Textbook Question
Chapter 33, Problem 3CT
Most bats eat insects or fruit. Vampire bats, however, suck blood from birds or mammals. Like some snakes, and unlike any other mammals, vampire bats have thermoreceptors that can detect body heat given off by prey. Is the heat-detecting ability of vampire bats and snakes a homologous trait or an analogous one? Explain your reasoning.

Voles that are born in the Spring have thin coats as adults, while voles that are born in the Fall have thick coats as adults. Most voles live only a few months; voles born in the Spring are alive during the warm summer season, while voles born in the Fall are alive during the cold winter season. The environment experienced by the mother during pregnancy determines coat thickness in the offspring. Now consider a situation in which the environment the vole mothers during pregnancy changes, such that voles born in the Fall now have thin coats. Assume in this case that the Winters are still cold. This scenario provides an example of which of the following hypotheses?
a.Environment mismatch hypothesis
b.Endocrine disruptor hypothesis
c.Thrifty genotype hypothesis
d.Plasticity first hypothesis
How did the presence of an adaptation change the frequency of a specific trait in hummingbirds?
Most humans enjoy candy, cake, and ice cream. As a result of evolutionary history, we have a wide variety of tastes. This is not true of all animals. Cats do not seek sweets. Over the course of their evolutionary history, the cat family tree lost a gene to detect sweet flavors. Most birds also lack this gene, with a few exceptions. Hummingbirds are sugar junkies.
Hummingbirds evolved from an insect-eating ancestor. The genes that detect the savory flavor of insects underwent changes, making hummingbirds more sensitive to sugars. These new sweet-sensing genes give hummingbirds a preference for high-calorie flower nectar. Hummingbirds actually reject certain flowers whose nectar is not sweet enough!
You are a wildlife biologist researching black rhinos. During your time in Africa, you have observed two particular traits that allow some black rhinos to be better adapted to their environment. The first trait is an extra-long prehensile lip that enables the rhino to have more efficient browsing capabilities than rhinos with the usual size prehensile lip. Second, some of the rhinos in the study have extra-large ears that allow them to hear a potential predator earlier than rhinos with normal size ears. If you could breed black rhinos that have both of these good traits (an extra-long prehensile lip (P) and bigger ears (E), it wouldincrease their chance for survival in the wild. You have chosen the following two rhinos to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Parent 1: Heterozygous dominant for prehensile lip trait. Heterozygous for the longer…

- European moles and Sumatran tigers both have eyes. However, European moles live completely in the dark and have very small eyes, while Sumatran tigers have large eyes that can see prey from far away. What most likely explains why both European moles and Sumatran tigers have eyes and why their eyes are different?arrow_forwardPlease just Do E and Farrow_forwardWhy does natural selection have little effect on senescence? Genes that cause senescence have no variants because they became fixed early in evolutionary history. Low-calorie diets, which may not affect offspring, cause individuals to go through senescence. Reproduction generally occurs before senescence genes begin to produce harmful effects on fitness. Senescence is a result of getting older and is not controlled by genes that can be inherited.arrow_forward
- What evidence can be used to what proves that the males in swamps might be more likely to be blue due to their genes and environment conditions? Explain reasoning.arrow_forwardThe FOXP2 gene is associated with speech in humans. It is also found in chimpanzees, gorillas, orangutans, rhesus macaques, and even the mouse, yet none of these mammals speak. Develop a hypothesis that explains why FOXP2 supports speech in humans but not in other mammals.arrow_forwardAnurans Most anurans breed in water and rainfall stimulates breeding in many species. Ponds may attract aggregations of anurans during breeding season and males usually are the first to arrive. In most cases, females are attracted by vocalizations by males (see beginning of our lab manual). 1) This display is called “semaphoring”. Why was this behavioral adaptation necessary for this particular frog species?arrow_forward
- People who object to evolution sometimes assert that complex organs such as eyes are irreducibly complex, and therefore couldn't have arisen through evolution. Which of the following are insights that evolutionary research has provided on how complex organs arise? For each choice select YES or NO.arrow_forwardA male and female gibbon that are similar in size likely demonstrate the lack of sexual dimorphism… A : due to the polygamous social structure in gibbons. B : as the result of unequal access to resources within their environment. C : which is not related to social structure in gibbons. D : due to adaptations related to Allen’s rule.

- Sugar gliders and Northern flying squirrels are mammals that have many morphological similarities despite being genetically different. Both are nocturnal and have large eyes to help them see in the dark. Both live in trees and have flaps of skin connecting their front and back legs, and when their front and back legs are extended, the flaps allow the animals to glide from one tree branch to another. Sugar gliders are native to Australia, and Northern flying squirrels are native to North America. Which of the following best explains the morphological similarities between these two species? a.The similarities in traits indicate the species are the result of divergent evolution from a common ancestor that had the same traits that these two species share. b.The two species evolved as the result of two separate bottleneck events that reduced the existing populations to a few individuals who happened to have the same traits. c.The…arrow_forwardHuman embryos have tails which become tail bones before birth.
