Summary: Researchers found that Italian brown bears living near humans evolved unique genetic and behavioral traits. The ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Researchers find Apennine brown bears evolved into a smaller, less aggressive animal after centuries of coexistence with ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

Professor Graham Coop, Department of Evolution and Ecology and Director of the Center for Population Biology, has been elected as a Fellow of the American Academy of Arts and Sciences for his work on ...

A lost chapter in human evolution has been revealed after an analysis of modern DNA found that we come from not one but two ancestral populations—ones that drifted apart and later reconnected long ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
