OSMT Exam Questions with verified Solutions 100% Solved 2024 Why doesn't phylogenetic systematics have a fixed number of hierarchical categories like Linnaean systematics? - answerEach branching point is a hierarchical level in the nested structure of phylogenetic systematics. The number of branching points—and therefore the number of possible hierarchical levels—varies substantially from one lineage to another. What aspect of evolution does phylogenetic systematics represent more c...
