Homology

Abstract

“Homology is probably the most important concept in comparative biology. It has been treated in different ways, however, and more than one concept of homology is probably defensible” (Minelli 1994: 18); “Homology is one of the terms most widely employed in biology. Together with species, gene and a few others, it is likely to occur in texts devoted to the most diverse biological disciplines, from MORPHOLOGY to systematics to molecular genetics.
