What do all vertebrates and invertebrates have in common? They are prokaryotic. They are covered by an outer skeleton. They are multicellular. They are bilaterally symmetrical.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
