In a region where modern humans are believed to have originated roughly 200,000 years ago,    DNA from the skeleton of a man who lived 2,330 years ago has a DNA profile that places it…

Astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space -  27,000 light years away. Like finding a…

A key indicator of how successfully one species of monkey will breed can be determined by skin color, a new study has shown. Skin coloration in male and female rhesus macaques is an inherited…

So much for patriarchy. When it comes to evolution, female populations have always been larger than male populations throughout human history, according to a new study in Investigative Genetics which…

A new study uses tree rings to document arroyo evolution along the lower Rio Puerco and Chaco Wash in northern New Mexico. Arroyos are deep, oversized channels that have vertical or steeply cut walls…

Parasitic lamprey are a challenge to study but an important one - they are an invasive pest in the Great Lakes but difficult to study under controlled conditions because they live up to 10 years and…

"Ontogeny recapitulates phylogeny" biologists once said - meaning that an animal's "ontogeny", its embryonic development, replays its entire evolutionary history. Today our understanding a more…
