The results of the scientific work were published in the journal Nature Communications. As part of the study, experts examined soil samples obtained from Canadian permafrost. Thanks to this material, they were able to deduce DNA that spans the last 30 thousand years in age. Thus, scientists have modeled in detail the communities of prehistoric animals during the transition from the Pleistocene to the Holocene 11-14 thousand years ago. Note that it was then that the representatives of the megafauna began to die out.
Thus, it was found that the population of mammoths and horses tended to decline even before the onset of climatic instability. At the same time, their disappearance was not an unpredictable event due to excessive human hunting. It is reported that the woolly mammoth, as well as the North American horse, still lived in the Yukon about five thousand years ago.
