The study of evolution requires consideration of organisms’ microbiomes.

The findings of a new study contradict previous results from some of the same scientists that suggested Neanderthal DNA was gradually removed from modern human genomes.

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

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

A study of five far-flung human populations gives clues to adaptations to environmental pressures.

The turtle-headed sea snake is losing its stripes, and researchers suggest that the change reflects adaptation to fouled oceans.

Natural selection may be behind the dearth of Neanderthal DNA in modern humans.

Some thoughts on going to the Galápagos

The emergence of blood abnormalities, an adult ability to digest milk, and changes in our physical appearance point to the continued evolution of the human race.
