Psychologist David Premack, emeritus professor of psychology at the University of Pennsylvania is famous for having taught language to chimpanzees. Premack has shown that the chimpanzees can understand the language but cannot produce it. The epigraph at the head of the webpage for the ‘Third Conference on Evolution of Languages’ carried this provocative statement by Premack:
“HUMAN LANGUAGE IS AN EMBARRASSMENT FOR THE EVOLUTIONARY THEORY”
The above statement neatly sums up the mood of the linguists. But look at the map of human migration generated by the molecular biologist and compare it with the presence of various language families in the world.

Indo-European family,Iranian, an and Arabic, an Afro-Asian language, or between Dravidian Tamil and Indo-European Oriya. We have to find a satisfactory explanation for the abrupt discontinuities of the Afro-Asiatic and Dravid language families with the Indo-European language family. There is no historical evidence for the alleged Aryan conquest of a Dravidian India that replaced speakers of Dravidian languages in the North India with the Indo-Europeans. In the last few years, researches in molecular genetics have completely and convincingly demolished the Aryan Invasion Theory (AIT) proposed by the German linguist Max Muller in the 19th century. A complete understanding of the factors affecting the linguistic history of the world continues to elude as well as excite the investigators and the public alike. Christiansen, M. H. and S. Kirby, editors of the book ‘Language Evolution’ (2003) have termed the subject as “the hardest problem in science”.
