In , and a group that contains some but not all descendants of the most recent common ancestor is called Paraphyletic . For example, all organisms in the genus '' Homo '' are inferred to have come from the same ancestral form in the family Hominidae , and no other descendants are known. Thus the Genus ''Homo'' is monophyletic. If, on the other hand, it were discovered that '' Homo Habilis '' had developed from a different ancestor than '' Homo Sapiens '', and this ancestor were not included in the genus, then the genus would be polyphyletic. Since Biologist s by and large tend to accept groups when they are monophyletic, in this case, they would likely either split the genus or broaden it to include the additional forms. Splitting the genus may split explanations of functional evolution to require convergence. Some Evolutionary Taxonomists prefer to use the term holophyletic to describe this sort of group and instead use monophyletic in its older sense, where it refers to both holophyletic and Paraphyletic groups. Sometimes taxonomists are frustrated fitting plant species into a monophyletic group because of in eastern Washington . Unity of explanation through functional evolution is challenged by the atomizations required by strict monophyly. SEE ALSO REFERENCES |
