Textbook Question
Chapter 12.7, Problem 2MC
South China tigers have two color patterns (orange/black and blue/gray), which do not affect an individual’s reproductive success. Over many decades, the tiger population has drastically declined, and all blue/gray individuals have disappeared. What evolutionary process eliminated this color pattern?

Scientists have also noticed unusual coloration among certain condor populations. Andean condors are typically black in color. However, a few unique white feathered individuals have occasionally been noted. These white feathered individuals are not well-camouflaged, and are easily spotted by larger predators. Recently, scientists noted that a black feathered condor had mated with a white-feathered condor, and their three chicks all appeared to have gray feathers. Closer examination of these condor chicks revealed that the chicks actually possessed a mixture of black feathers and white feathers, giving them a gray appearance from a distance. Please NAME and EXPLAIN the genetic phenomenon described here.
An island of the Galápagos archipelago is home to a medium ground finch that subsists mainly by eating seeds. A severe drought struck the island. During the drought, plants produced fewer seeds, and the finches soon depleted the stock of small and soft seeds, leaving only large and hard seeds that were difficult to process. In this environment, finches with deeper beaks were more likely to survive and pass their advantageous traits to their offspring by means of the principle called the 'inheritance of acquired characteristics'.
Question 11 options:
A) True
B) False
Nursing bees take care of the queen and newly hatched bees. However, nursing bees themselves do not reproduce. How could natural selection act upon such behavior?
Because this behavior does not directly benefit the nursing bee itself, it is not favored by natural selection.
Because this behavior increases the number of surviving offspring that share genes with the nursing bee, it is favored by natural selection.
Because this behavior selectively decreases the number of offspring harboring non-similar genes with the nursing bee, it is favored by natural selection.
Because this behavior does not increase the number of surviving offspring that are identical in genes with the nursing bee, it is not favored by natural selection.

- There are two color morphs in boomer foxes (not a real species), red and gray. Both tend to have a single litter of 4 pups, and there is little difference in pup mortality or reproductive success between the two morphs. Red morphs tend to have their litter in their second year, and most die before 5 years old. Gray morphs tend to have their litter in their third year and most live to 10 years old. Given this information which of the following statements below is correct? Group of answer choices Gray morphs and red morphs have same relative fitness Given that the gray morphs live twice as long as the red morphs their fitness is greater Since red morphs reproduce first their fitness is greater than gray morphs Since gray morphs delay reproduction their pups are fatterarrow_forwardFlightless birds on island often have relative on the mainland that can fly. The island species presumably evolved from fliers that, in the absences of predators, lost their ability to fly. Many island population of flightless birds are in decline because rats have been introduced to their previously isolated island habits. Despite current selection pressure in favor of flight, no flightless island bird species has regained the ability to fly. Why is this unlikely to happen?arrow_forwardAssume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.arrow_forward
- In birds of paradise that populate tropical rainforest ecosystems, bright colored beaks and feathers are commonly found. These phenotypes continue to persist, even though brightly colored birds are more easily seen by predators. Which of the following would best describe the reason behind the persistence of these phenotypes in birds of paradise?arrow_forwardA preserve contains the last population of the very rare desert pupfish which is only found in one pool. There are two color forms of this pupfish, one is silver and one is black and the color is inherited. The color forms are equally successful in surviving and having offspring over the long term but the frequency of the two forms varies greatly from generation to generation. Which evolutionary force is causing the fluctuation in frequency?arrow_forwardAccording to the theory of evolution, why have these changes occurred in horse populations over the course of many generations?arrow_forward
- A)Research shows that Neandertals coexisted with at least three other species, including Homo sapiens. There are some humans today that have Neandertal and Denisovan genes. Generate a hypothesis about how their genes are also a part of our genes. B) Using this information: In 1993, primatologist Richard Wrangham proposed that "Bonobo hypersexuality appears closely linked to the evolution of female-female alliances. I suggest that these alliances were made possible by relaxed feeding competition."Generate a hypothesis about why Bonobos behave this way..arrow_forwardOne of Darwin’s finches, the medium ground finch (Geospiza fortis), is found on the small island of Daphne Major. These finches are seedeating birds. A major drought occurred on the island in 1977. Following the drought, the average beak size of medium ground finches had increased about 3%–4%. Why might a drought lead to an evolutionary change in beak size? Propose a hypothesis and explain how you could go about testing it.arrow_forwardThis spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why do you suppose: (a) This bird is confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? Explain in detail. (b) This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it? Explain in detail.arrow_forward
- A population of interbreeding birds has been split by a geological event after which the isolated part of the population started to evolve into an incipient species with different mating rituals. Due to a recent environmental change the two populations are now able to potentially mate again in what is called a hybrid zone. Mating does take place every now and then but the hybrid offspring appear less able to survive. As a consequence, mating rituals start to diverge even further. We call this process of continued divergence? O Fusion O Behavioral isolation Reinforcement O Postzygotic isolation O Stabilityarrow_forwardWhen Charles Darwin visited the Galapagos Islands, he observed the marine iguana. He later decided that the marine iguana evolved from the terrestrial iguana found on the mainland of South America. The marine iguana differs from the terrestrial iguana in several ways. The marine iguana has a flat tail, long claws and sharp teeth while the terrestrial iguana has a round tail, short claws and flat teeth. When looking at the differences between the terrestrial and the marine iguana, which of the following is not evidence that evolution has occurred? * O Homologous structures shared between both iguanas O The biogeography of the iguanas O Comparative embryology of the iguanas The state of Hardy-Weinberg equilibrium present in both iguanasarrow_forwardWhen Charles Darwin visited the Galapagos Islands, he observed the marine iguana. He later decided that the marine iguana evolved from the terrestrial iguana found on the mainland of South America. The marine iguana differs from the terrestrial iguana in several ways. The marine iguana has a flat tail, long claws and sharp teeth while the terrestrial iguana has a round tail, short claws and flat teeth. The marine iguana became a separate species after being geographically isolated on the Galapagos Islands for several years.
