The fundamental aim of population genetics is to understand the mechanisms by which living matter evolves, and to develop methods by which we can control the natural, spontaneous processes involved. As regards the study of human evolution in particular, we want to find out what caused the divergence of the branch of the evolutionary tree that led to Homo sapiens, to ascertain how the various sub-branches of this main branch may be classified into distinct races, to discover the means by which the present diversity of the human species is preserved, and to learn how we can guide human evolution into favourable directions. The task which we set ourselves in this book was to show how population genetics has contributed to the achievement of these aims. In conclusion, we would like to lay stress on the inadequacy of our present knowledge about the fundamental process which we have been trying to understand.
