The debate over “Out of Africa” — the idea that modern humans came from Africa — will probably rage for some time, but enthusiastic acceptance of the theory is waning. A now famouse paper kicked off a round of debate when it was published:

The finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid haplogroups, as well as all non-African haplogroups do not carry either SNPs M91, P97, M31, P82, M23, M114, P262, M32, M59, P289, P291, P102, M13, M171, M118 (haplogroup A and its subclades SNPs) or M60, M181, P90 (haplogroup B), as it was shown recently in “Walk through Y” FTDNA Project (the reference is incorporated therein) on several hundred people from various haplogroups.

These same researchers also tracked European origins across the millennia:

This study provides a support to the theory that haplogroup R1a arose in Central Asia, apparently in South Siberia and/or neighboring regions, around 20,000 ybp. Not later than 12,000 ybp bearers of R1a1 already were in the Hindustan, then went across Anatolia and the rest of Asia Minor apparently between 10,000 and 9000 ybp, and around 9000 – 8000 ybp they arrived to the Balkans and spread over Europe east to the British Isles. On this migration way or before it bearers of R1a1 (or the parent, upstream haplogroups) have developed Proto Indo-European language, and carried it along during their journey to Europe. The earliest signs of the language on passing of bearers of R1a1 through Anatolia were picked by the linguists, and dated by 9400 – 9600 – 10,100 ybp, which fairly coincides with the data of DNA genealogy, described in this work.

My own take is that we can resolve this logically. We know that Asians are part Denisovan, Dravidians are part Australopithecus, and Africans are part something like Ergaster; other groups may be mixed in too. Europeans, other than a touch of Neanderthal, appear to simply be modern humans.

Then we look at Africa, the most genetically diverse place, and realize that a condition like that only arises if there is backflow, not from outflow. This fits with a group of modern humans arising in India or Siberia, venturing around the world and mixing with Denisova, Ergaster, Australopithecus, etc on the various continents.

Does this tell us much of anything? Only that race, like the even more important ethnicity, is an important record of human history that encodes significant differences between human beings. It might make sense not to import the world to the last bastion of modern humans, since we need a genetic control group.
