Abstract

The study of the mechanisms of speciation and of evolution in the animal world is a subject of wide biological interest which in recent years has become the object of an increasingly vast literature. Protein, chromosome and anatomical evolution as well as changes in the patterns of gene expression represent some of today’s most extensively studied themes which require strict in­terdisciplinary approaches. In each animal group, therefore, any conclusion regarding “phyletic relationship” can be drawn only on the basis of all the chromosomal and genetic, as well as biochemi­cal and biometrical, evidence (White 1973a).
