Have a dog or two in the house? Hide your feelings then!
I have previously remarked on how quickly our dogs pick up on key words and phrases spoken by either Jean or me. In my case, long before I met Jean when I was living in Devon with Pharaoh, I quickly learnt that voicing the word ‘walk’ caused an eruption of interest from his nibs. Then I foiled his intelligence by spelling the word out: w-a-l-k. That lasted all of a fortnight (or two weeks in American speak) before Pharaoh knitted the letters into that walk word.
Here in Oregon our living-room/bedroom group of dogs (Pharaoh, Hazel, Cleo, Sweeney and Oliver) pick up on so many human comments, sayings, and behaviours that at times it feels as though Jean and I need to go somewhere private in order to discuss anything that affects our lovely dogs.
Facial expressions are a key asset in our arsenal of communication methods. Without saying a word, we can alert those around us to our emotional state—ranging from elation to sorrow—simply by flexing a few muscles. Such expressions have evolved to help us connect with one another, avoid danger and work together.
Fellow humans, however, are not the only ones potentially tuning in to the information our expressions convey. According to the results of a study published today in Current Biology, dogs have hacked this silent method of communication, at least enough to distinguish between angry and happy facial expressions.
Dogs and humans share a tight evolutionary bond, which is why veterinarian researchers from the University of Vienna decided to focus on these two species for their study. Dogs are already known to be whizzes at reading us. For instance, they can discriminate between familiar and unfamiliar faces even if just part of the face is shown in a photograph. Whether they actually recognize emotions, however, had not been conclusively investigated before.
It would be wrong to republish the full article without permission but I do want to share another photograph from the article and the closing paragraphs.

Before the authors delve into the greater animal kingdom, though, they plan to further explore their canine findings. Experiments with puppies could lend insight into whether facial expression recognition is something dogs learn over their lives or if it’s something more innate. And trials with wolves could indicate whether human breeders bestowed emotion recognition in their canine companions via artificial selection, or whether that trait was something dogs’ ancient relatives developed on their own simply by living in the vicinity of humans.
While the initial controlled laboratory findings don’t prove that your dog is watching your every facial move for clues about how you are feeling, they do open up the possibility that dogs are even more empathetic best friends than we thought.
Many of you who have dogs in your lives will intuitively know this to be true. But having the scientific underpinning is wonderful confirmation of that truth.
I’m sure I am not alone in having a dog come up to me and lick the tears off my face.
What incredible loving and trusting relationships we have with our dogs.
To underline my last sentence, on a whim I just took the following photograph of Hazel who very rarely isn’t by my side.
Picture taken at 10:35 yesterday morning in my ‘home office’ when I had just finished writing today’s post.
Young Oliver had an upset tummy during the night resulting in the bedroom carpet needing a little ‘sorting out’ after midnight. Thus I was very grateful that a human’s sense of smell is very much inferior to that of the dog!
Oliver sleeping in front of the wood-stove yesterday morning.
I couldn’t escape the irony that today’s post was inspired by an email from friend Dan Gomez. His email included the link to an article on the Brain Links website. It was called How a Dog Actually “Sees” the World Through Smell. Here’s how the article opened:
“The world of scents is at least as rich as the world of sight.”
Even though smell is the most direct of our senses and the 23,040 breaths we take daily drag in a universe of information — from the danger alert of a burning odor to the sweet nostalgia of an emotionally memorable scent — our olfactory powers are not even mediocre compared to a dog’s. The moist, spongy canine nose is merely the gateway into a remarkable master-machine which can detect smells in concentrations one hundred-millionth of what we humans require to smell something, and then transmute them into immensely dimensional and useful information about the world. So magnificent is the dog’s olfactory brawn — including the ability to sniff out skin, breast, bladder, and lung cancers with an astounding degree of accuracy and to literally smell fear — that to our primitive human perception it appears like nothing short of magic.
The article also included this short TED Talk but I have taken the liberty of including the paragraph that preceded the YouTube video.
How that neurobiological magic happens is what cognitive scientist Alexandra Horowitz — who heads the Dog Cognition Lab at Barnard College but has also produced a canon of invaluable insight on how we humans construct our impressions of reality — explains in this short animation from TED-Ed, based on her illuminating book Inside of a Dog: What Dogs See, Smell, and Know (public library):
Mind you, referring back to our overnight doggy incident, I did find one paragraph slightly at odds with my personal views on the subject. It was this one:
We humans tend not to spend a lot of time thinking about smelling. Smells are minor blips in our sensory day compared to the reams of visual information that we take in and obsess over in every moment.
I’m here to tell you that at 1am yesterday morning, my sense of smell was anything other than a minor blip!
OK, before I close, I just want to alert all you dear readers to the fact that from later today until early March my son, Alex, is visiting us. His plans are to find somewhere in Oregon to enjoy some skiing but the very mild Winter so far may put a spanner in those works.
For obvious and natural reasons, writing posts for Learning from Dogs will not be a daily high priority. So if you read a number of posts previously published in earlier times you will understand why. Thank you.
Possibly the most important lesson to be learnt from dogs.
