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.

Human evolution is far from a relic of the past, as a new study in Behavior Genetics demonstrates. By analyzing data from ...

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes ...

Darwin thought that evolution took place over hundreds or ... The Grants had documented natural selection in action. While beak size is clearly related to feeding strategies, it is also related ...

Evolution happens through natural selection. Darwin was not content to say that organisms evolve. The theory of evolution, he wrote, "even if well founded, would be unsatisfactory until it could ...

Ever since Charles Darwin detailed the mechanism of evolution by means of natural selection in 1859, scientists have had a ...

In fact, it is this facet of natural selection that is easily and massively documented in the DNA record of evolution. “Variations neither useful nor injurious...would be left a fluctuating ...

But there is another, more compelling reason for why life history evolution is important: adaptation by natural selection is based on variation in Darwinian fitness among individuals, and since ...

capable of unlimited evolution through the natural selection of variant forms and combinations most efficient in reproducing themselves. Many biologists believe that life may have originated with ...

A new study reveals that Tibetan communities have developed unique adaptations to survive in the low-oxygen conditions of the ...

It is one of the processes by which species change from generation to generation, and is a crucial element of the theory of evolution. A classic example of natural selection at work is the origin ...
