Evolvability: The race against extinction

By Bryan Moyers

It’s easy to think that evolution only works over long periods of time.  As much as 4.1 billion years ago, life began on Earth.  Some 420 million years ago, animals found their way onto land.

April is a natural fit for Stress Awareness Month, playing host to inevitable final exams and tax season. But is there a way to avoid the stress that comes along with them?
