Regarding the evolution of the mammalian inner ear, the above diagram shows:A) the co-option of jaw bones (colored) for use in hearingB) the loss of jaw bones (colored) and the origin of de-novo hearing bones C) the evolution of synapsids, which have little to do with mammalian evolutionD) the results of a population bottleneck which led to the fixation of odd alleles for ear development
The digger bee’s “postcopulatory courtship” consists of elaborate tactile stimulation that the male provides his partner after she has accepted his sperm. Why is this behavior a Darwinian puzzle, and what might its adaptive value be? Dont' write from any online source.
Among a population of tadpoles, the correlation coefficient for size atmetamorphosis and time required for metamorphosis is −0.74. On thebasis of this correlation, what conclusions can you draw about therelative sizes of tadpoles that metamorphose quickly and those thatmetamorphose more slowly?
Gould wrote his passage as a criticism of his fellow evolutionary biologists. Of the following statements about the human eye, which would those biologists agree with the most? A. The eye has lost its purpose and it's obsolete. B. The eye is a perfect fine-tuned machine well suited to its purpose. C. The eye has a use, but it was not evolved for that use.
Bipedalism has many selective advantages. However, there is one disadvantage to walking on two feet: giving birth to an offspring with a large head through a small pelvic opening, which is necessitated by an upright posture, is very difficult. This situation results in a high percentage of deaths (for mother and child) during birth compared to primates. How do you explain the selection of a trait that is both positive and negative?
Prey detection can be a challenge in the different environments. Describe how the challenge of detecting prey in any given environment (water, air, earth) has been accomplished in three (3) different Orders of herptile (your choice, but include at least one Order from each taxaonomic Class). Be sure to explain how that trait overcomes some challenge posed by the environment.
Use Verbal description of results from graph and then Interpret the graph for Pre camouflage sccenario in foraging lab. The interpretations must include Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: In the scenario involving prey camouflage, the hypothesis is that species taking extended periods to forage, especially novice foragers, would be at heightened risk of predation due to their prolonged exposure.
Ancestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.
Modern sponges produce microscopic spicules (right) to deter predation but, as the earliest animals, they existed before any predators evolved; how might biologists interpret this observation? A. Spicules were probably absent in the earliest sponges and evolved later as predation began. B. Spicules performed other tasks in early sponges, possibly structural support, and were later modified for defense. C. Spicules were present in some sponge species and absent in others; predation became a selection pressure that eliminated some species entirely. D. All of the above are valid hypotheses.

If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: n the scenario involving prey camouflage, the hypothesis is that prey species will exhibit seasonal variations in their choice of beans for consumption based on the available background vegetation, with a preference for pinto beans during the first half of winter when they are more visually similar to their surroundings and a preference for pea beans during the second half of winter when they better match the changing background vegetation.
How would you apply this in a Lamarckian explanation? Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.

While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to grasp branches while moving throughout the trees in its enclosure. This is most likely a(n) A. New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primates hands and feet B. Old World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet C. New World monkey, because these are the only monkeys that live in trees D. Lesser ape, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet
