Genetic Time Capsule: South Carolina Man’s DNA Shows Male Ancestor 338,000 Years Ago

130305-coslog-ychrom-440p.photoblog600220px-NeanderthalensisA South Carolina man, Albert Perry, recently died and one of his relatives decided to submit a DNA sample to a company called Family Tree DNA to help detail their genealogical tree. The company however was confused because his Y-chromosome did not appear in his family tree. Later analysis by Michael Hammer, a geneticist at the University of Arizona in Tucson, found that Perry’s Y chromosome showed that his male lineage probably separated from all others about 338,000 years ago. Before Perry, all men could be traced to a genetic “Adam” who lived between 60,000 and 140,000 years ago. Now we have a man with a link that goes back almost 200,000 years earlier. Of course, that does not quite fit with creationists who believe the Earth is only 5000 to 6000 years old, but for the rest of humanity it is a pretty interesting discovery.

The results of this research were published recently in a study by the The American Society of Human Genetics.

Perry’s chromosome shows that the last common male ancestor down the paternal line of our species is over twice as old as we thought. The chromosome is a type of genetic time capsule that may reflect the interbreeding between Neanderthals and Denisovans. Hammer’s team looked at an African database of nearly 6000 Y chromosomes and found similarities between Perry’s and those in samples taken from 11 men, all living in one village in Cameroon. That may be the very village that Perry’s ancestors came from.

That is very cool.

  1. I would like to comment on the religious part as well. Creationism, Darwinism or in between, if this man’s research is brave enough to be published, it must be scrutinized and studied. Therefore, if you want to have an educated opinion, educate yourself before you give it. FIND his research and try to recreate it OR find the flaws by learning his methods. Too many people offer there opinion against science who are not scientist.

  2. How did the incredible research and discoveries of human DNA and its linkage to our enigmatic biology and human history turn into a fight about one psycho guy? Why not give these brilliant people their credit and let this not be another part of this seemingly endless political debate?
