Abstract

Measures of similarities and differences among organisms are basic to many branches of biology. Systematics is the codification of such information. Lewontin (4) has stated recently that “the major unsolved problem of descriptive population genetics is an adequate specification of the genetic difference between two closely related species as compared to the genetic difference between populations of the same species.” A reasonable solution to this problem cannot be expected until it becomes possible to state the problem more precisely. For example, one cannot expect “an adequate specification of the genetic difference between two closely related species...” unless there is an adequate specification of specific and intraspecific categories. Then again, biologists have never agreed on what they have meant by genetic differences, genetic relatedness, etc. Usually some measure of total difference is implied though, of necessity, only a minute and unknown fraction of the total difference is actually dealt with.
