Team WCG,

IBM and the National Geographic Society are partnering to map our human genetic history. I'm sure this project is of great interest to many WCG participants. Any individual can purchase a DNA testing kit and contribute to this effort. IBMers and National Geographic employees can purchase the kit at a discount.

The below introduction is taken from the Genographic Project website at http://www3.nationalgeographic.com/genographic/ .

The National Geographic Society, IBM, geneticist Spencer Wells, and the Waitt Family Foundation have launched the Genographic Project, a five-year effort to understand the human journey—where we came from and how we got to where we live today. This unprecedented effort will map humanity's genetic journey through the ages.

The fossil record fixes human origins in Africa, but little is known about the great journey that took Homo sapiens to the far reaches of the Earth. How did we, each of us, end up where we are? Why do we appear in such a wide array of different colors and features?

Such questions are even more amazing in light of genetic evidence that we are all related—descended from a common African ancestor who lived only 60,000 years ago.

Though eons have passed, the full story remains clearly written in our genes—if only we can read it. With your help, we can.

When DNA is passed from one generation to the next, most of it is recombined by the processes that give each of us our individuality.

But some parts of the DNA chain remain largely intact through the generations, altered only occasionally by mutations which become "genetic markers." These markers allow geneticists like Spencer Wells to trace our common evolutionary timeline back through the ages.

"The greatest history book ever written," Wells says, "is the one hidden in our DNA."

Different populations carry distinct markers. Following them through the generations reveals a genetic tree on which today's many diverse branches may be followed ever backward to their common African root.

Our genes allow us to chart the ancient human migrations from Africa across the continents. Through one path, we can see living evidence of an ancient African trek, through India, to populate even isolated Australia.

But to fully complete the picture we must greatly expand the pool of genetic samples available from around the world. Time is short.
In a shrinking world, mixing populations are scrambling genetic signals. The key to this puzzle is acquiring genetic samples from the world's remaining indigenous peoples whose ethnic and genetic identities are isolated.

But such distinct peoples, languages, and cultures are quickly vanishing into a 21st century global melting pot.

That's why the Genographic Project has established ten research laboratories around the globe. Scientists are visiting Earth's remote regions in a comprehensive effort to complete the planet's genetic atlas.

But we don't just need genetic information from Inuit and San Bushmen—we need yours as well. If you choose to participate and add your data to the global research database, you'll help to delineate our common genetic tree, giving detailed shape to its many twigs and branches.

Together we can tell the ancient story of our shared human journey.
