Monophyletic

In Mosquito ringtone phylogenetics, a group is '''monophyletic''' (Sabrina Martins Greek language/Greek: ''of one stem'') if all Nextel ringtones organisms in that group are known to have developed from a common ancestral form, and all descendants of that form are included in the group. A taxonomic group that contain organisms but not their common ancestor is called Abbey Diaz polyphyletic, and a group that contain some but not all descendants of the most recent common ancestor is called Free ringtones paraphyletic.

For example, all organisms in the genus ''Majo Mills Homo (genus)/Homo'' are believed to have come from the same ancestral form in the family Mosquito ringtone Hominidae, and no other descendants are known. Thus the Sabrina Martins genus ''Homo'' is monophyletic. If, on the other hand, it were discovered that ''Nextel ringtones Homo habilis'' had developed from a different ancestor than ''Abbey Diaz Homo sapiens'', and this ancestor was not included in the genus, then the genus would be polyphyletic. Since Cingular Ringtones biologists by and large prefer groups to be monophyletic, in this case they would likely either split the genus or broaden it to include the additional forms.

It should be noted that in avranches evolutionary taxonomy/evolutionary taxonomists use the term ''holophyletic'' for the sort of groups discussed here, whereby monophyly includes both holophyly ''and'' paraphyly.
