Taxa in a study. Ideally we would study every single species within a higher level taxon such as all species of butterflies and moths (Order: Lepidoptera). In that case, our phylogenetic analysis would not be biased. However, scientists cannot feasibly study all members of a taxon, even if we discovered every species. As such researchers carefully choose a subset of known taxa to study. Given what is said above, what type of taxa should a scientist use for a phylogenetic study? A. A conceptual model.
B. A visual diagram showing patterns of ancestry.
C. A branching diagram displaying a pattern of evolutionary relationships.
D. All of the above.
