- Polyphyly abstract "A polyphyletic (Greek for "of many races") group is one characterized by one or more homoplasies: character states which have converged or reverted so as to appear to be the same but which have not been inherited from common ancestors.For example, the group consisting of warm-blooded animals is polyphyletic because it contains both mammals and birds, but the most recent common ancestor of mammals and birds was cold-blooded[citation needed]. Warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds[citation needed]. Other examples of polyphyletic groups are protozoans and algae.Many biologists aim to avoid homoplasies in grouping species together and therefore it is frequently a goal to eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes.Researchers concerned more with ecology than with systematics may take polyphyletic groups as legitimate subject matter; the similarities in activity within the fungus group Alternaria, for example, can lead researchers to regard the group as a valid genus while acknowledging its polyphyly.".
