Homology hypothesis
Did you know?
The word homology, coined in about 1656, is derived from the Greek ὁμόλογος homologos from ὁμός homos "same" and λόγος logos "relation". Similar biological structures or sequences in different taxa are homologous if they are derived from a common ancestor. Homology thus implies divergent evolution. For example, many insects (such as dragonflies) possess two pairs of flying wings Web23 feb. 2024 · Homology requires common origin at all levels: genealogy at the population level and orthology at the organism level.
