People reveal that they have been supreme predators for two million years – a study

A study led by Prof. Ran Barkai and Dr. Mickey Ben-Dor from Tel Aviv University concluded that humans have been top predators for about two million years in an article published in Yearbook of the American Association of Physical AnthropologyThey managed to do this by reconstructing the nutrition of the people of the Stone Age. What exactly did our ancestors eat in those days? Researchers report that they eat mostly meat. They also concluded that at the end of the Stone Age, people gravitated only to vegetables in their diet due to declining animal food sources, forcing them to tame both plants and animals. “Until now, attempts to restore the Stone Age diet have been based largely on comparisons with 20th-century hunter-gatherer societies,”

; Ben-Dor said. “This comparison is in vain, however, because two million years ago hunter-gatherer societies could hunt and consume elephants and other large animals, while today’s hunter-gatherers do not have access to such generosity. The whole ecosystem has changed and conditions cannot. to be compared. “The study also showed that people specifically hunt large and medium-sized animals with high fat content. “Hunting big animals is not an afternoon hobby,” Ben-Dor said. “It requires a lot of knowledge and lions and hyenas achieve these abilities after many years of training. It is clear that the remains of large animals found in countless archaeological sites are the result of the high experience of humans as hunters of large animals.” Many researchers studying the extinction of large animals agree that human hunting has played a major role in this extinction – and there is no better evidence of human specialization in hunting large animals. “Other archaeological evidence – such as the fact that specialized tools for obtaining and processing vegetable foods appeared only in the later stages of human evolution – also support the centrality of large animals in the human diet, for most of human history. . “

“Our study is dealing with a very big controversy at the moment – both scientific and non-scientific,” Barkai said. “Our research is both multidisciplinary and interdisciplinary. We offer a picture that is unprecedented in its inclusion and breadth, which clearly shows that humans were originally supreme predators who specialized in hunting large animals.” As Darwin discovered, the adaptation of species to the production and digestion of their food is a major source of evolutionary change, “he said,” and thus the claim that humans have been supreme predators for most of their development can provide a broad basis for fundamental insights into the biological and cultural evolution of humans.
