A hurricane cleared Bahamian islands, offering scientists a rare chance to observe evolution beginning anew. Researchers ...

Much change is due to random genetic drift rather than positive selection. It could be called the survival of the luckiest. You might think that largely neutral mutations would remain restricted to a ...

“Where are all the genetic cures?” asks Denis Noble, a frustrated biophysicist, Royal Society fellow and pioneer of the field of systems biology. “They don’t exist. Where will they be? They won’t ...

Here’s what you’ll learn when you read this story: In the 1960s, Kimura’s neutral theory revolutionized molecular biology by arguing most DNA changes are random, not adaptive. A new study finds ...
