Jesse, Thats the most interesting article I've read in a while. The DNA trail is a topic I've been reading about in Richard Dawkins new books. I disagree with the articles suggestion we might all get along better if we realize we are all related. The Arabs and Hebrew are close biological cousins and they know it. Dawkins took the Darwin approach to evolution with DNA tracking and discovered our species is not related as close as we thought to my Avatar but much closer to racoon. DNA and the double helix are still blowing the top of old ideas and its exciting to see research results but still two people exclaiming 'Aha' looking at the same discovered evidence will think it proves the opposite of the other.
group tried to prove/disprove theory's like the land bridge migration between russia and alaska with blood samples from around the planet about 8 years ago. They sampled blood from almost every group in the world. One outstanding find was a group of people in madagascar that where not related to the rest of the people in the world at any time. A debate rose about them not being homo sapien. Imagine what you could do with that if they got residency in California and wanted to marry a sapien or get government benefits.
