One key character in my novel The Stone-Age Detective is a dog.
I hope you have read my blog about my prehistoric detective novel. Even if you like what I say there, you may think everything I say about the dog in the novel is pure fiction, fantasy even. Well, I have found, to my surprise, how much scientists think they know about Stone-Age dogs. They have studied DNA from skeletons to establish that the ancestors of dogs were wolves, but by the end of the Ice Age they were two separate species. Dogs were generally similar to but smaller than wolves.
What colour were dogs in the Stone-Age?
The obvious answer is ‘we don’t know’, but there is a clue. A few years ago, Russian scientists experimented with selective breeding arctic foxes, to see how long it took to turn a fierce wild animal into a suitable pet. Not many generations. They found, unexpectedly, that the tamest ones were also different in other ways from their wild ancestors. In particular, they found the tame foxes were more often two-coloured. At first, white socks and tail tips appeared, but later some were 50/50. The scientists believe the colour element in the animals’ DNA is linked to the element affecting temperament.
Wouldn’t Stone-Age Man have preferred plain dogs?
As in my novel, many people probably thought plain dogs were better at hunting, but some would have liked more conspicuous canine hunters, because the prey moved away from them towards waiting humans. This phenomenon probably led to the development of the use of dogs for rounding-up domestic livestock. That is perhaps why most sheepdogs are black and white.
Could a dog climb trees?
Most dogs don’t. Whether they could, is another matter. I once owned one who did, usually when chasing squirrels. She didn’t often catch them. I gave my fictional Stone-Age dog that ability to add something to the story.
