Quizplus · Accepted Answer

A paraphyletic group includes some but not all descendants of a common ancestor, which means it does not include all the descendants and is not a complete lineage. Monophyletic groups include all descendants of a common ancestor, while polyphyletic groups do not include the most recent common ancestor of its members. Polytomy refers to a situation where there are multiple branches arising from a single node, indicating that the relationships between these branches have not been resolved.
