Quiz 14 Ch 14 Name________________________ Remote # ____________ 1. Structures that may differ in function but a. early embryonic development is that have similar anatomy, presumably conservative because of descent from common b. ancestral vertebrates possessed genes ancestors, are called ______. that directed the development of tails and a. analogous structures gill slits, and all of their descendants still b. homologous structures retain those genes c. vestigial structures c. genes that modify the developmental pathways in vertebrates arose later in 2. Structures that serve no apparent evolution purpose but are homologous to functional d. all of the above structures in related organisms are called _______. 5. Which of the following is a basic a. analogous structures requirement for natural selection to be an b. homologous structures effective evolutionary force? c. vestigial structures a. Mutation must occur frequently. b. Individuals reproduce at a rapid rate. 3. Which of the following lines of evidence c. Each population is limited to a small size. support(s) the idea that evolution occurs? d. A population exhibits some genetic a. the fossil record variability. b. genetic and biochemical analyses e. all of the above c. comparative anatomy and embryology d. artificial selection 6. What does the idea of "uniformitarianism" e. all of the above suggest about the geological record and the age of Earth? 4. All vertebrate embryos resemble each a. Earth was only 6000 years old. other during the early stages of b. Species were evidence of acts of divine development. For example, fish, turtles, creation. chickens, mice, and humans develop tails c. Earth's species were created initially but and gill slits during early stages of many were destroyed by successive development. This suggests that _________. catastrophes. 1 d. Natural processes (e.g., sedimentation organism. due to river flow) occurring over long d. Mutations that are favored by selection stretches of time accounted for the thick are more likely to occur. layers of rock where fossils are found, rather than cataclysmic events. 10.

Which of the following would be a. analogous structures considered to be an example of analogous b. homologous structures structures? c. Both the first and fourth answers are a. molar teeth in a vampire bat correct. b. superficially similar structures in d. evidence of convergent evolution unrelated species e. evidence of divergent evolution c. internally similar structures (e.g., of birds and mammals) that are used for many 11. Natural selection acts on ____________, different functions while evolution occurs in ________________. d. Both the first and third answers are a. individual organisms; populations correct. b. separate organisms; populations c. single cell organisms; species 8. Charles Darwin was NOT influenced by d. individual organisms; families which of the following people in formulating his ideas about natural selection? a. Thomas Malthus b. Charles Lyell c. William Smith d. Gregor Mendel 9. Which of the following is an incorrect statement about mutation? a. Mutation introduces variation into a population. b. Mutations can be inherited from parents to offspring. c. Mutations may have no effect on the 2
