WebIn biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all … Webmolecular similarities would be recognized as reflecting homology at a deeper level (forelimbs). In other studies, the danger arises when evidence beating on homology is less extensive or decisive (or less well known to the average molecular or developmental biologist) than in this example.
