ABSTRACT

This chapter deals primarily with what is meant by the terms “homology” and “analogy”. The term “homology” itself is widely understood to mean “evolutionary homology,” and such correspondences as those between serial homologs are considered less important. The new comparative anatomy developed techniques of historical reconstruction that had no precedent in the old. “Serial homology is the relation between the iterative homologues of parts which are repeated in linear sequence.” “Antimeric homology is the relation between the iterative homologues of parts that are repeated on the opposite sides of the body.” “Sexual homology is the relation between the iterative homologues of reproductive parts of organisms in species in which a single kind of reproductive apparatus is repeated with variations in individuals having different reproductive roles.” If an anatomist or other comparative biologist can say all he wants, and say it well, with minimal effort, it does not pay to burden his memory with an inflated lexicon.
