Dogs were probably domesticated by accident, when wolves began trailing ancient hunter-gatherers to snack on their garbage. Docile wolves may have been slipped extra food scraps, the theory goes, so they survived better, and passed on their genes. Eventually, these friendly wolves evolved into dogs. 18 июл. 2017 г.
What's the evolution of a dog?
The dog, Canis familiaris, is a direct descendent of the gray wolf, Canis lupus: In other words, dogs as we know them are domesticated wolves. Not only their behavior changed; domestic dogs are different in form from wolves, mainly smaller and with shorter muzzles and smaller teeth.
How a dog was created?
Dogs most probably evolved from wolves at a single location about 20,000 to 40,000 years ago, a study suggests. Previously, it had been thought that dogs were tamed from two populations of wolves living thousands of miles apart.
How did humans evolve dogs?
Dogs are thought to have evolved from wolves that ventured into human camps, perhaps sniffing around for food. As they were tamed, they could then have served humans as hunting companions or guards. The results suggest all dogs derive from a single extinct wolf population - or perhaps a few very closely related ones.
What pattern of evolution does dog represent?
Parallel evolution This fact can be used to study the coevolution of gene function. Dogs accompanied humans when they first migrated into new environments. Both dogs and humans have adapted to different environmental conditions, with their genomes showing parallel evolution.
