Brazilian scientists, led by Santa-Elina, have established that people lived with huge laziness and other gigantic animals about 27,000 years ago.
The bones of these prehistoric animals, which present traces of processing, were discovered by archaeologists. The study was published in the journal Proceedings of the Royal Society B (PRSB).
For a long time he dominated the theory of “extinguishing in Pleistocene”, according to which people would have reached the first time on the South American continent about 13,000 years ago and would have rapidly exterminated most large animals. The new data, however, bring essential corrections to these ideas: people appeared there much earlier, and huge lazy, mastodons, tigers with corners, elephants and other species of megafauna have coexisted with man for millennia.
This is confirmed, among other things, by the bone remains discovered in old settlements in Brazil. There are clear traces of intentional processing. From the bones were made tools, weapons and possibly ornaments.
The latest research shows that these gigantic creatures have been 5,000-8,000 years ago. And the traces of prehistoric people are dated between 23,000 and 30,000 years ago. Therefore, they managed to live together for a long time. The main cause of the disappearance of the megafauna, I think the experts, were the climatic changes – the sudden succession of the heating and cooling periods, which disturbed the ecosystems and the trophic chains. Many species of plants and animals have disappeared then, and megafauna failed to adapt.
