welfare Act (with subsequent amendments passed in 1970, 1976, 1985, 1990, 2002, 2007, and 2008). In 2010 the USDA conducted an audit of the Animal and Plant Health Inspection Service’s (APHIS) Animal Care unit (AC) who are responsible for enforcing the act (the “Audit)”. Data cited is compiled from that Audit.

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)

July 19, 2017

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.

When did we come together?

A cache of animal bones 11,500 years old suggests an answer.

Brigit Katz of The Smithsonian wrote an article in January that revealed that dogs and humans hunted together many thousands of years ago.

Here it is:

When and where dogs came to be domesticated is a subject of scientific debate, but there is a wealth of research that attests to the long, intertwined history of humans and their best animal buddies. One theory about the early origins of this relationship posits that dogs were used to help early humans hunt. And, as Ruth Schuster reports for Haaretz, a new study suggests that this may have been the case among prehistoric peoples of what is now Jordan.

A team of archaeologists from the University of Copenhagen and University College London studied a cache of animal bones at an 11,500-year-old settlement called Shubayqa 6, which is classified as “Pre-Pottery Neolithic A,” or belonging to the first stage of Neolithic culture in the Levant. In the Journal of Anthropological Archaeology, the researchers write that they found bones from a canid species, though they could not identify which one because the remains were poorly preserved. They also unearthed the bones of other animals that had been butchered. But perhaps most intriguing were the bones of animals—like gazelle, for instance—that bore clear signs of having passed through a digestive tract.

These bones were too big for humans to have eaten, leading the researchers to surmise that they “must have been digested by dogs,” says lead study author Lisa Yeomans, a zooarchaeologist at the University of Copenhagen. And the researchers don’t think this was a case of wild carnivores sneaking into the settlement to grab a bite.

For one, archaeological evidence indicates that Shubayqa 6 was occupied year-round, suggesting that “dogs were allowed to freely roam around the site picking over the discarded waste, but also defecating in the vicinity of where humans were inhabiting,” the study authors write.

There was also a noticeable surge in hare bones around the time that dogs started to appear at the site, and the researchers think this may be because the dogs were helping humans hunt small prey. Previously, the people of Shubayqa 6 might have relied on tools like netting to catch hares and other animals, says Yeomans, but it wouldn’t have been very effective. Dogs, on the other hand, could selectively target elusive prey.

Humans and dogs thus appear to have forged a reciprocal relationship in Jordan more than 11,000 years ago. There is in fact evidence to suggest that dogs were domesticated by humans in the Near East as early as 14,000 years ago, and some of that evidence seems to point to dogs being used during hunts. Rock art from a site near Shubayqa, for instance, seems to show dogs driving gazelle into a trap.

In light of such archaeological finds, “it would be strange not to consider hunting aided by dogs as a likely explanation for the sudden abundance of smaller prey in the archaeological record,” Yeomans says. Among the ancient peoples of Jordan, in other words, the complex history of dog domestication may have been well underway.

That scientific debate mentioned in the first line of the article has been published in this place before. But I’m going to republish it tomorrow as it so perfectly goes with today’s post.

More on meteorites.

I saw this story very late yesterday.

This was read quickly towards the end of the day, as in yesterday, but I thought it well worthwhile rescheduling my doggie article until Saturday and putting this in for today.

Later on yesterday it was read more thoroughly and it is full of fascinating information such as the weight of meteorites that fall onto Planet Earth each day. I wasn’t aware of that.

Anyway, hope you too find it of interest.

The tell-tale clue to how meteorites were made, at the birth of the solar system

June 6th, 2019.

April 26, 1803 was an unusual day in the small town of L’Aigle in Normandy, France – it rained rocks.

Over 3,000 of them fell out of the sky. Fortunately no one was injured. The French Academy of Sciences investigated and proclaimed, based on many eyewitness stories and the unusual look of the rocks, that they had come from space.