As is the way, a number of separate happenings seemed to be ‘singing from the same song sheet’ in bringing about today’s post.
Earlier yesterday morning Jean and I had a meeting with the executive director of an important charity that is helping the many homeless and disadvantaged young persons in this part of Oregon. For example, Jean and I were told that there were 300-500 homeless teenagers in Josephine County alone (Josephine County is where our home is.)
One of the ideas that was floated in the conversation was how kids are so loving to animals and whether our dogs and horses might help.
Then later, when back home, I recalled that over two years ago I published a post called Sticks and stones.
It wasn’t a long post and is republished now.
oooo
Sticks and stones
I make no apologies for today’s post being more emotional and sentimental. The phrase ‘sticks and stones may break my bones but names will never hurt me‘ is well known throughout the English-speaking world and surprisingly goes back some way. A quick web search found that in the The Christian Recorder of March 1862, there was this comment:
Remember the old adage, ‘Sticks and stones will break my bones, but words will never harm me’. True courage consists in doing what is right, despite the jeers and sneers of our companions.
So if in 1862 the saying was referred to as an ‘old adage’ then it clearly pre-dated 1862 by some degree. A few days ago, Dusty M., here in Payson, AZ, sent me a short YouTube video called The Power of Words. I’m as vulnerable as the next guy to needing being reminded about what’s important in this funny old world.
Then I started mulling over the tendency for all of us to be sucked into a well of doom and gloom. Take my posts on Learning from Dogs over the last couple of days, as an example. There is no question that the world in which we all live is going through some extremely challenging times but anger and negativity is not going to be the answer. As that old reference spelt out so clearly, “True courage consists in doing what is right, despite the jeers and sneers of our companions.” So first watch the video,
then let me close by reminding us all that courage is yet something else we can learn from dogs.
Togo the husky
In 1925, a ravaging case of diphtheria broke out in the isolated Alaskan village of Nome. No plane or ship could get the serum there, so the decision was made for multiple sled dog teams to relay the medicine across the treacherous frozen land. The dog that often gets credit for eventually saving the town is Balto, but he just happened to run the last, 55-mile leg in the race. The sled dog who did the lion’s share of the work was Togo. His journey, fraught with white-out storms, was the longest by 200 miles and included a traverse across perilous Norton Sound — where he saved his team and driver in a courageous swim through ice floes.
More about Togo another day.
oooo
One of the comments left to that post back in November, 2012 was from Virginia Hamilton. Her website, Canine Commandos, is about just that: dogs helping youngsters. This is what Virginia wrote:
Our sermon today was about sticks and stones which is perfect timing because my sixth graders are throwing words at each other and it is hurting. So I looked up the phrase and found you. We were shown the video in a faculty meeting and since you tie into dogs I was hoping to find “the answer.” When you look at the website you’ll see out community project where I have twenty schools training in three shelters. One would think that because these kids are so loving to the animals that they could pass that kindness to each other. Any words of wisdom? Also check this out. Thank you, Virginia.
Now I would be the first to admit that there’s a difference between a homeless young person and a gifted young person. Yet the difference may not be so great. In this one sense: that caring for an animal changes lives and what young people, from all backgrounds and circumstances, need to learn is the power of unconditional love.
Not just caring for dogs, horses and cats, by the way.
The sub-heading was prompted by me doing research for a writing project. I was doing a google search on the history of the relationship between dogs and humans and top of the returns was a post published by Learning from Dogs back in July 2012! Typically, I had forgotten that post. When I clicked on the link and read it right through, it seemed a brilliant idea to republish it today.
oooo
The woof at the Door.
The grandeur of the ancient relationship between dog and man.
A couple of weeks ago, I came across a fascinating article that had been published in American Scientist magazine (online version) written by Professor Pat Shipman. The article provided the background and evidence to support the proposition that dogs may have been man’s best friend for thousands of years longer than we realized.
Very quickly I came across Pat Shipman’s website and learnt that this is one clever lady. As her About page explains,
CAREER SUMMARY
Prof. Shipman
I am internationally known as a paleoanthropologist and conducted research for many years in Africa on human evolution and the animal communities in which humans evolved.
I have conducted research on material from sites in France, Spain, the United States, Java, Ethiopia, Kenya, Tanzania, and South Africa. I have written more than 50 scholarly articles, appearing in journals such as Nature, Science, Journal of Archaeological Science, Paleobiology, Journal of Human Evolution, and Current Anthropology.
I have written more than 100 articles in popular science magazines or newspapers, including The Guardian, The New York Times, The Times Literary Supplement, American Scientist, Discover, and Natural History. Two of my books were featured on the cover of The New York Times Book Review: The Neadertals and Taking Wing. Taking Wing won the Phi Beta Kappa prize for science book of the year and was a runner-up for the LA Times Science Book prize.
My book on Homo erectus, Wisdom of the Bones, was co-authored by Alan Walker and won the Rhone-Poulenc Prize in science writing.
My books have been widely praised as compelling, accessible, and highly readable, with a strong narrative thread. Reviewers frequently comment upon the meticulous research that underpins my books, a feature I consider to be my trademark.
