Homology (biology) - Wikipedia
In biology, homology is the existence of 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, the arms of primates, the front flippers of whales and the forelegs of dogs and horses are all derived from the same ancestral tetrapod structure.

Chordates comprise lampreys, hagfishes, jawed fishes, and tetrapods, plus a variety of more unfamiliar and crucially important non-vertebrate animal lineages, such as lancelets and sea squirts.

Peristome - Wikipedia
Peristome (from the Greek peri, meaning 'around' or 'about', and stoma, 'mouth') is an anatomical feature that surrounds an opening to an organ or structure.Some plants, fungi, and shelled gastropods have peristomes.
Does homology provide evidence of evolutionary naturalism ...
Homology involves the theory that macroevolutionary relationships can be proven by the similarity in the anatomy and physiology of different animals. Since Darwin, homology has been cited in textbooks as a major proof for evolution. A review of the literature on homology indicates that the theory ...