The Earth is pummeled with rocks incessantly as it orbits the Sun, adding around 50 tons to our planet’s mass every day. Meteorites, as these rocks are called, are easy to find in deserts and on the ice plains of Antarctica, where they stick out like a sore thumb. They can even land in backyards, treasures hidden among ordinary terrestrial rocks. Amateurs and professionals collect meteorites, and the more interesting ones make it to museums and laboratories around the world for display and study. They are also bought and sold on eBay.

Despite decades of intense study by thousands of scientists, there is no general consensus on how most meteorites formed. As an astronomer and a geologist, we have recently developed a new theory of what happened during the formation of the solar system to create these valuable relics of our past. Since planets form out of collisions of these first rocks, this is an important part of the history of the Earth.

The mysterious chondrules

About 10% of meteorites are pure iron. These form through a multi-step process in which a large molten asteroid has enough gravity to cause iron to sink to its center. This builds an iron core just like the Earth’s. After this asteroid solidifies, it can be shattered into meteorites by collisions with other objects. Iron meteorites are as old as the solar system itself, proving that large asteroids formed quickly and fully molten ones were once abundant.

The other 90% of meteorites are called “chondrites” because they are full of mysterious, tiny spheres of rock known as “chondrules.” No terrestrial rock has anything like a chondrule inside it. It is clear that chondrules formed in space during a brief period of intense heating when temperatures reached the melting point of rock, around 3,000 degrees Fahrenheit, for less than an hour. What could possibly account for that?

Researchers have come up with many hypotheses through the last 40 years. But no consensus has been reached on how this brief flash of heating happened.

The chondrule problem is so famously difficult and contentious that when we announced to colleagues a few years ago that we were working on it, their reaction was to smile, shake their heads and offer their condolences. Now that we have proposed a solution we are preparing for a more critical response, which is fine, because that’s the way science advances.

The flyby model

Our idea is quite simple. Radioactive dating of hundreds of chondrules shows that they formed between 1.8 and 4 million years after the beginning of the solar system – some 4.6 billion years ago. During this time, fully molten asteroids, the parent bodies of the iron meteorites, were abundant. Volcanic eruptions on these asteroids released tremendous amounts of heat into the space around them. Any smaller objects passing by during an eruption would experience a short, intense blast of heat.

To test our hypothesis, we split up the challenge. The astronomer, Herbst, crunched the numbers to determine how much heating was necessary and for how long to create chondrules. Then the geologist, Greenwood, used a furnace in our lab at Wesleyan to recreate the predicted conditions and see if we could make our own chondrules.

The experiments turned out to be quite successful.

We put some fine dust from Earth rocks with compositions resembling space dust into a small capsule, placed it in our furnace and cycled the temperature through the predicted range. Out came a nice-looking synthetic chondrule. Case closed? Not so fast.

Two problems emerged with our model. In the first place, we had ignored the bigger issue of how chondrules came to be part of the whole meteorite. What is their relationship to the stuff between chondrules – called matrix? In addition, our model seemed a bit too chancy to us. Only a small fraction of primitive matter will be heated in the way we proposed. Would it be enough to account for all those chondrule-packed meteorites hitting the Earth?

Making whole meteorites

To address these issues, we extended our initial model to consider flyby heating of a larger object, up to a few miles across. As this material approaches a hot asteroid, parts of it will vaporize like a comet, resulting in an atmosphere rich in oxygen and other volatile elements. This turns out to be just the kind of atmosphere in which chondrules form, based on previous detailed chemical studies.

We also expect the heat and gas pressure to harden the flyby object into a whole meteorite through a process known as hot isostatic pressing, which is used commercially to make metal alloys. As the chondrules melt into little spheres, they will release gas to the matrix, which traps those elements as the meteorite hardens. If chondrules and chondrites form together in this manner, we expect the matrix to be enhanced in exactly the same elements that the chondrules are depleted. This phenomenon, known as complementarity, has, in fact, been observed for decades, and our model provides a plausible explanation for it.

