Textbook Question
Chapter 56, Problem 4S
Refer to figure 56.7. Examine the pattern of beak size distributions of two species of finches on the Galápagos Islands. One hypothesis that can be drawn from this pattern is that character displacement has taken place. Are there other hypotheses? If so, how would you test them?

How do mechanisms of speciation, such as genetic isolation, reproductive barriers, and ecological factors, apply to the human-chimp-gorilla trichotomy?
Discuss the role of these mechanisms in driving speciation and shaping the evolutionary relationships among humans, chimps, and gorillas, based on genetic evidence such as comparative genomics and molecular phylogenetics.
Consider this example. Shorebirds on the Eastern coast of North America feed on the mollusks and tiny crabs along the shore. Birds with tougher beaks are better adapted to crack open the shells of the mollusks, and birds with sharper beaks are better adapted to pierce the shells of crabs. Over time, the shorebirds become two separate species that no longer breed with one another. What type of speciation has occurred?
A.
Sympatric speciation
B.
Adaptive speciation
C.
Microevolution speciation
D.
Allopatric speciation

- Which of the following statement(s) is/are true? Select the best overall answer. a. Kenward et al. reported that for each paired bird with eggs, there were three floaters in a European population of Common Buzzards b. in Complete Migration, there is predictable, seasonal movement of individuals between a breeding range and a non-breeding range (and back again) with no geographic overlap of these two ranges. The Broad-winged Hawk is an example of a species that exhibits Complete Migration. c. A paper by Bednarz et al. published in 1990, demonstrated with observational tallies of migrating raptor species that populations declined in migratory counts during the DDT era. d. all of the above e. only b and carrow_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(b) There is a positive correlation between branch width of trees and hind limb length of the brown anole lizard: Wide branch diameter = long hind limbs Narrow branch diameter= short hind limbs A group of lizards becomes separated from the main group on Island A due to a catastrophic hurricane that carries this small group out to sea. A few lizards are able to make it to uninhabited, dry land (Island B) and breed over several generations separated from the lizards on Island A. Scientists, monitoring the lizard populations, record the change in hind limb length of these two new populations over time. The results are shown below: Island A Island B Linear (Island A) Linear (Island B) 1975 1980 1985 1990 1995 2000 2005 2010 2015 Figure 1: Change in hind limb length of brown anole lizards Page 2 CONT'D from Page 1 i.

- Suppose you have four species of lizard and you are interested in how leg length will change in a single generation of evolution under directional selection. Given the following parameters, which lizard do you predict will change the most in one generation? Species A: Heritability: 0.5, selection differential: 1.2 Species B: Heritability: 0.4, selection differential: -1.9 Species C: Heritability: 0.9, selection differential: -0.67 Species D: Heritability: 0.1, selection differential 3.2 Species A Species B Species C Species Darrow_forwardPlease solvearrow_forwardDarwin’s finches have different beaks in terms of size and shape to be able to eat different food sources like insects, nectar, and seeds. Cactus finches have longer, more pointed beaks to probe cactus flowers compared to their relatives, the ground finches. If a plant disease killed a large portion of the cacti on the Galapagos islands, what would the future populations of finches look like in terms of beak size and shape? Use your knowledge of natural selection to determine which option is most likely. Ground finches would survive and pass on their shorter and wider beaks, so there would be a higher proportion of finches in future generations that have short and wide beaks. Ground finches would survive and pass on their beaks, but they would mate with the remaining cactus finches, creating a new hybrid that is somewhere between short versus long and narrow versus wide. Cactus finches would compete for food with ground finches and exhibit resource partitioning, so the beaks…arrow_forward
- Use each of the following species concepts to write a claim about whether the dark and light fur mice are, in fact, different species. Your claim should demonstrate your understanding of that particular species concept. Mice with light coat colors are found in populations scattered across the southeastern US. Researchers believe the light coat color emerged in a single population. How would a biologist explain the evolution of the light coat color in populations across the southeastern US? Briefly explain your reasoning.arrow_forwardChoose True for yes and False for no, for each of the statements 1) The distribution of the two species-C populations cannot be explained by two totally independent dispersal events by the common ancestor species of A and B. True or false 2) B must share a more recent common ancestor with C1 than it does with C2.

- Two morphological variants in a population of medium ground finch on the Galapagos Islands have been found to exist. Individuals of each variant respond more strongly to songs produced by the same variant, and prefer to mate with individuals of their own morphological variant. What type of speciation could be in progress, and what measurements could inform the extent of prezygotic reproductive barriers that have developed? A. Sympatric speciation by sexual selection; survival and reproductive success of hybrids of the two morphological variants. B. Allopatric speciation by habitat differentiation; survival and reproductive success of hybrids of the two morphological variants. C. Sympatric speciation by sexual selection; frequencies of mating and numbers of viable offspring of the two morphological variants. D. Allopatric speciation by habitat differentiation; frequencies of mating and numbers of viable offspring of the two morphological variants.arrow_forwardOn many remote islands in the Pacific, there are endemic species of wingless insects that apparently have evolved from winged ancestral species that colonized the island in the distant past. For this example, describe the conditions which must have been met in order for winglessness to have evolved, the means by which winglessness was able to increase in frequency in the population, and the mode of selection that must have taken place within this population. Your answer to this question must define and use terminology appropriate to a discussion of evolution.arrow_forwardLook at picture attached A) What does the phylogeny suggest about the evolutionary process that led to the trait differences by habitat? a. convergent evolution b. adaptive radiation c. phenotypic plasticity B) Choose different functional forms from two of the habitats shown in the collage and describe how one or more differences in form may represent an adaptation to their different environment.
