Humans feeding leftover lean meat to wolves during harsh winters may well have had a purpose in the early domestication of pet dogs, in direction of the stop of the previous ice age (14,000 to 29,000 many years back), in accordance to a review published in Scientific Experiences.
Maria Lahtinen and colleagues utilised straightforward electrical power written content calculations to estimate how a great deal strength would have been remaining about by individuals from the meat of species they may possibly have hunted 14,000 to 29,000 several years that ended up also common wolf prey species, this kind of as horses, moose and deer. The authors hypothesized that if wolves and individuals had hunted the identical animals through harsh winters, people would have killed wolves to reduce level of competition somewhat than domesticate them. With the exception of Mustelids these kinds of as weasels, the authors discovered that all prey species would have provided more protein than human beings could take in, resulting in excessive lean meat that could be fed to wolves, therefore lowering the opposition for prey.
Although people might have relied on an animal-based eating plan through winters when plant-based mostly foodstuff were confined, they had been possibly not adapted to an solely protein-centered diet plan and could have favoured meat loaded in excess fat and grease around lean, protein-abundant meat. As wolves can survive on a solely protein-centered diet plan for months, humans may have fed surplus lean meat to pet wolves, which may have enabled companionship even for the duration of severe winter season months. Feeding excessive meat to wolves could have facilitated co-living with captured wolves and the use of pet wolves as looking aids and guards could have further more facilitated the domestication process, eventually to entire canine domestication.
