A couple of days ago I watched a very interesting documentary on National Geographic. The subject were the intruiging tribes on several Indian islands in the Andaman Sea.
On three different islands there are tribes that compare much with Pygmees of the African continent. These tribes still hold to their ancient ways. They don't have agriculture. The women gather knolls in the forests. The men hunt. Since nowadays the wild pig is being hunted by Indian settlers as well, the men started to extend their hunting grounds to fishing.
A European scientist had done DNA research on the hair she had from individuals that have died some hundred years ago. Her research constitued mostly of X-chromose research. She found that these tribes did indeed come from Africa and moved to the island in the plaeolithic ages (with dugout boats)
However, and Indian scientist met her and compared his results. He had done studies on the Y-chromosomes and came to the startling revelation that the genes of these tribes contained typical Asian features that were older than the African genes. Meaning that there was a migration from Asia to Africa first.
Does anybody know more about this? |

Sweetsunray mentioned this thread in the Tsunami discussion - bringing it back to your attention.
Here's an article, free online, from Am J Hum Genet. 2003 Jan;72(1):178-84. Epub 2002 Dec 11. about The Genetic Origins of the Andaman Islanders
(found with Google Scholar, btw... love that tool)

One of the problems with trying to decide where "we" come from is that we are comprised of genes that evolved in many different places. Not all human gene flow was *out* of Africa, and within Africa not from just one place.
I thought I was wrong once, but it turned out I was mistaken about that. |

Thanks Thalion. Great article.
Another resource on general migration is "Genes, Peoples, and Languages" by Luigi Luca Cavalli-Sforza. It is a fascinating read and the culmination off Cavalli-Sforza's work. (I think I saw this on your book shelf cavebear!)
Here is a review of Genes, Peoples, and Languages.

Close, but not quite. I have Cavalli-Sforza's 'The Great Human Diasporas' and 'The History and Geography of Human Genes'. I will have to look at 'Genes, People, and Languages', though. And the new Jared Diamond book, too.

National Geographic's Genographic project says its Africa.

On a different topic could anyone suggest some good books/websites on anthropology for novices like me.

Hitman84, Cavebear, Scott, and all:
The majority of what evidence there is, both molecular and archaeological, seems to indicate that the "modern morph" originated in Africa and spread from there. The "modern morph" is pretty much, IMO, the "glue" that holds the human race together. Which doesn't mean certain regional variations didn't get passed down by more "archaic" humans from elsewhere.
