Review Quiz What is an incorrect statement about vestigial organs? a. The human appendix and the snake’s pelvis are examples of vestigial organs b. Vestigial organs are structures that were once useful to the species’ ancestor but no longer serve a useful function c. Vestigial structures show common relationships with ancestral species d. Vestigial organs are adaptations that allow organisms to survive in their environment What is an incorrect statement about vestigial organs? a. The human appendix and the snake’s pelvis are examples of vestigial organs b. Vestigial organs are structures that were once useful to the species’ ancestor but no longer serve a useful function c. Vestigial structures show common relationships with ancestral species d. Vestigial organs are adaptations that allow organisms to survive in their environment What statement is correct about embryology? 8 a. Scientists can use embryos to shows if species were in existence before dinosaurs b. Similarities in embryos of different species suggest a common ancestor c. Embryology is the study of reproductive methods in organisms d. Only one vertebrate species has tails and gill slits at some point in its early development What statement is correct about embryology? a. Scientists can use embryos to shows if species were in existence before dinosaurs b. Similarities in embryos of different species suggest a common ancestor c. Embryology is the study of reproductive methods in organisms d. Only one vertebrate species has tails and gill slits at some point in its early development Which statement best describes 11 Charles Darwin’s theory of evolution by natural selection? a. Species change whenever individuals in the population adapt to their environment b. Most species in nature change when humans select which individuals to breed c. Species that have favorable traits live longer and pass those traits on to offspring d. Animal populations change in appearance mostly due to favorable mutations in DNA Which statement best describes 11 Charles Darwin’s theory of evolution by natural selection? a. Species change whenever individuals in the population adapt to their environment b. Most species in nature change when humans select which individuals to breed c. Species that have favorable traits live longer and pass those traits on to offspring d. Animal populations change in appearance mostly due to favorable mutations in DNA Which is not true about fossil evidence? a. Nitrogen-dating gives the absolute age of a fossil b. Fossils found in geologic columns of sedimentary rock give a relative age c. Fossils can be imprints, molds, bones, or whole organisms d. Fossils allow scientists to determine relatedness by comparing structures and anatomy of different organisms Which is not true about fossil evidence? a. Nitrogen-dating gives the absolute age of a fossil b. Fossils found in geologic columns of sedimentary rock give a relative age c. Fossils can be imprints, molds, bones, or whole organisms d. Fossils allow scientists to determine relatedness by comparing structures and anatomy of different organisms Which statement is not correct 24 about divergent evolution? a. It results in homologous structures b. It can result in adaptive radiation c. It leads to speciation – one species becoming many due to new adaptations in different environments d. It can be illustrated as: Which statement is not correct 24 about divergent evolution? a. It results in homologous structures b. It can result in adaptive radiation c. It leads to speciation – one species becoming many due to new adaptations in different environments d. It can be illustrated as: Convergent evolution leads to: 23 a. Homologous structures with common origins that are modified for different environments b. Analogous structures with common origins that are modified for different environments c. Homologous structures that have different origins but similar functions d. Analogous structures that have different origins but similar functions Convergent evolution leads to: 23 a. Homologous structures with common origins that are modified for different environments b. Analogous structures with common origins that are modified for different environments c. Homologous structures that have different origins but similar functions d. Analogous structures that have different origins but similar functions Which of the statements does not 25 accurately describe natural selection: f. Organisms that are best adapted for their environment live longer and produce more offspring g. Humans select organisms with desirable traits to interbreed and pass those traits to the next generation h. Organisms which have certain traits that help them survive are more likely to pass those traits onto their offspring j. It is when nature selects traits that will most help an organism survive and reproduce in its environment Which of the statements does not 25 accurately describe natural selection: f.
