Monophyletic
Monophyletic group is the one which includes an ancestor and all of its descendants.
Polyphyletic group is the one which includes descendants of more than one ancestors.
Paraphyletic group is the one which includes an ancestor but not all of its descendants.
Please rate high.

Of what monophyletic group is "choanae" a shared derived character? 9. What shared derived character is indicated for Tetrapoda? 10. Name any character on the cladogram that is a shared ancestral character for Tetrapoda. 11. According to the principle of maximum parsimony, we should first investigate the...
Monotremata Marsupialia Assume the mammal cladogram on the right depicts accurate evolutionary relationships. While there is no absolute time on this cladogram, there is relative time running from left to right (right is more recent). Answer the following questions about this tree. Afrosoricida - Macroscelidea Tubulidentata Proboscidea Hyracoidea Sirenia Xenarthra Dermoptera 1. Monotremes (Monotremata) are the only mammals (extinct or extant) that do not give live birth. Based on this information and this tree, what type of group are mammals...
For the four evolutionary processes below, indicate: how they affect allele and genotype frequencies within a population, whether or not these effects are random, and how they affect differentiation between populations.
