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 ...

Glimpses of fatherhood found in non-pair-bonding chimps

Although they have no way of identifying their biological fathers, male chimpanzees form intimate bonds with them, a finding that questions the idea of fatherhood in some of humanity's closest relatives, according to a study ...

Genetic analysis uncovers four species of giraffe, not just one

Up until now, scientists had only recognized a single species of giraffe made up of several subspecies. But, according to the most inclusive genetic analysis of giraffe relationships to date, giraffes actually aren't one ...

Picky ants maintain color polymorphism of bugs they work with

Aphids are tiny bugs that live in large colonies and suck sap from plants, producing a sugar-rich substance called honeydew, which is then eaten by ants. Ants, in turn, protect aphids - in a mutually beneficial relationship ...

Rare evolutionary event detected in the lab

It took nearly a half trillion tries before researchers at The University of Texas at Austin witnessed a rare event and perhaps solved an evolutionary puzzle about how introns, non-coding sequences of DNA located within genes, ...

Ancestors of land plants were wired to make the leap to shore

When the algal ancestor of modern land plants first succeeded in making the transition from aquatic environments to an inhospitable shore 450 million years ago, it changed the world by dramatically altering climate and setting ...
