The origins of the dog

Dogs and humans go back even further than previously thought.

Humans and dogs were constant companions well before our ancestors settled in villages and started growing crops 10,000 years ago

I have no doubt that thousands of dog owners all around the world must be enthralled by the way that dogs relate to us and, in turn, how we humans relate to dogs. More than once a day, one of our dogs will do something that has me and Jean marvelling at their way of living so close to us.

Then when one starts to reflect on how long dogs and humans have been together, perhaps it could be seen as the direct result of that length of relationship.

Now there’s nothing new in me writing this, after all the home page of Learning from Dogs states:

Yet they have been part of man’s world for an unimaginable time, at least 30,000 years. That makes the domesticated dog the longest animal companion to man, by far!

Back in May the website Livescience published an article that revealed more about the length of our relationship with dogs. This is how it opened:

Ancient Wolf DNA Could Solve Dog Origin Mystery

by Becky Oskin, Senior Writer

Humans and dogs were constant companions well before our ancestors settled in villages and started growing crops 10,000 years ago, a new study suggests.

Genetic evidence from an ancient wolf bone discovered lying on the tundra in Siberia’s Taimyr Peninsula reveals that wolves and dogs split from their common ancestor at least 27,000 years ago. “Although separation isn’t the same as domestication, this opens up the possibility that domestication occurred much earlier than we thought before,” said lead study author Pontus Skoglund, who studies ancient DNA at Harvard Medical School and the Broad Institute in Massachusetts. Previously, scientists had pegged the wolf-dog split at no earlier than 16,000 years ago.

The Livescience article referred to results that were published in the journal Current Biology on May 21st this year. One needs a subscription to read the full report but here is their summary:

The origin of domestic dogs is poorly understood [ 1–15 ], with suggested evidence of dog-like features in fossils that predate the Last Glacial Maximum [ 6, 9, 10, 14, 16 ] conflicting with genetic estimates of a more recent divergence between dogs and worldwide wolf populations [ 13, 15, 17–19 ]. Here, we present a draft genome sequence from a 35,000-year-old wolf from the Taimyr Peninsula in northern Siberia. We find that this individual belonged to a population that diverged from the common ancestor of present-day wolves and dogs very close in time to the appearance of the domestic dog lineage. We use the directly dated ancient wolf genome to recalibrate the molecular timescale of wolves and dogs and find that the mutation rate is substantially slower than assumed by most previous studies, suggesting that the ancestors of dogs were separated from present-day wolves before the Last Glacial Maximum. We also find evidence of introgression from the archaic Taimyr wolf lineage into present-day dog breeds from northeast Siberia and Greenland, contributing between 1.4% and 27.3% of their ancestry. This demonstrates that the ancestry of present-day dogs is derived from multiple regional wolf populations.

That summary page also includes the following Graphical Abstract:

I don’t have permission to republish the Livescience article in full but would like to offer the closing paragraphs of this fascinating report.

“It is a very well-done paper,” Perry [George Perry, an expert in ancient DNA at Pennsylvania State University] told Live Science. “This topic is a critical one for our understanding of human evolution and human-environment interactions in the Paleolithic. Partnership with early dogs may have facilitated more efficient hunting strategies.”

If dogs first befriended hunter-gatherers, rather than farmers, then perhaps the animals helped with hunting or keeping other carnivores away. For instance, an author of a new book claims humans and dogs teamed up to drive Neanderthals to extinction. Skoglund also suggested the Siberian husky followed nomads across the Bering Land Bridge, picking up wolf DNA along the way.

“It might have been beneficial for them to absorb genes that were adapted to this high Arctic environment,” Skoglund said.

This is the first wolf genome from the Pleistocene, and more ancient DNA from prehistoric fossils could provide further insights into the relationship between wolves, dogs and humans, the researchers said.

Yes, our dogs have been part of man’s world for an unimaginable time – and Jean and I, as with tens of thousands of others, can’t imagine a world without dogs.

A story about a Pit Bull that will touch the soul.

The Pit Bull dog breed gets a very bad press thanks to the despicable way that these dogs were associated with dog fighting many years ago. But take away man’s disgraceful involvement and most times you will find a gorgeous, loving dog.

We have a Pit Bull mix here at home.

Rescued pit bull helps autistic teen open his heart

The first time Joey Granados gave his mother a kiss on the cheek was when they adopted Roxy.

Pit bulls often get a bad rap. So do kids with autism.

Both are misunderstood. But what happens when you put the two of them together? Magic.

Just ask Amanda Granados of Los Angeles. Her son, Joey, has autism. From an early age, Joey turned away from his mom’s hugs and kisses. He would not let his mom hold his hand. He preferred to be alone. According to his mom, Joey had a really difficult time adjusting in social situations.

But Joey has recently met a new friend that has opened up his heart to his mom and others in his world. That friend is Roxy, a goofy, loving pit bull who knows how it feels to have people look at you and think you are something you are not.

Fourteen-year-old Joey had been asking his mom for a dog for some time to help him deal with the loneliness of his life with autism. Just after Thanksgiving, Amanda was perusing the website for the local animal shelter when she came across Roxy’s picture and just knew that this would be a good match.

As Joey tells it, when he and his mom went down to the shelter to look at Roxy, the dog walked right passed Amanda and jumped on Joey’s lap. The two have been best friends ever since. And Roxy has opened up Joey’s world to the love and affection of others.

“I get emotional thinking about it,” Amanda Granados recently told “Today.” “For all those years, he wouldn’t hold my hand, he wouldn’t hug me — it was all part of the autism — but this dog has taught him how to give and show affection. He holds my hand now! He hugs me! The first time I got a kiss on the cheek was when Roxy came home.”

Joey told “Today” that Roxy has made it easier for him to give and receive affection.

“I didn’t have too many friends growing up, but then we got Roxy and I’ve been able to make friends ever since,” Joey said. “At home, I’ve been able to hold my mom’s hand, kiss her, hug her and do a lot of things that I hadn’t been able to do growing up.

“She’s opened up my heart.”

According to Amanda, the best part about the bond between Roxy and Joey is that there are no judgments. Just true friendship. And lots and lots of love.

Just doing one thing at a time.

The way a dog focuses on the immediate task holds a very important lesson for us.

It’s a safe bet to claim that any dog owner has, from time to time, envied the way a dog so perfectly lives in the present. Then let’s not even go to the comparison between dogs and humans when it comes to relaxing!

These opening thoughts were prompted by a recent article that was published on The Conversation. The article criticised, rightly in my opinion, the madness (my word) of how many of us live these days, and with particular respect to ‘multi-tasking’. It’s a sobering reminder of the value of letting go and is republished here within the terms of essays published on The Conversation.

The value of unplugging in the Age of Distraction

July 7, 2015 4.59am EDT

Author: John Rennie Short – Professor, School of Public Policy at University of Maryland, Baltimore County.

A common experience: you are walking down the street and someone is walking in the opposite direction toward you. You see him but he does not see you. He is texting or looking at his cellphone. He is distracted, trying to do two things at the same time, walking and communicating.

There is also the telltale recognition of a car driver on a phone; she’s driving either too slowly or too fast for the surrounding conditions, only partly connected to what is going on around her. Connected to someone else in another place, she is not present in the here and now.

These types of occurrences are now common enough that we can label our time as the age of distraction.

A dangerous condition

The age of distraction is dangerous. A recent report by the National Safety Council showed that walking while texting increases the risk of accidents. More than 11,000 people were injured last year while walking and talking on their phones.

Even more dangerous is the distracted car driver. Distracted drivers have more fluctuating speed, change lanes fewer times than is necessary and in general make driving for everyone less safe and less efficient.

Texting while driving resulted in 16,000 additional road fatalities from 2001 to 2007. More than 21% of vehicle accidents are now attributable to drivers talking on cellphones and another 5% were text messaging.

Cognitive impairment

Multitasking relatively complex functions, such as operating handheld devices to communicate while walking or driving, is not so much an efficient use of our time as a suboptimal use of our skills.

We are more efficient users of information when we concentrate on one task at a time. When we try to do more than one thing, we suffer from inattention blindness, which is failing to recognize other things, such as people walking toward us or other road users.

Digital devices, which are proliferating in our lives, encourage multitasking, but does this really help our performance?  Thomas Hawk/flickr, CC BY-NC-SA

Multitaskers do worse on standard tests of pattern recognition and memory recall. In a now classic study, researchers at Stanford University found that multitaskers were less efficient because they were more susceptible to using irrelevant information and drawing on inappropriate memories.

Multitasking may not be all that good for you either. A 2010 survey of over 2,000 8- to 12-year-old girls in the US and Canada found that media multitasking was associated with negative social indicators, while face-to-face contact was associated with more positive social indicators such as social success, feelings of normalcy and hours of sleep (vital for young people).

Although the causal mechanism has yet to be fully understood – that is, what causes what – the conclusion is that media multitasking is not a source of happiness.

Distraction-seeking creatures?

There are a number of reasons behind this growing distraction.

One often-cited reason is the pressure of time. There is less time to accomplish all that we need to do. Multitasking then is the result of the pressure to do more things in the same limited time. But numerous studies point to the discretionary use of time among the more affluent, and especially more affluent men. The crunch of time varies by gender and class. And, paradoxically, it is less of an objective constraint for those who often articulate it most.

Although the time crunch is a reality, especially for many women and lower-income groups, the age of distraction is not simply a result of a time crunch. It may also reflect another form of being. We need to reconsider what it means to be human, not as continuous thought-bearing and task-completing beings but as distraction-seeking creatures that want to escape the bonds of the here-and-nowness with the constant allure of someone and somewhere else.

Media theorist Douglas Rushkoff asserts that our sense of time has been warped into a frenzied present tense of what he calls “digiphrenia,” the social media-created effect of being in multiple places and more than one self all at once.

There is also something sadder at work. The constant messaging, emailing and cellphoning, especially in public places, may be less about communicating with the people on the other end as about signaling to those around that you are so busy or so important, so connected, that you exist in more than just the here and now, clearly a diminished state of just being.

There’s greater status in being highly connected and constantly communicating. This may explain why many people speak so loudly on their cellphones in public places.

Reactions

The age of distraction is so recent we have yet to fully grasp it. Sometimes art is a good mediator of the very new.

A video art installation by Siebren Verstag is entitled Neither There nor There. It consists of two screens. On one side a man sits looking at his phone; slowly his form loosens as pixels move to the adjacent screen and back again. The man’s form moves from screen to screen, in two places at one time but not fully in either.

One study that looked at the effect of banning cellphones in schools found that student achievement improved when cellphones were banned, with the greatest improvements accruing to lower-achieving students, who gained the equivalent of an additional hour of learning a week.

On many college campuses, faculty now have a closed-laptop policy after finding students would use their open laptops to skim their emails, surf the web and distract their neighbors. This was confirmed by studies that showed that students with open laptops learned less and could recall less than students with their laptops closed.

We are witnessing a cultural shift occurring with the banning of devices, cellphone usage being curtailed in certain public places and policies banning texting while driving. This is reactive. We also need a new proactive civic etiquette so that the distracted walker, driver and talker have to navigate new codes of public behaviors.

Many coffee stores in Australia, for example, do not allow people to order at the counter when they are on the cellphone, more golf clubs are banning the use of cellphones while on the course and it is illegal in 38 states in the US for novice drivers to use a cellphone while driving.

There is also the personal decision available to us all, one foreshadowed by writer and social critic Siegfried Kracauer, who lived from 1889 to 1966. In a newspaper article on the impact of modernity, first published in 1924, he complained of the constant stimulation, the advertising and the mass media that all conspired to create a “permanent receptivity” that prefigures our own predicament in a world of constant texting, messaging and cellphones.

One response, argued Kracauer, is to surrender yourself to the sofa and do nothing, in order to achieve a “kind of bliss that is almost unearthly.”

