Seven things you need to know about evolution

John Hawks is a pretty cool guy. He studies anthropology with a special emphasis on the genetics of human evolution over the past million years or so. Right now he's in Ethiopia looking at fossils. I visited him a year ago at his lab in Madison, Wisconsin.

He written a summary of seven things about evolution. You should read what he has to say to see if you know enough about evolution. Here's a list of the seven things but each one requires a bit of explanation.

1. Evolution is change in a population
2. Evolution is genetic change
3. Many kinds of genetic changes are important to evolution
4. Evolution can be non-random
5. Evolution can be random, too
6. Populations evolve all the time
7. Evolutionary theory has changed a lot since Darwin's day
