Question:

Has anyone signed up for the National Geographic Genographic project? Is it worth $100?

Best Answer - Chosen by Asker: I signed up for it, and it was a bit expensive for me, but I found it to be worth it. You only find out where your distant ancestors lived about 10,000 years ago, but that was very interesting for me. It's a better value if you are a male because males have traceable markers on both X and Y chromosomes; females only have the X chromosome to work with so they won't get any information about their fathers' lines.
Still it's a contribution to research.
