A study published in Scientific Reports strongly supports the hypothesis that humans who fed wolves’ leftover meat during harsh winters had a role in the early domestication of animals. dogs, near the end of the last ice age, between 14,000 and 29,000 years ago.
Humans and lobos they hunted large prey in herds and in fact represented a competition for the same resources, this could lead them to kill each other; For this reason, the question that needs to be answered is why did humans end up domesticating a competitive species?
European and American experts, led by Marian Lahtien of the Finnish Food Authority, believe that late Pleistocene hunter-gatherers in Eurasia will have a surplus of protein derived from their prey that they would have shared with the former. lobos captured, thus reducing competition for prey.
These surpluses would be produced because all species of prey would have provided more protein than humans could eat. And this is the key point of evolution in the company of another species, since the consumption of proteins by humans was limited by the ability of the liver to metabolize them.
Humans may have had an animal-based diet during winters, when plant foods were limited. However, it is certain that they were not suited to a protein-only diet and preferred the consumption of high-fat meat over lean, high-protein meat.
The lobosThey can survive on a diet containing only protein for months, so humans may have fed wolves excess lean meat; giving birth to an ancestral society between dogs and humans.
Feeding the wolves would have facilitated cohabitation with the captured wolves, would have made them more docile and favored their use as hunting aid and guardians, thus initiating the process of domestication of the wolf. dog.
