A team of geneticists believe they have shed light on many aspects of how modern humans emigrated from Africa by analyzing the DNA of the Orang Asli, the original inhabitants of Malaysia. Because the Orang Asli appear to be directly descended from the first emigrants from Africa, they have provided valuable new clues about that momentous event in early human history.
  The geneticists conclude that there was only one migration of modern humans out of Africa - that it took a southern route to India, Southeast Asia and Australasia, and consisted of a single band of hunter-gatherers, probably just a few hundred people strong.
