A single Neanderthal gene slipped into lab mice triggered unexpected changes in their skeletons. Scientists in Japan uncovered traits echoing long-lost human cousins.

Researchers studied the Kodava people's genetic code and found three genetically distinct ancient subgroups in their timeline ...

A genetic genealogy study by a group of researchers has revealed the ancient origin of Coorgs, which presented an insightful ...

A professor of evolution and ecology at UC Davis has been elected to the American Academy of Arts and Sciences, a prestigious national honor recognizing his contributions to evolutionary genetics.

The relationship between evolution and biology. Ever since the origin of life, evolutionary processes, such as mutation, selection, and genetic drift, are responsible for genetic change in natural and ...

Factors that can lead to genetic changes include mutations in genetic material, natural selection, genetic drift, gene flow, and genetic recombination. Over generations, these processes can lead to ...

Additionally, ancient adaptation signals can be masked by genetic drift—random fluctuations in the frequency ... a graduate student in cell and molecular biology and co-first author on the paper. In ...

The evolution of the White Sands pupfish into two species is unusual in that genetic drift was the driving force. Genetic drift results from the random inheritance of different genes from an ...

One explanation comes from functional biology: introns are thought to be involved in post ... prone to deleterious mutations resulting in more spurious splicing events (drift-barrier hypothesis). To ...

Populations evolve in two primary ways: genetic drift and natural selection. Genetic drift refers to random fluctuations in the frequencies of certain genes between generations in populations.