The authors’ model for forming chondrules. A small piece of rock (right) — a few miles across or less — swings close to a large hot asteroid erupting lava at its surface. Infrared radiation from the hot lava briefly raises the temperature on the small piece of rock high enough to form chondrules and harden part of that object into a meteorite. W. Herbst/Icarus

Perhaps the most novel feature of our model is that it links chondrule formation directly to the hardening of meteorites. Since only well-hardened objects from space can make it through the Earth’s atmosphere, we would expect the meteorites in our museums to be full of chondrules, as they are. But hardened meteorites full of chondrules would be the exception, not the rule, in space, since they form by a relatively chancy process – the hot flyby. We should know soon enough if this idea holds water, since it predicts that chondrules will be rare on asteroids. Both Japan and the United States have ongoing missions to nearby asteroids that will return samples over the next few years.

If those asteroids are full of chondrules, like the hardened meteorites that make it to the Earth’s surface, then our model can be discarded and the search for a solution to the famous chondrule problem can go on. If, on the other hand, chondrules are rare on asteroids, then the flyby model will have passed an important test.

Perfect timing!

Saving a bald eagle.

This has nothing to do with dogs but it’s a beautiful story none the less!

I follow the Daily Dodo as it most frequently relays lovely stories about dogs.

But not always.

On the 28th May Lily Feinn wrote about the way that dozens of motorists avoided a bald eagle on the freeway and one in a particular, Dandon Miller, a motorcyclist, did much more than that. He saved her!

Guy Sees A Bald Eagle Caught In Traffic — And Saves Her Life

“It was just amazing to hold that bird and for her to be calm like that.”

Dandon Miller’s favorite piece of clothing is a red and black flannel. He’s had the shirt for eight years and wears it all the time — but he never thought it would one day come in handy when saving a life.

On Saturday of Memorial Day weekend, Miller was on his way home from Philadelphia when traffic slowed in front of him. Miller pulled his motorcycle off to the side of the two-way highway and was shocked when he realized what was causing the traffic jam.

“I looked down to see why everyone was stopping and there was a bald eagle in the middle of the road,” Miller told The Dodo. “Another person was there and they kind of nudged her a little bit to see if she would walk off the road or fly away. She spread her wings open and was not going to go anywhere.”

An avid animal lover, Miller knew he had to help the injured bird get out of harm’s way.

The large animal was too hurt to fly, but her powerful talons were reason enough for Miller to take off his favorite flannel and throw it over her. To Miller’s surprise, the eagle remained sedate as he wrapped her in the shirt.

“I picked her up and she was very calm,” Miller said. “She got a little worked up when people started wanting to take pictures, but we were able to get that under control.”

Once Miller moved the eagle out of the road, he called 911 and eventually got in touch with Tri-State Bird Rescue and Research, a local rehabilitation center for wild birds. Miller held the 15-pound bird for about 45 minutes while waiting for rescue staffers to arrive. But the time seemed to pass quickly.

“I wasn’t really thinking about it when I was holding her,” Miller said. “I was just trying to keep her calm and make sure she knows she’s secure, and I wasn’t going to drop her or anything.”

“It was just amazing to hold that bird and for her to be calm like that,” Miller added. “Just amazing.”

After a few days of treatment, the rescue is confident that the bald eagle will eventually be able to be released into the wild.

“She had a mild injury to one eye and soft tissue injuries, but no broken bones,” Rebecca Stansell with Tri-State Bird Rescue and Research told The Dodo. “Her wounds were treated by our wildlife veterinarian while the eagle was under anesthesia. The unexpected can always happen, but we are optimistic that she will make a full recovery.”

As for Miller’s favorite flannel, it has certainly seen better days.

The shirt now has a few large talon holes in it, but Miller knows it was for the best cause — and he will definitely be wearing it again.

To help the bald eagle get the care she needs, you can make a donation to Tri-State Bird Rescue and Research.

I can’t really imagine what it felt like to hold that eagle in your arms for 45 minutes. Especially with all the traffic rushing past. But for sure it felt more than amazing. A beautiful wild eagle!

One can’t have too many opportunities to meld with the natural world.

Wonderful story!
