Who Invented the Dog?
6th in a #ReadWithMe series.
When you look at your dog, you seldom thing it is “a crucial innovation”. Yet dogs were. We have difficulties even conceiving that somebody, at a certain point, thought about domesticating them, as we are so used to having them on our side. Yet somebody, at some point, did.
The domestication of dogs happened between 20,000 and 40,00 years ago.
It is likely, writes Matt Ridley, “that the domestication began with wolves tentatively hanging around human camps to try to scavenge leftover carcasses. The bolder ones risked being speared, but got more food; gradually boldness in the presence of people became commoner in one group of wolves till people saw the advantage of having semi-tame wolves hanging around”.
Ridley knows that “it is stretching it to call domestication genetics an innovation”, particularly when the view widens to include the way in which we human beings domesticated: we are dogs to our wolves ancestors. Though it is not clear which genes accomplished the result, some kind of selection took place, changing us profoundly, in a way fitter to a far more gentle, less violent and rumbustious life.
In closing his chapter on the invention of the dog, Ridley makes one of the key points of his book in a very clear way: “Innovation is a lot less directed and planned, even today, than we tend to think. Most innovation consists of the non-random retention of variations in design”.
