The notoriously difficult downhill MTB portion of the Natural Selection Tour takes place Feb. 15 in Queenstown, New Zealand.

The phrase "survival of the fittest" functions principally in evolutionary theory to describe the biological concept of ...

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 ...

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 theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce.

Today, with access to heretofore unprecedented data sets for the study of human genetic variation, researchers can exploit the genetic signatures of natural selection using novel analytical methods.

A research team led by Durham University has made the surprising discovery that a type of gut bacteria has evolved to use one of their enzymes to perform an important function after death.

The Grants had documented natural selection in action. While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that ...

The time for speculating is over. We now know the roster of the debut Natural Selection Tour (NST) ski event. If you clicked on this article, you came for those names, so we’ll lead there.

Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which ...

Considerable debate still exists bout the precise nature of the mechanisms involved in the process of natural selection. In 23 May Nature, Patrik Nosil and colleagues from Simon Fraser University, ...
