- . 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.arrow_forwardEyes are often used in arguments for intelligent design because many consider this organ to be too complex to have evolved by chance alone. However, complex lensed eyes evolved independently both within cephalod mollusks and vertebrates including our own ancestor. In the evolution of these structures the corresponding phylogenies revealed that both: A) were preceded by the evolution of 'simple' light sensing eyes, thus having adaptive intermediate evolutionary steps. B) lacked intermediate evolutionary steps involving the evolution of 'simple' eyes. C) had intermediate evolutionary steps, but ultimately the vertebrate eye had a superior 'design' without any kind of blind spot, relative to the simple invertebrate cephalopod eye. D) were preceded by vestigial non-functional optic structures.arrow_forwardWhich of the following best describes the evolution of smell in chordates? A) Ancestrally, jawless fish had few ancestral scent genes that coded for receptors resembling a combination of water and air receptors. Subsequently these genes were duplicated and specialized through natural selection either for use in water or air. B) Ancestrally, all olfactory receptors where specialized for water as the ancestor of all vertebrates was aquatic. Only once did olfactory genes become duplicated and specialized and this was in the transition to land for receptors that work in air. C) All chordates share the same number of scent receptor genes. However, they have become variously deactivated through natural selection due to either unuse or a tradeoff for sight genes. D) None of the above.arrow_forward

- Most animals show derived characteristics (character states) that differentiate them from their common ancestor (ancestral character state). However, evolution can also move in reverse, involving the change of a derived character state back to an ancestral state. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class. Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state. Make sure to use examples provided in this class.arrow_forwardThe path of whale evolution has involved the reduction or loss of several traits that are still prominent in most other mammals. TRUE (1) or FALSE (2). In terrestrial mammals, the sense of smell (olfaction) involves receptor proteins encoded by a number of genes. Whales don't have a sense of smell underwater, but their genomes still contain copies (pseudogenes) of some of these olfactory genes in their genomes. Because they are still present in whales' genomes, these genes must serve some other function in whales. Whales have some vestigial features like muscles that are attached to external ears in other mammals, even though whales have lost their external ears. Humans also lost some traits (e.g., body fur) and also have some vestigial traits, such as a mechanism to cause fur to stand on end even though we are mostly hairless (i.e., arrector pili muscles that produce goosebumps). Some features like hindlimb buds and whiskers are observed…arrow_forward(a) How do you describe the data from the amino acid sequence to anatomical features provided in the cladogram?