My most recent popular science book, The Ape in the Tree, written with Alan Walker, was called by The Vancouver Sun “part adventure story, part cutting-edge science.” In a Science magazine review, the book was praised as “a fine account of new ways to puzzle out the behaviors of fossilized animals from odd scraps of bone.” Another reviewer raved, “Wonderfully engaging and insightful, The Ape in the Tree, is sure to become a classic in the literature on human origins.” MacArthur fellow John Fleagle wrote in the Quarterly Review of Biology, “Science writing doesn’t get any better than this.” In 2009, this book was awarded the W.W. Howells Book Prize by the American Anthropological Association.
In Britain, my new biography of Mata Hari, Femme Fatale, was selected as The Book of the Week by BBC radio. Each day during the week, an actress gave dramatic readings from the book on the air for fifteen minutes.
With The Animal Connection, I return to paleoanthropology and consider the influence of our connection with animals on human evolution and the origin of modern human behavior.
See what I mean!
Anyway, as you can readily understand, as the author of a blog that writes about what we can learn from this ancient relationship between the dog and man, it struck me as wonderful if I might be permitted to republish in full that article. Prof. Shipman promptly gave me such permission.
So today, I am doing just that and tomorrow I want to write more about Pat Shipman’s latest book, The Animal Connection.
ooOOoo
The Woof at the Door
Dogs may have been man’s best friend for thousands of years longer than we realized
It’s funny how much difference a single letter makes. A “woof” at the door is a very different thing from a wolf at the door. One is familiar, domestic, reassuring; the other is a frightening apparition of imminent danger. The distinction between our fond companions and the ferocious predator of northern climes goes back a long way.
Dogs are descended from wolves, probably the gray wolf. Some scientists argue that, because dogs and wolves can and do interbreed, they shouldn’t be considered to be separate species at all. They believe that domestic dogs are only a subspecies or variant of the gray wolf, Canis lupus, and ought to be called Canis lupus familiaris (the familiar or domestic wolf) instead of Canis familiaris (the familiar or domestic dog). Although the ability to interbreed and produce fertile offspring is a tried-and-true criterion for recognizing that two populations are really variants of a single species, the reality is more nuanced. We cannot know whether dog-wolf hybrids will thrive and survive, or die out, in the long run.
Prehistoric cave paintings rarely depict wolves or other carnivores. This watercolor tracing of a cave painting was made by the archaeologist Abbé Henri Breuil in the early 1900s from the Grotte de Font-de-Gaume in France. The 17,000-year-old cave paintings number about 250 and mostly show bison and mammoths—only one is thought to be a wolf. Canids may have been domesticated by this point; it is possible that portraying wolves and humans was taboo. Paul Bahn
Certainly we expect to be able to distinguish a dog from a wolf if we see one. Of course, domestic dogs are wildly variable in size and shape, thanks to several hundred years of selective breeding. Some have long, fluffy coats; others have tightly curled, nearly waterproof coats and webbed feet. Some are leggy and swift, whereas others are solid, stoutly built guard dogs. Some fit neatly into a pocketbook, but others barely fit into a compact car. As Robert K. Wayne of the University of California at Los Angeles declares, “Dogs show more diversity in appearance than any other mammal.”
What is it that tells us this animal is “dog” and that one is “wolf?”
Modern wolves and dogs can be distinguished reasonably easily by their appearance. The most telling feature of dogs is the snout, which is significantly shorter and wider than wolves’ snouts. Only a few dog breeds with extremely elongated, slender snouts, such as Irish wolfhounds, surpass wolves in “snoutiness.”
But a crucial part of the difference we perceive is in the animals’ manner and attitude towards humans. Domesticated dogs are just that: canids that live in the house or domicile of humans. They are genetically disposed to seek out human attention and approval and to accept human leadership. Wolves are not.
How did this important change come about? Probably in the distant past, humans took in a wolf cub, or even a whole litter of cubs, and provided shelter, food and protection. As the adopted cubs matured, some were aggressive, ferocious and difficult to handle; those probably ended up in the pot or were cast out. The ones that were more accepting of and more agreeable to humans were kept around longer and fed more. In time, humans might have co-opted the natural abilities of canids, using the dogs’ keen noses and swift running skills, for example, to assist in hunting game. If only the most desirable dogs were permitted to breed, the genes encoding for “better” dogs would continue to be concentrated until the new domesticated species (or subspecies) was formed.
Time to Tame
The creation of a domestic, useful, familiar canid by years of selectively breeding wild and terrifying wolves was almost certainly unplanned. The wolf at the beginning of the process of domestication was tamed—made individually docile—but the essential fact is that, over time, the offspring of those initial wolves were genetically inclined to be more tractable.
Domestication was one of the most brilliant accidents in the entire history of humankind. What’s more, we got it right the first time: Dogs were the original trial animal, and successful product, of such an accident—the happy outcome of years of unwitting experiments and dumb luck.
How long does domestication take? Nobody knows. In an experiment, Russian biologists kept a breeding colony of silver foxes and intentionally selected for breeding those with the least fear and the least aggression toward humans. After 10 generations, 18 percent of the foxes sought human contact and showed little fear. After 30 or so generations, a “domesticated fox” had been created.
