Explanation:

Plesiomorphy describes an ancestral state for a particular feature/character which is shared among several taxa of a tree and probably these taxa are closer to the base of the tree. Monophyletic refers to a group consisting of an ancestor and all of its descendants. Homoplasy is the independent evolution of similar features in species of different lineages. Polyphyletic groups are composed of unrelated organisms that lack a common ancestor.
