Research reveals the impact of environmental changes on genetic variation over time. In a new study, scientists from Arizona ...

Luke is a quantitative geneticist interested in complex trait architecture, and how evolutionary forces such as genetic drift and selection shape that architecture. Starting out in population genetics ...

Find out the different ways scientists have of describing what species are, how they form and how many there are on Earth.

It has been said that the U.S. doesn’t have a healthcare system; rather we have a disease management system—we wait until ...

Fossils found in China and elsewhere show the starts and stops of this evolutionary process throughout the Cretaceous in long ...

Genetic drift: Rare genes are lost over time when random effects determine which genes survive across generations of bison. Random effects occur with each production of ova or sperm and with accidents ...

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 ...

According to this hypothesis, most of the changes in DNA inside individuals are the result of "genetic drift" -- random changes that go on all the time and aren't steered by natural selection in ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...
