When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most ...

The second science -- Simple selection -- The genetic and ecological context of selection -- History, chance, and necessity -- The rate of genetic deterioration -- The rate of environmental ...

Study of 280 empirical papers suggests evolution is shaped by both individual advantage and competition between groups.

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual selection is where individuals with certain traits have higher reproductive ...

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.

Usually, when someone starts talking about the interface between evolution and physics, it’s a prelude to a terrible argument that attempts to claim that evolution can’t possibly happen. So, ...

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex. Thousands of miles from home in ...