The catch is that this experiment was deliberate and strictly controlled. The foxes could not breed with wild foxes and dilute the changing gene pool. Human contact was minimized so animals could not be tamed by their handlers. And because of the experiment’s scientific intent, no one could say, “Oh this one is so cute, let’s let it breed even if it is a little aggressive.” So in the case of dogs, without all these controls, the process could have taken much longer.
Another way of estimating the time at which domestic dogs originated is to consider their genetic differences from wolves. One prominent group of researchers, including Robert Wayne, along with Carles Vilà of the Uppsala University in Sweden and their collaborators, initially estimated in 1997 that dogs diverged from gray wolves 100,000 to 135,000 years ago. After more study, they revised their divergence date to between 40,000 and 100,000 years ago. Another group, led by Peter Savolainen of the Royal Institute of Technology in Sweden, favored the Chinese wolf, a subspecies of the gray wolf, as the probable ancestor and estimated in 2002 that it was domesticated between 15,000 and 40,000 years ago.
How do these genetic estimates stack up against the fossil record? Until 2009, the oldest known remains of domestic dogs were two adult skulls dated to between 13,000 and 17,000 years ago, from Eliseevichi, a region in Russia. Both had the relatively broad, short snout typical of dogs, and both were large, heavy animals, nearly the size of great Danes.
Then a team led by Mietje Germonpré of the Royal Belgian Institute of Natural Sciences reported a stunning new finding in the February 2009 issue of Journal of Archaeological Science: a nearly complete fossil dog skull dated to 31,680 + 250 years ago.
Another Look
Germonpré and her colleagues thought that researchers might have overlooked early prehistoric dogs in the fossil record of the Upper Paleolithic, so they analyzed skulls of large canids (wolves or dogs) from various European sites. The Upper Paleolithic time period spanned 40,000 to 10,000 years ago and is divided into sections based on the artifacts from those times. By convention, each span is named for a culture of people who made the artifacts, and the people, in turn, are usually named for the geographical location where the artifacts were found. The Epigravettian culture existed from 14,000 to 10,000 years ago; before that, the Magdalenian culture thrived from 18,000 to 10,000 years ago; and skipping back a few sections, the Aurignacian culture occurred from 32,000 to 26,000 years ago.
In order to identify the fossil skulls accurately, Germonpré’s team first analyzed a large reference sample of 48 wild, modern wolves and 53 dogs belonging to 11 different breeds. They also examined five skulls (including the ones found in Eliseevichi) that were firmly established as prehistoric domesticated dogs.
In order to establish the morphological differences between wolves and dogs, a group of researchers led by Mietje Germonpré statistically analyzed skulls from 48 modern, wild wolves and 53 modern dogs from 11 breeds, as well as five skulls that were previously established to be from prehistoric dogs. Recent wolves (pink) and prehistoric dogs (blue) clustered into their own groups, based on the length of their toothrows and the shape of their snouts. Modern dogs clustered into four groups, with some overlap in their areas. Recent dogs with archaic proportions included huskies (brown), recent dogs with wolflike snouts included German shepherds (yellow), recent dogs with short toothrows included great Danes (orange), and recent dogs with slender snouts included doberman pinscers (green). One modern dog, a Central Asian shepherd, clustered with the prehistoric dogs. The group then classified new skulls into the established groupings; examples that fell slightly outside of the ranges but that are statistically likely to be within the group are shown as lighter-shaded areas. Recent young wolves fell into the recent-wolf group, whereas wolves kept in captivity were classifed as recent dogs with wolflike snouts. Fossil canid skulls divided between the recent-wolf group and the prehistoric-dog group, with one falling in the group of recent dogs with wolflike snouts. Stephanie Freese, data courtesy of Mietje Germonpré.
The team used statistical analysis of cranial and dental measurements on the skulls to sort the reference sample into six natural clusters. One cluster contained modern wolves. Another consisted of recent dogs of archaic proportions (such as chow-chows and huskies); a single specimen of a Central Asian shepherd was closer to this group than any other but fell outside it. A third cluster included dogs, such as German shepherds and malinois, which have wolflike proportions. These three groups overlapped each other in their cranial proportions. A fourth group of modern dogs has short toothrows—the length of the jaw that contains teeth—and includes such breeds as great Danes, mastiffs and rottweilers. This group overlapped slightly with the archaic-proportioned dog group but not with the others.
The fifth and sixth clusters were completely separate from all others. One consisted of dogs with extremely long, slender snouts, such as Doberman pinschers. The final group, which had long toothrows and short, broad snouts, was made up of the prehistoric dogs. Statistically, the team’s ability to identify any individual specimen as belonging to the correct group was highly significant and accurate.
Using these clusters as reference categories, Germonpré and colleagues used a statistical technique (called discriminant function analysis ) to assign 17 unknown fossil canid skulls to the established categories. Not all of the “unknowns” were truly unknown, however. Five were immature modern wolves that might have had different proportions because of their age, two were wolves that had been kept in captivity, and one was the Central Asian shepherd that didn’t cluster into any of the groups. Additional unknowns were 11 fossil skulls from sites in Belgium, the Ukraine and Russia, although two of these fossil skulls proved to be too incomplete to classify.
