Domesticated wheat has complex parentage

Certain types of domesticated wheat have complicated origins, with genetic contributions from wild and cultivated wheat populations on opposite sides of the Fertile Crescent. Terence Brown and colleagues at the University ...

Origin story: Rewriting human history through DNA

For most of our evolutionary history—for most of the time anatomically modern humans have been on Earth—we've shared the planet with other species of humans. It's only been in the last 30,000 years, the mere blink of ...

Specific immune response of beetles adapts to bacteria

The immune system fends off pathogens in a wide variety of ways. For example, the immune system's memory is able to distinguish a foreign protein it has encountered before and to react with a corresponding antibody. Researchers ...

When plant roots learned to follow gravity

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The how and when of this evolutionary step has, until now, remained unknown. Plant biologists at the Institute of Science and ...

Hidden genetic variations power evolutionary leaps

Laboratory populations that quietly amass 'cryptic' genetic variants are capable of surprising evolutionary leaps, according to a paper in the July 26 issue of Science. A better understanding of cryptic variation may improve ...

Software to protect the world's most endangered species

By combining genetic and environmental databases, researchers at EPFL are seeking to help biologists identify more accurately the animal and plant species most exposed to climate change, in order to develop appropriate conservation ...
