The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history. A massive ...

The unexpected discovery of a new type of genetic variation suggests that natural selection -- the force that drives evolution -- is both more powerful and more complex than scientists have thought.

In a recent study, scientists have demonstrated a link between individual variation in risk-taking behavior and survival of animals in changing environments. For more than a century, scientists have ...

As mutation affects essentially every aspect of biology, the development of a unifying theory for mutation-rate evolution is highly desirable. There is much to be explained. For although the ...
