Analogous Homologous Vestigial Unit 4 CHAPTER 15 Evolution 61

5 Chapter Test B CONTINUED Completion Write the correct term in the blank to complete each sentence below. 5. Darwin referred to the selective breeding of domesticated animals as. 6. The evolution of an elongated beak by most woodpecker species is called a(n). 7. Comparing the three white-furred offspring of one polar bear mother to the one white-furred offspring of a second polar bear mother is called. 8. Peacocks developing large tails, as a result of large-tailed males being selected more frequently by females, is called. Part C: Interpreting Graphs 1. Study Figure 1. Identify the type of natural selection illustrated by the graph. Hypothesize why this type of selection is occurring in the snail population. 2. Study Figure 2. Hypothesize why this type of selection is occurring in the squirrel population. Part D: Short Answer Write your response to each statement in the space provided. 1. Apply the four basic principles of natural selection to explain why dark-colored peppered moths replaced light-colored moths during England s initial years of industrialization. Figure 1 Figure 2 62 Evolution CHAPTER 15 Unit 4

6 Chapter Test B CONTINUED 2. Infer the evolutionary significance of the presence of a tail in both a chimpanzee embryo and trout embryo. 3. The bull fur seal and the emperor penguin both have streamlined, fishlike bodies and a layer of insulation underneath the skin. Both animals use webbed forelimbs to swim in an aquatic environment. Identify the evolutionary principle that applies to the evolution of these two animals. Explain. Part E: Concept Application 1. Yellow jackets are wasps with yellow and black stripes that produce a painful sting. The evolutionary adaptation of the syrphid fly is to mimic the yellow jacket. Infer the physical appearance of the syrphid fly and the advantage of its adaptation in its environment. 2. A small population of 250 Saint Lucian parrots lives in the small rain forests of the Caribbean island of Saint Lucia. The parrots never leave the island, and parrots from neighboring islands do not come to Saint Lucia. The parrots live in three rain forest areas, but parrots from all the regions freely mate with parrots from other regions. The appearance and characteristics of the parrots have remained the same for generations without variation. Analyze the description of Saint Lucian parrots and identify the conditions and violations of the Hardy-Weinberg principle that apply to the parrot population. Unit 4 CHAPTER 15 Evolution 63

9 Chapter Test C CONTINUED 2. Contrast the three basic types of organism structures. Provide an example for each structure. 3. A population of animals has a dominant allele for dark-colored fur and a recessive allele for light-colored fur. Sixty percent of the animals are homozygous dominant, 25 percent are heterozygous dominant, and 15 percent are homozygous recessive. Calculate the equilibrium frequencies for each segment of the population. Part E: Concept Application 1. Currently, scientists believe polar bears evolved from brown bears between 100,000 and 250,000 years ago because glaciers isolated a population of brown bears. Apply the four basic principles of natural selection to explain how polar bears evolved from this brown bear population. 2. Human eye color varies from nearly black to light blue. Dark eye color evolved to protect the eye from intense tropical sunlight, but present-day humans do not gain a survival advantage from eye color. Discuss the eye color of present-day humans from an evolutionary perspective. 3. The black-capped chickadee and the Carolina chickadee are two North American bird species that appear nearly identical. The black-capped chickadee remains north of an imaginary line that bisects the United States, and the Carolina chickadee stays to the south of the line.