The technique correctly classified all of the immature wolves as wolves, but the two zoo wolves were classified as recent dogs with wolflike snouts. Five of the fossil skulls also fell easily into the modern wolf group; although two of these specimens fell into the region of measurements that overlapped with the group of recent dogs with wolflike snouts, they had a higher statistical probability of being wolves. One fossil skull fit directly into the group of recent dogs with wolflike snouts, even though this specimen was clearly ancient.
The remaining three fossil skulls—one from Goyet Cave in Belgium and one each from Mezin and Mezhirich in the Ukraine—resembled each other closely. All three were classified as prehistoric dogs with probabilities of 99 percent, 73 percent and 57 percent, respectively, as was the (modern) Central Asian shepherd, with a 64 percent probability. In addition, the Mezin skull was odd enough in appearance (for a wolf) that another researcher has suggested it might have been a captive wolf. Germonpré and her team were delighted with these results.
The group also successfully extracted mitochondrial DNA (mtDNA) from seven ancient canid bones from Goyet Cave and Trou des Nutons in Belgium. Rather than damage precious skulls, they sampled only bones in which wolves and dogs differ little, so they presumed all of those they sampled for mtDNA were wolves. From each sample, they sequenced a segment of the mtDNA that is highly variable in living wolves and dogs. Each fossil had a unique mtDNA sequence, or haplotype , in this region, which could not be matched with any known sequences for modern wolves (of which there are about 160) or modern dogs (of which more than 1,000 exist) stored in GenBank, a database of all publicly available nucleotide sequences.
“I was not so surprised at the rich genetic diversity of the fossil wolves,” says Germonpré, because there have been other studies with similar findings. Foxes and wolves underwent a severe bottleneck in population size at the end of the last Ice Age, and many genetic lineages went extinct at this time.
“But we were surprised at the antiquity of the Goyet dog,” Germonpré adds. “We expected it would probably be Magdalenian,” perhaps 18,000 to 10,000 years old. This outcome would fit with their results for the Mezin and Mezhirich skulls, which were found with Epigravettian artifacts roughly 14,000 to 10,000 years old. When the age of this specimen from Goyet was directly dated using accelerated mass spectroscopy radiocarbon-dating techniques, the team found that it was not 18,000 years old, but almost twice as old as the next oldest dog, placing the Goyet dog in the Aurignacian period.
A Time of Change
The Goyet dog fossil shows that the domestication of the first animal was roughly contemporaneous with two fascinating developments in Europe.
Around this time, Europeans began producing objects that are recognizable as art. Some of the earliest known art objects from Europe include the remarkable cave paintings of Chauvet Cave in France, the oldest of which were made 32,900 ± 490 years ago. None of the hundreds of glorious Chauvet paintings show wolves. However, the cave preserves something even more haunting: the footprints of a human child about four-and-a-half feet tall, as well as many footprints of large canids and bears.
Around 33,000 years ago, humans began perforating teeth for use in decoration. Although canid teeth made up a very small percentage of the total fauna teeth available, they were used in a majority of the ornaments. Fangs from foxes and wolves appear to have been favorites. One example of a perforated wolf tooth (shown in two views at right) is from Abri Castanet in France and has been dated to 33,000 years ago. A strand of beads interspersed with fox teeth came from the Russian site of Sungir and has been dated to 24,000 years ago (left). There is no specific evidence that canid teeth were used in necklaces; the fox-teeth strand may have been a belt. Randall White
Michel-Alain Garcia of the Centre National de la Recherche Scientifique in Nanterre noticed in 1999 that one track of canid prints appears to accompany the child’s prints. These canid prints, unlike the others, have a shortened middle digit on the front paw: a characteristic of dogs. Garcia suggested that the child and dog might have explored the cave together. Charcoal from a torch the child carried is 26,000 years old.
The Upper Paleolithic cultures of Europe are famous for the flowering of all kinds of exquisite art: sculptures, carvings, paintings and engravings. Animals are common and readily recognizable subjects. Prehistoric art expert Paul Bahn notes that depictions of carnivores, including wolves or dogs, and of humans are rare. Bahn conjectures that portraying wolves and humans might have been taboo.
Anne Pike-Tay of Vassar College offers another perspective. She observes that the scarcity of artistic depictions of carnivores parallels their scarcity in the fossil faunas of the Upper Paleolithic. If domesticated dogs were helping humans hunt, she speculates that they might have been placed in a completely different symbolic category from other animals.
“What if dogs were put in the ‘human family’ category as an extension of the hunter, and like humans, warranted no (or very few) painted or engraved depictions?” she wonders.
The second development of the Aurignacian period is the appearance of objects of personal adornment: jewelry. Although beads and perforated objects occurred much earlier in Africa, the earliest such objects in Europe appeared about 40,000 years ago. At 33,000 years ago, early Aurignacian people began perforating animal teeth (and occasionally human teeth) to wear as pendants or other ornaments, such as belts.
Which teeth did they choose? Among their favorite sources are what have been identified as fangs of foxes and wolves. These identifications might better be termed “small or large canids,” because until now no one has considered the possibility that dogs might have been domesticated so long ago. Besides, identifying a single canid tooth specifically as dog or wolf would be difficult, if not impossible.
