Climate change plus human pressure caused large mammal extinctions in late Pleistocene
...eobiologist Anthony D. Barnosky and his colleagues reached this conclusion after review of studies of the extensive large mammal, or megafauna, extinctions that occurred in the late Pleistocene, when animals such as mammoths and mastodons, the saber-toothed cat, ground sloths and native American horses and c...EMBO Gold Medal 2004 goes to Spanish scientist
