Question

1) Explain the differences and similarities between Evolutionary Systematics, Phenetics, and Cladistics. 2) It has been argued by some systematists that we should abandon Linnaean taxonomic ranks above the genus level. Provide at least two reasons why they might argue this. Do you agree or disagree with this argument? Explain your reasoning. 3) What is the purpose of an outgroup taxon in a cladistic analysis? How should one select an appropriate outgroup taxon for their study sample? Feel free to use example clades in your answer. 4) Give examples of monophyletic, paraphyletic, and polyphyletic groups. (or "groups" in most cases). (I do not mean definitions, real-world examples of various organisms)