Randall White of New York University argues that Aurignacian and later people chose to wear objects that displayed their identity or membership in a certain group or clan. Like gang colors or a t-shirt that proclaims its wearer to be a fan of a particular band, ancient people wore things that made their allegiances clear.
Fossils have helped to establish a far earlier timeframe for dog domestication. A paleolithic canid skull from Goyet in Belgium, about 31,000 years old, has traits characteristic of a dog rather than a wolf (a). When compared to wolves from a similar era, one from Trou Ballu (b) and one from Trou des Nutons (c) in France, the Goyet dog has a relatively wider snout and larger carnassial teeth, and it also has a wider braincase. Elsevier Ltd.
White observes that the teeth Aurignacian people chose to wear were obviously not a random sample of the animals in the fauna. For example, the fauna from the Grotte des Hyènes (Cave of Hyenas) at Brassempouy, France, is dominated by horses, aurochs (a type of cattle) and reindeer—mostly as food remains that often show cutmarks or charring—as well as hyenas, which probably lived in the cave when humans did not. Wolves are rare, making up less than 3 percent of the total fauna. Of approximately 1,600 animal teeth at Brassempouy, only about 2 percent were modified for use as ornaments. However, nearly two-thirds of the ornaments are teeth of wolves or foxes. The rest of the perforated teeth are from other rare species: bear, humans and red deer. None of the teeth of the most common species were used as ornaments at Brassempouy.
Did someone who wore a perforated canid tooth 33,000 years ago proclaim him- or herself to be one of the group that domesticated dogs?
Possibly. Domesticating dogs was a remarkable human achievement that doubtless provided a definite selective advantage to those who accomplished it successfully. They might well have had reason to brag about their accomplishment by wearing canid teeth.

Or, to be more precise, any form of post for today.
The weather forecast for Southern Oregon for yesterday included very significant rain.
They were not wrong.
By the time I sat down to think about Saturday’s post, around 2pm, we had already had 3.2 inches of rain (8.1 cm) and our attention, understandably, was on more important matters, such as the integrity of our driveway bridge over Bummer Creek.
So if you will forgive me, I’ll just offer a few pictures and leave it at that.
Starting with a picture that Jean expressly said I couldn’t publish!
I shall probably be denied access to the bedroom after showing you all how my wife likes to dress up!
What lucky horses to have such a devoted ‘Mum’ that feeds them every morning; whatever the weather.
Only one way in or out: over the bridge!
Neighbours who have been here much longer than us say they haven’t seen so much rain fall in such a short time.
Bummer Creek in full flood – this photograph is of the Creek just 50 yards upstream of the bridge.
This is an old dam for irrigation purposes. One doesn’t want to reflect too long that a cubic yard of water weighs a ton!
Luckily the house (off picture to the right) and immediate surroundings are elevated.
So that’s it for today.
Another picture parade for tomorrow assuming I haven’t been lynched by my lovely wife for showing that earlier photograph.
Yet again, another example of a post almost writing itself.
Let me explain.
Yesterday, I published a post about being sensitive to the world around us.
Then this morning there was a new post from Sue Dreamwalker under the title of Fear of the Future. It was uncharacteristically downbeat for Sue.
Now most who follow me know I try to bring a positive touch within my posts… Yet to be quite honest with you all I am really struggling right now to lift myself from the doldrums of my own thoughts.
The key to conquering our fears lies in awareness. When we identify the irrational thoughts that frighten us and replace them with positive affirming ones.
Argh… all easier said than done..
You would think with my inner Knowing, and my Spiritual mind I should be the last person to take a nose dive into that Pit of depression.. Especially when I dredged its depth before and vowed that I had been there done that and worn the T-shirt and I refuse to wear it again.
I could blame it on my Fall which left me feeling bruised with aching, muscles which are still healing.. And I could blame it on grief as I lost a very beloved Aunt last week. I could blame my fatigue on me deciding to move a whole wall of books out the spare bedroom with wrists still recovering from the sprains of the fall.. And I could blame it on the weather being cold and miserable.. I could even blame it on the state of the world, or the Planets .. I have a whole host of excuses I could fall back upon to justify why I am feeling tired and jaded..
Many left comments including me. I spoke of the reward of hugging a dog. My words included:
I don’t have answers other than to feel what you are feeling. All I hang onto when I spend too much time thinking of my own mortality is that the answer, the answer to the moment, is to bury one’s face into the warm, soft fur of a dog. They seem to sense my need at these times. (And that isn’t meant to sound like me devaluing the love and affection that I receive from Jean!)
In other words, that contact with the warm dog holds me in the present and before long the reinforcement of living that present, loving moment puts the unknown future into perspective.
Another comment was left by blogger Rajagopal that included this wonderful tale:
The only thing that I have seen working in my life is to keep living, as much as possible, in the present. There is nothing to fear, either of the now or of the future.
