WebHomoplasy. Homoplasy — similarity resulting from evolutionary convergence, parallelism or reversal — has endured, as exemplified in the book Homoplasy: The Recurrence of Similarity in Evolution, edited by Sanderson and Hufford [1996], produced under the expert editorial direction of Charles (Chuck) Crumly of Academic Press to parallel (no pun … WebThe term homology, like the term monophyly, is used in various ways in the systematic literature. However, most recent workers accept the term to mean a shared similarity that is due to (explainable by) common descent. Thus, any similarity that is not explained by common ancestry is not homology.
