Here's the intro blurb that comes on the cover of the DNA kit box:
A map, it has been said, is the greatest of all epic poems. There are few greater epics than the story of our distant ancestors leaving their African cradle and colonizing the earth. Thanks to modern genetics we are following their footsteps and charting their migratory paths. Yet much remains unknown. To help complete this map, National Geographic and IBM, with support from the Waitt Family Foundation, are undertaking the Genographic Project, a globe-spanning effort to collect over 100,000 DNA samples representing a worldwide range of human diversity. Broad public participation is encouraged, for it is a genetic journey we all share. Together we may learn more about who we are, where we came from, and how we related as members of one extended family.
My mom did the X-chromosome test and I'm doing the Y-chromosome test, so I'll have maternal and paternal results. I'm hoping it'll explain things such as why my knuckles drag on the ground when I walk, why my forehead is so much larger than other's, and why I feel a deeply seated remorse when I see a hairless elephant.