In this context, wish to leave you with the story of the pregnant deer; in a forest, a pregnant deer is about to give birth. She finds a remote field near a strong-flowing river, that looks like a safe place, as she starts going into labour. At the same moment, dark clouds gather in the sky and streaks of lightning sets off a forest fire. The deer looks to her left and sees an approaching hunter with arrow pointed at her. To her right, the deer spots a hungry lion speeding towards her. What can the pregnant deer do? She is in labour! What will happen? Will the deer survive? Will she give birth to the fawn and will it survive? Or will everything be burnt by the forest fire? Or will she perish to the hunter’s arrow? Or does a horrible end await her at the hands of the hungry lion? Constrained by the fire on one side, the flowing river on the other and boxed in by her natural predators, the deer is apparently left with no option. What does she do? Well, she focuses on delivering and giving birth to a new life.
The sequence of events that follows is the Lightning strikes and blinds the hunter, who releases the arrow which zips past the deer and strikes the hungry lion. It starts to rain heavily and the forest fire is slowly doused by rain water. The deer gives birth to a healthy fawn….In our life too there are moments when we are confronted with negative thoughts and possibilities on all sides, so powerful as to overwhelm us. May be we can learn from the deer. The priority of the deer at that given moment was to give birth as safely as possible.
The rest was not in her hands and any change in her focus would have most likely impeded giving birth to the fawn. In the midst of the severest storm, we just have to maintain presence of mind and do what is in our control…the Cosmic power will take care of the rest…best wishes… Raj.
Finally, there was a recent new follower of this place. Her name is Emma and she writes the blog The Muse in the Mirror. Emma was kind enough to grant me permission to republish a post from last December about the healing power of Llamas. Enjoy!

Llama Loving; The healing power of Llamas
It’s official; I LOVE llamas. There, I said it, put out there for the world to know! I love their gentle, sensitive nature, friendly disposition and most of all their goofy, giggle-worthy expressions, which never fail to bring a smile to my face! Concerned that my llama loving status was bordering on obsession, I was beginning to question whether my love for these comical camelids was founded on anything other than sheer amusement! Thankfully as I researched further my findings confirmed that these beautiful animals are much more than a pretty (funny) face!!!
in USA. The adorable photo’s lay testament to the happiness that llama’s bring to residents at Bellingham Health and Rehabilitation Center in Washington, USA. Llama Marisco (pictured above), and Llama N.H. Flight of the Eagle (pictured right) are trained therapists, who spread comfort and joy as they stop at each bed to kiss the patients or have a hug. Resident Holly Barto remarked that…
“It was heaven. Just emotionally – to be able to touch an animal and hold an animal close.”
Another example of the profound healing benefits of llama’s can be seen in this adorable video below showing Rojo the therapy llama and Napoleon the therapy alpaca from Mtn Peaks Therapy Llamas & Alpacas, in Vancouver, WA USA. A non-profit corporation, which offers therapy teams to visit hospitals and schools in the area. The expressions on people’s faces are heart warming to say the least!
“Who knew such fluffed-up, carrot munching mammals could bring so much joy.”
Laughter is the best medicine.
Llama Dave is disgruntled by the fact I was munching in on his dinner!
If I am having an off day, the first thing I reach for is a funny llama picture. Better still, a visit to the local llama park soon blasts my bad moon into infinity and beyond! A good giggle-fest at the Ashdown Forest Llama park, in East Sussex, dissolves the blues and confirms that laughter really is the best medicine! (See my picture gallery below to see me with some of the residents of the Ashdown Forest Llama park!).
There’s a very good reason behind the saying Laughter is the best medicine. Research suggests that people feel less pain after a good laugh, because it causes the body to release chemicals that act as a natural painkiller. ‘Professor Robin Dunbar of Oxford University, who led the research, believes that uncontrollable laughter releases chemicals called endorphins into the body which, as well as generating mild euphoria, also dull pain.’ (BBC)
It is common knowledge that animals in general make us happier and brighten our spirits. A growing body of scientific research now suggests that interacting with animals can make us not only happier, but healthier too. That helps explain the increasing use of animals for therapeutic purposes in hospitals, hospices, nursing homes, schools, jails and mental institutions.
The use of pets in medical settings actually dates back more than 150 years, says Aubrey Fine, a clinical psychologist and professor at California State Polytechnic University. Fine who has written several books on the human-animal bond says:
“One could even look at Florence Nightingale recognizing that animals provided a level of social support in the institutional care of the mentally ill,”
So there you have it, next time you’re feeling blue, you know what to do! Head on out to your nearest llama park to insight those warm fuzzy feelings from a fluffy four legged llama! Check out my favourite selection of Llama and Alpaca pics below, guaranteed to bring a smile to any face!!

Note: That last photograph above is only one of a wonderful collection of Llama photographs that Emma included in her blog post. Do drop across there and admire all the wonderful pictures.
The incredible healing power of hugging an animal.
One of the blog sites that I subscribe to is Exposing the Big Game. The blog does a fabulous job in exposing the terrible ‘game’ of people hunting animals for sport! Many of the topics that author Jim Robertson exposes are incredibly painful to read but, please, do drop across there and support his efforts.
All of which is a preamble to a short item that was posted last Sunday and is republished here today.