One radical response is to unplug and disconnect, live in the moment and concentrate on doing one important thing at a time. Try it for an hour, then for a day. You can even call your friends to tell them about your success – just not while walking or driving, or working on your computer screen or speaking loudly in a public place.

The Nose of the Dog

Originally published on September 3rd, 2012.

The incredible power of smell that dogs have.

The nose of a German Shepherd dog!

Regular readers will know that I subscribe to the blog Naked Capitalism masterminded by Yves Smith.  Some time ago, there was a link on NK to a story about how a tiny Chihuahua dog rescued some missing girls.  It seemed like a good opportunity to take a closer look at this most magical aspect of a dog’s qualities.

First to that story.

I saw it on the Care2 website, from which I quote the following:

Bell

Hero Chihuahua Finds Missing Girls in the Woods

by  August 2, 2012

A 3-year-old chihuahua named Bell is an unexpected hero after finding three young girls who became lost for hours in the woods in Newnan, Georgia, on Monday.

CBS Atlanta reports that, on Monday, 8-year-old Carlie and 5-year-old Lacey Parga went for a walk with their dog Lucy down a cul-de-sac on trails near their neighborhood.

What started as a casual stroll became an unintended, and at times frightening, experience. As Carlie tells CBS, ‘”We tried to find our way out of the woods. We kept following paths and stuff and we got lost.” Indeed, they became scared that they were only to get more and more lost.

Carlie’s father, David Parga, noted that it wasn’t characteristic of them to wander off and, after searching for them but not hearing them respond, he contacted police and firefighters. Neighbors joined them including Carvin Young who thought to take Bell, who plays with the girls every day and knew their scent. Bell was able to lead searchers to the girls.

The full story on the Care2 website is here and on the CBS website here.

So what is it about the nose of the dog?  A dog has more than 220 million olfactory receptors in its nose, while humans have only five million, making dogs’ sense of smell a thousand times greater.  Frankly, trying to get one’s intellect around precisely what having a sense of smell one thousand times greater than a human means is tough!  So on to another story.

The Bark and Clark blogsite reported an item in February that had been seen in the K9 Magazine.

17 Dogs, 3 Generations, 70 Years.
There’s one constant…
…the family dog.

After moving to Wellesley, Massachusetts for an anchor job with a major television sports network, Kevin began taking his German Shepherd, Beverly, for walks in the surrounding neighborhoods. They developed a route that included historic Atwood Street. Beverly kept veering toward one house in particular that had also caught Kevin’s eye previously, thinking it looked familiar but not knowing the reason.

After talking to a close family relative who had also once lived in Wellesley, Kevin was shocked to discover that the memorable house had once been a childhood home to his father, Bob Walsh, before WWII. After digging through old family photos that had been tucked away for years, Kevin uncovered a picture of his father as a toddler with his family on the house’s front porch, complete with their first family dog, Dee Dee.

Kevin’s father had been writing short stories about all of their family dogs through the years, but never knew about the photo. Its discovery was the pivotal moment that offered proof that the Walsh family’s journey with dogs had come back to the exact place where it started.

They’ve turned this story, along with other dog tales, into a book called Follow the Dog Home: How a Simple Walk Unleashed an Incredible Family Journey.

Dog’s nose leads family to back long lost old home, site unseen. German Shepherd, Beverly, is chronicled on WCVB TV’s news magazine show Chronicle. 70 years later, the family goes back “home” for stunning reunion and photograph.

Fire, forensics and a dog’s nose!

Fire dogs; another aspect of Man’s Best Friend.

A colleague back in England was speaking to me recently about a series on BBC Television about forensics. The series is called Catching History’s Criminals: The Forensics Story.

Apparently, the third in the series Instruments of Murder (For UK readers the link is here.) included fire being used as a criminal act. That episode featured a dog named Gunner who was a fire forensics dog. To the surprise of both Jean and me, while we were very aware of the sniffer dogs used by the police in many countries, neither of us had previously been aware that dogs were used, at times, in the determination of the cause of fire.

