 P-O-L-Y-P-A-H-E-L-E, a polyphoretic group is a set of organisms, or other evolving elements, that have been grouped together but do not share an immediate common ancestor. The term is often applied to groups that share characteristics that appear to be similar but have not been inherited from common ancestors. These characteristics are known as homo-plagies, and the development and phenomenon of homo-plagies is known as convergent evolution. The arrangement of the numbers of a polyphoretic group is called a polyophilia. Alternatively, polyphoretic is simply used to describe the group whose numbers come from multiple ancestral sources, regardless of similarity of characteristics. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds. Other polyphoretic groups are for example algae, seed for photosynthetic plants, and eat dentates. Many biologists aim to avoid homo-plagies in grouping taxa together and therefore it is frequently a goal to eliminate groups that are found to be polyphoretic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systematics may take polyphoretic groups as legitimate subject matter, the similarities in activity within the fungus group alternatoria. For example, can lead researchers to regard the group as a valid genus while acknowledging its polyophilia?
