Why did humans domesticate dogs in the first place? A new study shows that humans may have done this because they needed to share their meat.
“Humans are not fully adapted to a carnivorous diet; human consumption of meat is limited by the liver’s capacity to metabolize protein,” says the study. “Contrary to humans, wolves can thrive on lean meat for months.”
The theory goes that humans shared their meat with wolves and the wolves kept coming round and became “docile, being utilized in a multitude of ways such as hunting companions, beasts of burden and guards as well as going through many similar evolutionary changes as humans.”
This pokes some holes in the paleo diet theory that our ancestors lived on mostly meat.
