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 ...

Tree genome evolution is a fascinating area in the study of biodiversity and ecosystem stability. Trees, with their distinctive life history traits, such as ...

Part One. The basics of population genetics -- Part Two. Complex genetic systems -- Part Three. Special topics in evolution -- Part Four. Evolutionary ecology of single populations -- Part Five.

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 ...

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

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.

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 ...

Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of ...

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