Nothing more to add to those rules than offer this photograph taken at home early one day last December, 2013.
Dearest Suzann, who invited me out to San Carlos, Mexico, for the Christmas of 2007, leading to Jean and me meeting, is heavily involved in rescuing the many feral dogs found in that part of the world.
She recently sent me the following:
Shepherd Boy will be euthanized in a few days at the CA state kennel he is at and Jeannie Wade is trying to help save his life….do you guys know of anyone? Let me know asap.
He is located in the Central Coast area of California and goes by the name ‘Shepherd Boy’ and is one year old.
He is in a high kill shelter and has days to live.
Shepherd Boy is shy and sweet tempered and the volunteers at the shelter feel he will make a very good companion/pet for a nice family or couple.
Paul, If I were up there, I would take him in a heartbeat!
Suzann
Please, please share this as far and wide as possible – urgently.
Shepherd Boy may be found at the Central Coast SPCA, Orcutt, California 93457
Suzann has given me the name of Jeannine Wade and she may be emailed at: centralcoastspca@yahoo.com
A reposting of a blog from Dog Leader Mysteries about a dog food recall.
Quickly stepping over the observation that today’s post is about as far removed, topic wise, from yesterday’s post as one could possibly imagine, nonetheless this is important and needs to be widely shared.

Raw food recall: J J Fuds Frozen Pet Food
J. J. Fuds Raw dog food recall expands
Dear Fellow Dog Lover,
Because you signed up on my website and asked to be notified, I’m sending you this special recall alert.
On January 27, 2015, J. J. Fuds of Valparaiso, Indiana, announced it is expanding its recall of select lots of J. J. Fuds Raw Frozen Pet Food to include 2 other products due to unspecified contamination.
I copied this email notice from The Dog Food Advisor. I highly recommend you sign up for this list.
Please share to save dogs’ lives
We don’t feed Sydney raw meat. We do feed organic raw vegetables in limited quantities. We care about pets and want our readers to share this important news. Also we want you to know that we receive the Dog Food Advisor’s updates. Mike Sagman never stuffs our email box, but sends out notices as fast as he receives them. We asked our local pet stores if they receive notices before opening each day. You can do that. Ask when and how pet foods get pulled from their shelves, your pet’s life depends on this.
As I have mentioned in the past and undoubtedly will do so again in the future, one of the most wonderful aspects of this world of blogging is the way that connections are made. Just a few weeks ago, a connection was made between Learning from Dogs and Dog Leader Mysteries. DLM’s byline is: Saving dogs’ lives and dog lovers’ sanity. Dog Leader Mysteries is written by author Deborah Taylor-French.
Anyway, out of the exchanges that have taken place between Deborah and myself, came a reference to a post about animal happiness that was published on Deborah’s blog in October, 2013. It is very interesting and I am delighted to be given permission to share it with you.

Neuroscience key to animal happiness
“…research in neuroscience has been showing that emotions drive behavior, and my thirty-five years of experience working with animals have shown me that this is true. Emotions come first. You have to go back to the brain to understand animal welfare.”
Animals Make Us Human : Creating the best life for Animals
by Temple Grandin & Catherine Johnson
Water dogs having a blast in Spring Lake Park.
By Deborah Taylor-French
Those of us who live and/or work with animals know…
animals have emotions.
Temple Grandin has made the understanding, care and handling of farm animals her life’s work. I refer to her book Animals Make Us Human because not only has she studied farm animals, but she also loves and lives with pets. In her books, especial this one, she insists that we must understand how animals brains work, how they see, hear and smell every sensory detail in their surroundings.
Animals emotions drive their behavior.
To make a better life for our pets, for domestic and wild animals we must understand the main emotions that drive behavior. This will help us to turn on their positive emotions and avoid turning on FEAR, RAGE and GRIEF.
Example: Rabbits and horses are prey animals.
Never chase either rabbits or horses.
Teach your pet rabbit or horse to come to you.
Always reward them for recognizing their name and coming when called.
When you chase a prey animal, you make him or her fearful of you!
Emotions are the gifts of our ancestors. We have them and so do other animals. We must never forget this. When it comes to animal welfare we can always do better. Most of the time “good welfare” is not “good enough.”
The Emotional Lives of Animals by Marc Bekoff.
Dogs Depend on us for freedom from fear and safety
Never tie up your dog unless it is in your company in a human training session.
A dog needs to feel he can flee to safety.
Be sensitive to your dog’s fear signals and show him you will protect and calm him.
Increase your dogs positive emotions by interesting, but not overstimulating activities.
Always stop training before your dog gets tired.
Dogs are the only animals that live with us inside of their flight zone.
Dogs depend on us for positive and playful lives
When you help increase an animal’s curiosity, you turn on his or her positive emotions of SEEKING and PLAY.
Example: Dogs love to play.
Find a time and place when both you and your dog seem relaxed.
Invite your dog to play by doing a play bow or picking up his favorite toy.
Use an excited and happy tone of voice to call your dog.
Run away.
When your dog chases you, stop.
Wait for your dog to run then chase.
Always stop before your dog seems fearful or overexcited.
Dogs love this game, which dog lovers know dogs play every chance they get.
