In the U.S., it's easy – and fairly inexpensive – to send one's DNA away for testing to learn more about one's ancestry, disease predisposition, and traits. I know that at least one company (23andMe) tests for Neanderthal DNA. It's incredible that technological advances have made so much information available to us. Of course, there are differing perspectives on whether or not getting one's DNA tested is worthwhile, wise, etc.

I suspect many people have only a basic understanding of how DNA testing this works and what the connection is between evolution and genetics (how can a modern human have Neanderthal DNA?). For the biology or genomics lovers out there, how would you answer the question: How are genetics and evolution related?
