A new study published this week shows a genetic 'battle of the sexes' could be much harder to resolve and even more important to evolution than previously thought.
New research has found that a genetic variant which reduces the chance of contracting diseases such as tuberculosis and leprosy is more prevalent in populations with long histories of urban living.
Using digital evolution techniques that give scientists the ability to watch evolution in action, Michigan State University researchers have shed new light on what it is that makes species altruistic.
Scientists at Harvard University have sketched a new map of the "evolutionary labyrinth" species must traverse to reach eusociality, the rare but spectacularly successful social structure where individuals cooperate to raise offspring.
Mothers win the genetic tug of war by producing more sons with larger fathers and more daughters with smaller fathers.
