美国国家地理学会的遗传学家斯班瑟•威尔斯利用DNA技术经过多方的寻找，终于找到这位人类祖先———科学亚当。今天，他的基因已经遍布于地球上每个男人的身上。

Comparing this Y chromosome to thousands of men from all over the world, reveals a critical discovery. These mutations originating in Africa appear on every Y chromosome in every man in the world today. These are the universal mutations we’ve been looking for. We follow the DNA trail all the way to the bottom of the tree. Every branch leads to one man, one Y chromosome, there must have been one man gave rise to all men alive today. He is the ultimate super ancestor, he is scientific Adam. One of his descendants was M-168. He was the forefather of the ancient Middle Eastern ancestor of Thomas Jefferson. He gave rise to Genghis Khan’s Y chromosome. In fact, all the Y chromosomes in the world trace back to this one African man. He is scientific Adam.

Wales believes the pattern of African Y chromosomes puts his birthplace somewhere in the Great Rift Valley region of / East Africa, perhaps Tanzania or Ethiopia. He thinks this is scientific Adam’s homeland, his Garden of Eden.

Genetics can date the ancient Y chromosome mutations to calculate the age of scientific Adam. Wales believes he was born around 60,000 years ago. It sounds ancient, but it means our search for a common ancestor has not led us all the way back to a time of ape men. Or even to primitive beings like Homo Erectus. Compared to the billions of years of human evolution, we found Adam in the recent past.

The critical discoveries of where and when Adam lived prove he could not have looked like this. For the first time, it’s possible to paint a new portrait of Adam, based on science. Facial reconstructions have shown what other ancient humans might have looked like. We have images of earlier beings, like Homo Erectus, and the ancient pre-human known as Lucy. These faces are all based on fossil skulls, but there are known text ''skulls'' from Adam’s time.
