Romanian fossils show hominins in Europe 500,000 years earlier than thought
Research led by the Department of Sociology & Anthropology at Ohio University has found evidence of hominin activity at a Romanian fossil site dating to at least 1.95 million years ago. This discovery pushes back the known ...
Being a ladies' man comes at a price for alpha male baboons
A few things come to mind when we imagine the alpha male type. They're the ones calling the shots, who get all the girls. But there's a downside to being a strong and powerful alpha stud—at least if you're a baboon.
