Which statement correctly explains the relationship between taxonomic categories and phylogenetic classification?
Taxonomic categories are arbitrary and have no relationship to phylogeny.
Taxonomic categories always perfectly match the branching patterns of phylogenetic trees.
Taxonomic categories ideally reflect evolutionary relationships revealed through phylogenetic analysis.
Phylogenetic analysis is used to create taxonomic categories, but they don't necessarily reflect evolutionary relationships.

Polyphyletic groups are problematic in taxonomy because they:
Include all descendants of a common ancestor.
Include the most recent common ancestor and all its descendants.
Do not include the most recent common ancestor of all members.
Represent a single evolutionary lineage.
