A Li'l History Lesson

Between 135,000 and 75,000 years ago, the East-African droughts shrunk the water volume of  Lake Malawi by at least 95%, causing migration out of Africa. Which route did they take? Researchers say their study of the tribes of Andaman and Nicobar islands using complete mitochondrial DNA sequences and its comparison those of world populations has led to the theory of a "southern coastal route'' of migration from East Africa through India. This finding is against the prevailing view of a northern route of migration via Middle East, Europe, south-east Asia, Australia and then to India.
