Students have asked these similar questions
A taxonomic group that contains species that have similar phenotypes due to convergent evolution is
a. paraphyletic.
b. monophyletic.
c. polyphyletic.
d. a good cladistic group.
Two different monophyletic groups that share common ancestry with each other more recently than either does with other taxa are known as?
Monophyletic groups are desirable in classification as they
Select one:
a.reflect evolutionary relationships
b. minimise name changes from old to new classifications
c. result in fewer groups and are therefore more parsimonious
