Princeton Scientists Discover Proteins that Control Evolution

Evolutionary changes are supposed to take place gradually and randomly, under pressure from natural selection. But a team of Princeton scientists investigating a group of proteins that help cells burn energy stumbled across evidence that this is not how evolution works. In fact, their discovery could revolutionize the way we understand evolutionary processes. They have evidence that organisms actually have the ability to control their own evolution.