Now listen to Nikki Harvey of Hertfordshire Fire and Rescue Service in this YouTube video:

Published on Jul 23, 2013

Trained from a puppy by his partner in crime and handler, Nikki Harvey, Reqs (pronounced Rex) qualified as Hertfordshire Fire and Rescue Service’s new fire investigation dog in April this year. At a special event on Monday (22 July) Reqs launched his Twitter account and demonstrated his skills at Longfield Training Centre, Stevenage.

The 22-month-old black Labrador is taking over responsibility for helping to investigate the cause of fires in Hertfordshire and surrounding counties. His predecessor, seven year old CC, will work alongside Reqs until he retires.

Richard Thake, Cabinet Member for Community Safety and Planning said: “The work that Reqs does is critical in assisting the Hertfordshire Fire and Rescue Service team and it plays an integral part in community fire safety. Reqs is exceptionally valuable and receives the same high degree of training that we afford all frontline fire personnel.”

From six months old Reqs was trained to sniff out traces of ignitable liquids such as petrol, white spirit and lighter fluid which can remain present even after the most severe fire. Fire investigation officers use Reqs to assist them in determining the cause and origin of fires – whether deliberate or accidental. At the event he proudly gave a demonstration of sniffing out accelerants in a house and a car, as well as riding on an Arial Ladder Platform (ALP) that reaches up to seven floors, can be used as a water tower to extinguish large fires, and forms a safe platform for working at height.

Hertfordshire’s Chief Fire Officer Roy Wilsher said: “Reqs helps out on serious and non-serious cases and knowing what starts a fire helps us enormously in getting important fire safety messages out to the public. We want to prevent fires and keep people safe and now that Reqs is on Twitter his followers will learn a lot of useful tips to prevent accidental fires.

“I use Twitter myself (@HertsFireChief) and social networking is a great way to spread our safety messages across Hertfordshire.”

Fire investigation dogs are used for their speed and accuracy and are proving very successful in their work. Reqs and CC have assisted in many high profile incidents including suicides, fatal fires, arson attacks and murder investigations.

Reqs’ handler, Nikki Harvey said: “We’ve been training together for nearly two years now, which has given us the opportunity to get to know each other and build up trust which is essential. Ongoing training is now part of Reqs’ daily routine and it’s important that he always enjoys the ‘game’. I’m really looking forward to putting Reqs’ new skills to use.”

Reqs is the third fire investigation dog for Hertfordshire Fire and Rescue Service and is sponsored by Hatfield based company Computacenter UK Ltd, who also sponsor CC and his predecessor Browza. Clare Rafferty, Head of Corporate Events, Computacenter (UK) Ltd said: “The Fire investigation dog is a valuable asset to the Fire and Rescue Service and we are yet again delighted to extend that sponsorship to Reqs who is very worthy of stepping into CC’s shoes.”

And to demonstrate that these wonderful dogs undertake these roles both sides of the “pond”, here is a video from Denver, Colorado:

Published on Feb 23, 2015

Victoria travels to Denver, Colorado to check in on experienced arson investigator Jerry Means and his third arson dog, Riley. Jerry shows Victoria how he continues to train Riley, visits his office at the Colorado Bureau of Investigation, and takes her to a burn building to demonstrate live fire and extended training for Riley. Part 1 of 2

All of which seems like a great nudge for me to republish a post from Learning from Dogs from September, 2012 that explained a little more about the incredible power of the dog’s nose! See you tomorrow.

Dogs – What incredible companions!

Meet Lizzy The Dancing Dog and her Human Sandra Roth.

Last Saturday, I posted Let’s dance today!

It showed a dog dancing to music, or quite possibly, a dog scratching its back against a wall that someone had cleverly set to music.  The video had been sent to me by Chris Gomez.

Then Dan, a brother to Chris, and a close personal friend of mine for 35+ years, sent me the following. This is in a different league to Saturday’s little video. This raises questions as to how the dog was trained to perform like this? How long did it take? What’s the story behind the display?

All I could discover, from the blog Sun Gazing was, “This dog dance was performed at The Open European Championships and totally blew the crowd away.

Trust me, this is going to have you spellbound!

Enjoy!

If anyone can provide the answers to my earlier questions then Dan and I would love to hear from you.
