Indigenous Arabs Direct Descendents of Modern Human Wave From Africa?

PhysOrg is running a story about research coming out of Weill Cornell Medicine and Qatar.  Abigail Fagan writes:
The investigation, published online Jan. 4 in Genome Research, sequenced the genomes of 104 Arabian Peninsula natives and compared them with 1,092 genomes from worldwide populations. The researchers compared each pair of genomes in the sample, which allowed them to cluster research participants by genome similarity so that an evolutionary tree emerged. The genomes of indigenous Arabs resulted in a unique cluster separate from the initial African population, illustrating the formation of a distinct population. European and Asian clusters diverged after the Arab population.
These data reinforce the "southern route" model of early modern human origins, which argues that early modern humans left Africa initially by crossing over or ferrying over the northern tip of the Gulf of Aden, near what is currently Djibouti.

  1. So this is part of the wave that spread through India and on to Australia?

  2. Looks that way. There was a hiccup along the way in the form of the Toba eruption of 71 kya, which seems to have stopped the wave of migrations in their tracks for a while but it looks like people got to China and Australasia first.
