When we think of lead poisoning, most of us imagine modern human-made pollution, paint, old pipes, or exhaust fumes.

The Organismic and Evolutionary Biology professor sat down with Fifteen Minutes to discuss fruit flies, puzzles, and LS50.

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

The study of Astyanax mexicanus, encompassing both its cave-adapted and surface-dwelling forms, has emerged as a model for understanding evolutionary adaptation to extreme environments. Researchers ...

What appears to be a cozy bedtime for a baby monkey is actually a living experiment in evolutionary biology. The ritualized ...

An international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The ...

The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...

As wildfires become more common and more severe, habitats that are burned become even hotter. The study found that in areas ...
