A series of six programmes

with Professor Robin Fox and Professor Lionel Tiger

Man has been civilised for only a ten-thousandth of the time it has taken him to develop from the apes. For the rest of that time his body and brain have been shaped by the forces that act upon primates in the wild, and groups of tool-using hunters. This leads Robin Fox and Lionel Tiger to conclude that modern man's behaviour in all its apparent sophistication - including the roles we play as men or women - is actually governed by instincts acquired during the prehistoric struggle for survival.

Many sociologists, anthropologists and zoologists disagree with this point of view and some of them will be taking part in tonight's discussion from the Royal Institution.

Introduced by Professor Sir George Porter
