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 ...

Physiological traits that help Tibetan women survive at high altitudes are being selected for within the population, meaning they may be becoming more common, new research hints.

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.

Q: Tell us about this "dangerous idea" of Darwin's. A: I think Darwin's idea of natural selection is the best idea anybody ever had, ahead of Newton, ahead of Einstein. What it does is it promises ...

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 ...

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 ...
