A reminder of very ancient times.

The positives and negatives of dogs being dogs.

It is our routine at home here in Oregon to let the kitchen group of dogs out first (Lily, Ruby, Casey & Paloma, with Sweeny tagging along) while Jean puts together our small breakfast.  The time is around 6am to 6:30am and both Jean and I are usually wearing dressing gowns.  Once this first group has been outside, then I let the ‘bedroom’ group out (Pharaoh, Cleo, Hazel and Dhalia).

Such as I did this morning, unusually a day starting dull with overcast cloud.

Suddenly, I heard the most awful squealing of an animal in pain over in the dense wooded area to the South-West of the property.

The wooded area in question.
The wooded area in question.

In plastic slippers and dressing-gown only, I dashed into the woods and to my horror saw that Cleo, Hazel and Dhalia had cornered a young deer, and at least Hazel was nipping at a rear leg.

A not uncommon sight at home.
A not uncommon sight at home.

I screamed at the dogs, to no avail.  They took not the slightest notice of me.

Then the young deer wriggled free and fled into the trees.  The dogs recornered it and plunged in again.  The deer broke free again, and so it went on.  Eventually, after some ten minutes of the most dreadful hollering and chasing by me, the young deer jumped a fence and ran off with its mother who had been shadowing the terrible event.  I prayed that it wasn’t badly hurt.

Gracious, I was so angry with the dogs!  What disgusting behaviour towards this young, beautiful creature.

When I was back in the house trying to regain my breath, still so angry at the dogs, a thought came to my mind.  Tens of thousands of years ago, this behaviour of the dogs was held in great esteem.

Early man evolved from a tribal hunter-gatherer existence to the pastoral life of farming about 10,000 years ago.  If the DNA evidence shows, as it does, that the dog evolved from the wolf as a separate species around 100,000 years ago, then dogs were part of the life of hunter-gatherer man for something of the order of 90,000 years, possibly a couple of decades longer!

In fairness, the present lineage of dogs was domesticated from grey wolves only about 15,000 years ago. Despite fossil remains of domesticated dogs having been found in Siberia and Belgium from about 33,000 years ago, none of those lineages survived the Last Glacial Maximum. No fossil specimens prior to 33,000 years ago have indicated that they are clearly from the morphologically domesticated dog.

Even if, and it’s a very big ‘if’, the relationship between man and dog is only about 15,000 years old, one can only speculate how each species came to know the other, in every imaginable way.

Actually, we can go beyond speculation because in a study published by the PLOS ONE scientific journal in March 2013, Dr. Robert Losey, Associate Professor in the Department of Anthropology, University of Alberta and the lead author, explained that:

Dog burials appear to be more common in areas where diets were rich in aquatic foods because these same areas also appear to have had the densest human populations and the most cemeteries,

If the practice of burying dogs was solely related to their importance in procuring terrestrial game, we would expect to see them in the Early Holocene (around 9,000 years ago), when human subsistence practices were focused on these animals. Further, we would expect to see them in later periods in areas where fish were never really major components of the diet and deer were the primary focus, but they are rare or absent in these regions.

The PLOS ONE paper went on to report that researchers found that most of the dog burials occurred during the Early Neolithic period, some 7,000-8,000 years ago, and that “dogs were only buried when human hunter-gatherers were also being buried.

So back to the morning’s drama between the dogs and the young deer.

The efficiency of the way the dogs cornered the deer was breath-taking.  Had I not been coming at them in such a state of anger and agitation, and especially if I was one of a group of say, 2 or 3 humans, the odds are that the deer could have been grabbed and dispatched.  In other words, those three dogs had demonstrated that 20,000, 40,000, 80,000 or more years ago, they were critically useful at helping early hunter-gatherer man feed himself.

Back to Dr. Losey’s view, “I think the hunter-gatherers here saw some of their dogs as being nearly the same as themselves, even at a spiritual level. At this time, dogs were the only animals living closely with humans, and they were likely known at an individual level, far more so than any other animal people encountered. People came to know them as unique, special individuals.

Does make sense, doesn’t it.

Dogs and Man: an eternity of a relationship

New research shows the beauty of the bond between dog and man.

I was doing some research for another writing project and came across this on the NBC News website:

What prehistoric dog burials tell us about owners

By Jennifer Viegas

An analysis of ancient dog burials finds that the typical prehistoric dog owner ate a lot of seafood, had spiritual beliefs, and wore jewelry that sometimes wound up on the dog.

The study, published in PLoS ONE, is one of the first to directly test if there was a clear relationship between the practice of dog burial and human behaviors. The answer is yes.

Ancient DNA Analysis Affirms the Canid from Altai as a Primitive Dog

Abstract

The origin of domestic dogs remains controversial, with genetic data indicating a separation between modern dogs and wolves in the Late Pleistocene. However, only a few dog-like fossils are found prior to the Last Glacial Maximum, and it is widely accepted that the dog domestication predates the beginning of agriculture about 10,000 years ago. In order to evaluate the genetic relationship of one of the oldest dogs, we have isolated ancient DNA from the recently described putative 33,000-year old Pleistocene dog from Altai and analysed 413 nucleotides of the mitochondrial control region. Our analyses reveal that the unique haplotype of the Altai dog is more closely related to modern dogs and prehistoric New World canids than it is to contemporary wolves. Further genetic analyses of ancient canids may reveal a more exact date and centre of domestication.

DNA testing indicates that the evolutionary split between dogs and wolves was around 100,000 years ago or more. The value of dogs to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures.

Thus it is in the order of 90,000 years, possibly a couple of decades longer, from the point where a bond was made between early man and the wolf to the era when man evolved from a tribal hunter-gatherer existence to farming the resources of the planet. Thousands and thousands of years of dogs being the greatest animal relationship we humans have ever experienced.

Back to that NBC news item:

Erik Axelsson, a researcher at Uppsala University’s Science for Life Laboratory, has also studied prehistoric dogs. He too found that human and dog diets, burial practices and more often paralleled each other, revealing how close the dog-human bond has been for thousands of years.

Axelsson said, “Dogs and humans share the same environment, we eat similar food and we get similar diseases.

Based on the number of burials, we also often spend eternity together too.

Eons of time.

A hundred, thousand years of knowing man, and it shows in the eyes.
