Summary Introduction
Introduction: “Yellow-rumped Warblers” are fairly large birds with a large head, strong bill, and long-narrow tail. Color pattern of these birds differ during summer and winter. Both sexes exhibit attractive gray color during summer with white flare in wings, yellow color on the face, sides, and rump. Males exhibit remarkable shaded pattern, while females are dull and may show some brown color. During winter, these birds are pale brown in color and exhibit a bright yellow rump with some yellow on the sides.

Distinct species that are able to interbreed in nature are said to “hybridize,” and their offspring are called “hybrids.” The gray oak and the Gambel oak can mate to produce fertile hybrids in regions where they co-occur. However, the gene flow in nature is sufficiently limited that, overall, the two species remain phenotypically distinct. If the hybrid offspring survive well and reproduce to the extent that there is a large population of hybrid individuals that breed between themselves but do not interbreed with either of the two original parent species (the gray and the Gambel), which of the following would you say most likely led to the new hybrid species?(a) prezygotic reproductive barriers (b) sympatric speciation (c) allopatric speciation (d) postzygotic reproductive barriers (e) none of the above
If all the blue dots represent FST values between one species in the Americas and one species in Oceania, does this pattern of genetic similarity on the graph suggest that Native Americans and the people of Oceania followed very different migration routes? Why or why not?
If a geographic barrier is removed and the two reunited populations intermingle and breed, what attributes must the offspring have in order for the two populations, according to the biological species concept, to be considered still the same species?

- a.) In either a secondary or a primary hybrid zone, what do the graphs above indicate about the relative fitness of the hybrid toads away from the 0-kilometer site on the cline? Why? b.) One explanation for the “stepped cline” in both gene frequencies and morphology is that B. bombina and B. variegata first diverged in allopatry and are now forming a secondary hybrid zone. Is the spatial pattern of genetic and morphological variation consistent with this explanation? Why or why not? c.) What would have to be true for the ecological niches of these two-color forms of toad for disruptive selection to be acting on so many loci in parapatry?arrow_forwardIn the United States, the rare red wolf (Canis lupus) has been known to hybridize with coyotes (Canis latrans), which are much more numerous. Although red wolves and coyotes differ in terms of morphology, DNA, and behavior, genetic evidence suggests that living red wolf individuals are actually hybrids. Red wolves are designated as an endangered species and hence receive legal protection under the Endangered Species Act. Some people think that their endangered status should be withdrawn because the remaining red wolves are hybrids, not members of a "pure" species. Do you agree? Why or why not?arrow_forwardDo you believe that because insect beak length has changed in opposite directions in the Florida and the Texas populations that we have stronger evidence that natural selection was acting directly on beak length in these populations? Or is it equally likely that natural selection is only acting on a trait correlated with beak length in the Florida and Texas populations?arrow_forward
- The red wolf (Canis rufus) was once widespread in the southeastern United States but was declared to be extinct in the wild. Biologists bred captive red wolf individuals and reintroduced them into areas of eastern North Carolina, where they are federally protected as endangered species. The current wild population is estimated to be about 100 individuals. However, a new threat to red wolves has arisen: hybridization with coyotes (Canis latrans), which have become more numerous in the areas inhabited by red wolves. Although red wolves and coyotes differ in morphology and DNA, they are capable of interbreeding and producing fertile offspring. Social behavior is the main reproductive barrier between the species and is more easily overcome when same-species mates are rare. For this reason, some people think that the endangered status of the red wolf should be withdrawn and resources should not be spent to protect what is not a “pure” species. Do you agree? Why or why not?arrow_forwardWhich species from Figure 1 has the most amino acids that are different from those of humans? Which species has the most amino acids in common with humans?

Which organisms in Figure 1 share the most distant common ancestors?arrow_forwardIf you had measured a set of morphological traits (beak depth, wing length, leg length, tail length, body size) in both the parent and offspring generations, would it be useful to measure any changes in these traits in the parent generation after the drought killed the birds with shallower beaks? Could any such changes measure a correlated response to natural selection on beak depth? Why or why not?arrow_forward
- How are Belyaev and Trut’s breeding practices similar to, and how do they differ from,the way natural selection normally occurs?arrow_forwardSpecies A and B have long wings, whereas species C has short wings. Which of the following pieces of evidence would best support the hypothesis that long wings are a synapomorphy? A. DNA evidence showing that species B and C are sister species B. Fossil evidence showing that the common ancestor of species A, B, and C had short wings C. DNA evidence showing that species A and C are sister species D. Fossil evidence showing that the common ancestor of species A, B, and C had long wings E. Evidence showing that species A and B live in an environment that favors long wings, whereas species C lives in an environment that favors short wingsarrow_forwardWhen we take, say, 100 individuals of a species of beetle from the wild and place them in a new environment that is not so different that they are unable to thrive but different enough so that they are experiencing a new selective regime, say, a lower temperature, what typically happens? A - Sexual selection causes some larvae to be able to survive in the cooler temperatures and other individuals to be unable to survive because they need warmer temperatures. B - We are unable to measure phenotypic selection, presumably because we do not have much variation among individuals for how they handle temperature. C - The founder event assures us that the new population will be strictly representative of the source population (especially if we took all the 100 from the same location rather that from throughout the range of the species). D - The population evolves to be tolerant of the lower temperature; it can do this because of latent variation already in the 100 founding individuals. E -…arrow_forward
