History has created a genetic malting part. “And by taking a sample of your DNA, if your genes we can see something about the people you related to in the past, your ancestors.” If the Y chromosomes here lead to a common ancestor for all these ethnic groups, they could lead us to Adam.
“OK, could you open up your mouth?” Wales takes samples from 25 local men. “Great, thank you.” “OK, could you open up your mouth? Where was your mother born?” DNA analysis proves they are Manan party from all over the place. “Thank you.” With ancestors from Africa, Europe, Arabia, India, in the fertile crescent of the Middle East. There is more genetic variation on this tiny island of Patay than in many countries.
And the samples show something critical. They point to a new super ancestor, even though the Y chromosomes come from all over the world. They almost all have something in common. A particular mutation, the scientists call M-168. Infect men all over the planet share this mutation. Genghis Khan and the San Francisco Mongolians have it; Thomas Jefferson has it; Wales himself has it. Nearly three-billion men share this mutation. And it means they are all descended from one man. It’s a stagy thought. Genghis Khan could had fathered millions, but the man who first had this genetically mutation had billions of descendants.
We are near the bottom of the tree. Could this man M-168 be Adam? There is only problem. On the canyon island of Patay, Spenser Wales found one man who doesn’t fit. His Y chromosome doesn’t have the critical mutation. It’s a crusher clone. And his is not the only one. There are others who are not descended from the M-168. So he can’t be Adam. M-168 is far down the tree, but not its base. In the Y chromosome from the other men out on Patay, gives us the final piece of our puzzle.
