Urban environments are driving genetic changes in resident species through multiple mechanisms, from establishing gene flow barriers to exerting novel selection pressures.

From changes in gene flow to adaptation, the effects of urbanization are shaping the evolutionary trajectories of plants and animals.

The pelvic bones of women have been shaped more by random evolution than by natural selection, a new study finds.

A new study sheds light on how the most abundant bird in North America went extinct. 

No two neurons are alike. What does that mean for brain function?

Researchers are abandoning the concept of a list of genes sequenced from a single individual, instead aiming for a way to describe all the genetic variation within a species.

To make sense of the genetic variation within species, researchers are turning to the concept of the pangenome.

Mammals and amphibians show greater intraspecific genetic diversity in the tropics compared with temperate regions.

Female fruit flies challenged with infection during their lifetimes have offspring with greater genetic diversity.
