1. According to the Theory of Special Creation, species: • A) they be immutable; them’s ain’t a changin’ nohow • B) no species never gave rise to no new species • C) They all recent, maybe 6000 years recent • D) all of them there above answers is right 2. Which of the following best describes vestigial structures? • A) Vestigial structures are functionless or rudimentary homologs of characters that are functional in close relatives • B) Vestigial structures don't exist in humans • C) Vestigial structures are perfectly adapted for their particular functions • D) Vestigial structures are similar structurally and functionally to comparable structures in other organisms 3. Homologous characters • A) are similar in function • B) are known only from gross anatomy, not from any other biological feature • C) show underlying structural similarity even when their superficial structure is different • D) are superficially similar • E) result from convergent evolution 4. What constitutes evidence of the fact of evolution • A) observation of species change over time, e.g. anti-biotic resistance in bacteria • B) observation of fossil series with intermediate forms • C) observation of shared ancestral homologous characters • D) observation of vestigial traits, like embryonic tails and adult tail bones in humans • E) all of the above 5) The theory of descent with modification predicts that a region's extant plants and animals will be most similar to fossils __________ • A) from the same region • B) from regions with the same environment • C) from transitional forms 6) This diagram represents two sedimentary rock layers with one intrusion/dike and a set of boulders. According to the principles used by 19th-century geologists to establish the relative ages of the major rock formations of Europe, what is the correct sequence of the illustrated structures (oldest to youngest)? • • • • A) A, C, B, D B) A, C, D, B C) A, B, C, D D) C, D, A, B
