But before the team could find evidence of natural selection, they first had to rule out allele frequency shifts stemming from genetic drift: random changes in allelic frequency that are more ...

Although the study of natural selection in humans is still in an early stage, the new data, building on decades of earlier work, are beginning to reveal some of the landscape of selection in our ...

As conditions change, so does life. It evolves. Evolution is driven by a process called natural selection. And there's no better place to see how it works than in the forests of Madagascar.

Aa Aa Aa Natural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population ...

Darwin's engine, natural selection, had few supporters: Many people found it distasteful because it seemed to be ruthless and wasteful of life and had no positive, uplifting goal. Some of the ...

How did Natural Selection escape from his shadow and gain acceptance from the scientific establishment? And has any evidence emerged that might challenge the elegant simplicity of Darwin s big idea?
