Review proteins in Chapter Page 4 Which best describes the assumption maximum parsimony is built on? Question options: All of life evolves as a goal driven process under the direction of a higher power. Evolutionary events occurred in the simplest, most obvious way. Shared derived characteristics define monophyletic groups. Molecular data is superior to morphological data when reconstructing evolutionary events. Hide Feedback Great job. What is a diagram used to represent evolutionary relationships between taxa called? Question options: phylogeny clade branch systematic Hide Feedback Great job. Which assumption of cladistics is correctly stated? Question options: There are multiple universal last common ancestors (LUCA). The polarity of a character state change can be determined.

How has molecular systematics changed the how organisms had been classified? Question options: Sometimes errors are uncovered and taxa are reclassified from molecular systematics. Morphologic homology has allowed for the calibration of a molecular clock. Classification has reverted to the Linnean system based on molecular systematics. Molecular systematics has confirmed earlier classifications. Hide Feedback Great job. What term describes the forelimb bones of a bird, bat, horse, whale and human?
