Climate change plus human pressure caused large mammal extinctions in late Pleistocene

any large mammals went extinct, since humans arose in concert with these animals and, by some arguments, they should have been in balance with one another. There, as in South America, the uncertainty comes from lack of data. In these fairly recent la...
