People who they fed the wolves lean lean meat through the harsh winters they could have had a position in early domestication of canines, in direction of the top of the final ice age (between 14,000 and 29,000 years in the past), in response to a brand new research revealed within the journal ‘Scientific Experiences’.

Maria Lahtinen of the Finnish Meals Authority and her colleagues used easy vitality content material calculations to estimate how a lot vitality people would have left behind from the meat of species they could have hunted 14,000 to 29,000 years in the past that had been additionally typical prey species. of wolf, reminiscent of horses, elk and deer.

The authors hypothesized that if wolves and people had hunted the identical animals throughout harsh winters, the people would have killed wolves to scale back competitors as an alternative of tame them.

Except for mustelids reminiscent of weasels, the authors discovered that each one prey species would have provided extra protein than people may eat, leading to a extra lean meat that might function meals for wolves, thus decreasing competitors for prey.

Though people could have relied on an animal-based weight loss program throughout winters when plant-based meals had been restricted, they had been most likely not tailored to a completely protein-based weight loss program and will have most popular meat excessive in fats and fats over meat. lean, protein-rich meat.

Since wolves can survive on an completely protein-based weight loss program for months, people could have fed extra lean meat to home wolves, which may have allowed the corporate even through the harsh winter months.

Thus, feeding the wolves with extra meat may haver facilitated coexistence with captured wolves and the usage of these animals as pets and as looking aids and guards could have additional facilitated the domestication course of, and finally the entire domestication of the canine.
