Research Sheds New Light on Process of Evolution:
For more than a century, scientists have concluded that a species evolves or adapts by going through an infinite number of small genetic changes over a long period of time.
However, a team of researchers, including a Michigan State University plant biologist, has provided some new evidence that an alternate theory is actually at work, one in which the process begins with several large mutations before settling down into a series of smaller ones.
Here is the abstract in Nature.
