In this new finding, geneticists say they have identified one of the key changes that turned wolves into the tame, tail-wagging creatures well-suited to living by our sides–the ability to digest carbohydrates with ease.

Carbs were key in wolves’ evolution into dogs. Comparing the DNA of dogs and wolves shows that dogs’ ability to easily digest carbohydrates, originally from starch in scraps left behind by humans, helped enable their domestication, a study finds.

Long ago, some brazen wolves started hanging around human settlements, jump-starting events that ultimately led to today’s domesticated dogs. Now geneticists say they have identified one of the key changes that turned wolves into the tame, tail-wagging creatures well-suited to living by our sides — the ability to digest carbohydrates with ease. By Rosie Mestel
