- The Theory of Evolution contends that species have changed through time and are related to one another through descent from a common ancestor. Which of the following prediction follow from the Theory of Evolution? A. The fossil record should contain intermediate forms between major taxonomic groups B. The oldest rock strata are much more likely to contain complex fossils than simple fossils. C. Fossils are always a representation of species that are currently alive (ie extant) even if they have not been detected yet as living on earth at the present time D. All species are unigue and originated independently from each otherarrow_forwardPhylogenetic trees are constructed based on Group of answer choices a. shared ancestral characters b. vestigial characters c. homoplastic characters d. cartoon characters e. shared derived characters f. shady charactersarrow_forwardBased on cladistic analysis: O a. paraphyletic and monophyletic groups are equally valid. b. a shared derived trait that unites birds is feathers. c. it is generally easier to identify the later as compared to the earlier members of a natural group. d.

Organisms that share similar characteristics are impliedly understood to have common ancestors, thus having an evolutionary relationship. B. Classification is to organize organisms into groups based on their differences and similarities and evolutionary history, so as evolution changes, classification will also change C. Classification based on evolutionary relatedness always infer that all organisms that evolved similarly shares the same history. D. Homologous structures among organisms depicts the same evolutionary history or paths.arrow_forward
