Unformatted text preview: properly based on convergent features in addition to shared derived characteristics. C. The ancestral group is often identified by out- group analysis. D. All of the above answers (A- C) are correct. E. None of the above answers is correct. 9. Which of the following statements best describes the rationale for applying the principle of parsimony in constructing phylogenetic trees? A. B. C. D. E. Once a trait changes, it never reverses its condition. Traits that are similar are more likely to be due to convergent evolution than common ancestry. Similarity due to common ancestry should be more common than similarity due to convergent evolution. All species have an equal probability of evolving. Parsimony allows identification of traits that are not genetically determined. 10. Which of these would, if it acted upon a gene, prevent that gene from acting as a reliable molecular clock. A. B. C. D. E. Neutral mutations Genetic drift Mutations within introns Natural selection All of the above (A- D). 3 BIOL 1001M Midterm II KEY Kelly W2013 Gorilla Human Bonobo vA Chimpanzee 11.
