- Exaptations are traits that: a. prepare some organisms for future environmental changes. b. appear in lineages as a result of an adaptive radiation. c. evolve in anticipation of a species future needs. d. are useful in new situations before natural selection alters them for a new function. e. occur in animals, but not in plants.Match the descriptions/examples types of evidence that support evolution. 1.Biogeography 2.Comparative Embryology 3.Comparative Anatomy 4.Molecular Biology A.Organisms in New Zealand are more similar to organisms in Australia than they are to organisms in North America . B.The embryos of many species have gill pouches even though the gill pouches are not used in these species . C.The forelimbs of the human ,cat ,whale and bat have many similar bones despite the fact that the forelimbs have different functions . D.The Human genome is 98% identical to the Chimpanzee genome .1. Embryology does NOT suggest which of the following? A. Developmental mechanisms are unique for every different type of life and share no commonalities. B. Human embryos pass through embryonic stages inherited from their ancestors. C. Developmental mechanisms are evolutionarily modified in a way that is unique to an organism’s way of life. 2. Which comparative anatomy example does NOT support the theory of evolution? A. Bats, humans, and cats have similarly constructed forelimbs and thus suggest a common ancestor. B. The genus of legless lizards are no longer considered lizards and are now part of the snake genus. C. Vestigial organs are structures that are no longer necessary for survival and are thus gradually becoming nonfunctional and reduced in size. D. All statements support the theory of evolution
- 1.Chimpanzees and humans appear very much alike because of? * a. common adaptations to similar environmental conditions evolved in both b. They shared common traits c. They shared analogous traits d. Genetically shared 50% of their genes. 2. Circle the letter of each sentence that is true about evolutionary relationship of organisms? * a. DNA evidence shows that the giant pandas are more closely related to raccoons than bears. b. Scientist infer that the species with similar body structure and development patterns inherited many of the same genes from acommon ancestor.a c. Scientist never have to change their hypotheses about species relationships. d. Scientist can compare protein structure to determine how closely two species are related .. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.You have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:
