Climate change plus human pressure caused large mammal extinctions in late Pleistocene
... Barnosky and his colleagues found sparse evidence outside Australia that humans were the sole cause of extinction. Data are sketchy for the Australian continent, Barnosky cautioned, but little climate change was going on at the time of extinction between 40,000 and 50,000 years ago. However, humans were cer...UT Southwestern receives $1.78 million grant for obesity research as part of NIH Roadmap initiative
