Individuals feeding leftover lean meat to wolves for the duration of severe winters may possibly have experienced a part in the early domestication of canines, towards the finish of the very last ice age (14,000 to 29,000 yrs back), according to a analyze published in Scientific Experiences.
Maria Lahtinen and colleagues used basic electricity material calculations to estimate how a great deal strength would have been still left about by humans from the meat of species they could have hunted 14,000 to 29,000 several years that ended up also normal wolf prey species, such as horses, moose and deer. The authors hypothesized that if wolves and people had hunted the exact same animals throughout severe winters, people would have killed wolves to cut down competitiveness rather than domesticate them. With the exception of Mustelids this kind of as weasels, the authors uncovered that all prey species would have provided a lot more protein than humans could take in, ensuing in excessive lean meat that could be fed to wolves, hence decreasing the competitors for prey.
Although individuals may possibly have relied on an animal-centered diet regime throughout winters when plant-dependent food items were restricted, they ended up in all probability not tailored to an fully protein-based mostly diet plan and could have favoured meat loaded in extra fat and grease more than lean, protein-wealthy meat. As wolves can endure on a solely protein-dependent diet program for months, people may possibly have fed surplus lean meat to pet wolves, which may have enabled companionship even during severe winter months. Feeding surplus meat to wolves might have facilitated co-dwelling with captured wolves and the use of pet wolves as looking aids and guards may perhaps have even further facilitated the domestication method, ultimately to full puppy domestication.
