The study of phylogeny rests on our observation of characters of organisms, which may include a of the following EXCEPT a. anatomical feature b. developmental processes. C. DNA sequences. d. Linnaean taxonomy. Charles Darwin inferred the pattern of common ancestry without understanding the basis for heredity. However, if Darwin’s theory of descent with modification is correct then from other a. DNA sequence similarity should reflect patterns of common ancestry inferred from other evidence. b. DNA sequences will indicate the correct phylogeny, and other traits, such as morphology and anatomy, will be irrelevant to common ancestry. c. the hereditary basis of a trait will not matter for understanding its evolutionary history. d. common ancestry will be reflected in phylogenies only for traits that are determined by a single gene. Based on the figure, which of the following statements is true? a. Fish are not a monophyletic group. b. Amphibians are not a monophyletic group. C.
