A populaon of caterpillars feeds on the leaves of trees in a forest and is, in turn, food for birds that eat them oﬀ of the tree leaves. Given this informaon, which adaptaon would be most likely to evolve? a. Caterpillars would evolve to a larger size. b. Caterpillars would evolve to eat the bark, as well as the leaves. c. Birds would evolve to eat more types of insects. d. Caterpillars would evolve to a color that matched the leaves they eat. e. The caterpillars' cocoons would evolve to be more resistant to damp weather. 1 points QUESTION 2 A primary source for new, unique genes in a populaon is: a. Mutaon b. Natural selecon c. Arﬁcial selecon d. Crossing over e. Virus infecon 1 points QUESTION 3 Aﬅer a rapid change in climate, one species of bird quickly adapts to the change, but others in the area do not. What is the most likely conclusion about the quickly adapng species? a. They had a greater need to evolve than the other species. b. They already had some alleles in their genome that were adapve in the new environment. c. They reproduced more slowly than the non-adapng species. d. They pass more of their DNA to their oﬀspring than the slowly adapng species. e. They have a higher rate of mutaon than the other species. 1 points QUESTION 4 Drug resistance to an-HIV drugs is a serious problem. Which of the following facts about HIV is the most direct reason why drug resistance appears so rapidly? a. It has a high rate of mutaon. b. It is replicated in T cells. c. It is a virus. d. It is found in the blood. e. It is sexually transmied. 1 points QUESTION 5 Evoluon is: a. A rare event b. Currently occurring only in scienﬁc laboratories c. Constantly occurring at the same rate in all organisms d. A process that occurs as a result of diﬀerences in reproducve ﬁtness e. A process that occurred only in the past 1 points QUESTION 6 How can we explain the observaon that traits, such as skin color, are fairly consistent within a racial group, but alleles for skin color aren’t consistent? a. There's no relaonship between alleles and skin color. b. Skin color is inﬂuenced by many genes, so several diﬀerent gene pools can produce the same skin color. c. Only one gene is important in skin color, and, when analysis is limited to that gene, there’s clear evidence of a long separaon of groups. d. Few allele variaons between groups are just what you would expect if races were genealogical species. 1 points QUESTION 7 Many lines of evidence suggest that human populaons aren’t disnct races. What keeps us so similar, even though adaptaons to local condions have occurred? a. Members of diﬀerent populaons mate with each other. b. Natural selecon has acted in the same way for all groups of humans. c. Populaons mate assortavely. d.

When a breeding population is blown onto an island with a choice of either very small nuts or very large nuts, members of the group began to specialize, one group eating only very small or very large nuts, depending upon their beaks.

Alleles Question 5 During the 19th century, sea otter s were hunted almost to the point of extinction. When the number of sea otter s became ver y low, the ecosystem of kelp bed “forests” also declined. Scientist s discovered that the sea otter s were predator s of sea urchins, which were, in turn, predator s of the kelp. When sea otter s declined, the sea urchin population s grew, destroying the kelp ecosystem and the man y specie s that depended on it. It wa s then understood that sea otter s were ________ in this ecosystem. Correct Answer: d. a keystone species Question 6 A particular Galápago s finch use s the sharp point of it s bea k to brea k open small nut s and the strength of it s jaw s to crack open larger nuts.
