David Rand, a professor of natural history at Brown University, explains how studying mitochondria — the cell's energy producers — offers a useful way to understand complex gene-by-gene or ...

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 ...

Millions thrive at high altitudes due to remarkable genetic adaptations. Tibetans, for instance, possess a gene variant allowing efficient oxygen use without dangerously thick blood. Andeans and ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long ...

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

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 ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

When a nuclear disaster empties a landscape of people, nature doesn’t politely wait for instructions. It moves in. After the ...
