At least three hemoglobin alleles in human populations alterhemoglobin structure in such a way as to impair the transportof O2 by the blood but enhance resistance of red blood cells toparasitization by malaria parasites. Explain how such allelesexemplify pleiotropy, and discuss whether such alleles couldlead to nonadaptive evolution of blood O2 transport in certainsituations.

Which of the following statements best describes the evolution of globins? O One gene repeatedly mutated over time to ultimately yield multiple forms of the globin protein. O The onginal globin gene was duplicated, and the copy mutated to yield a new globin; this process of gene duplication and mutation occurred repeatedly.

Snakes evolved from ancestors who had the ability to walk. Some snakes, in fact, still have small pelvis and leg bones that are remnants from this ancestor. What are these caled? Vestiglal structure O Homologous strucre O Sympatric structure O Molecular homology In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. Of what is this an example? Founder effect
The presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces. A model of the evolutionary relatedness between these species is represented in the figure. G. humeralis Can adhere O Cannot adhere 2 O G. concinnatus O G. antillensis Which of the following statements is an accurate interpretation of the labeled branch points on the model? Location 1 represents the common ancestor of only two of the three species.

How did all the different body types in the Cambrian arise so quickly? O Hox genes had evolved that determine and allow for the diversification of body plans. Because Hox genes hadn't evolved yet, there was a lot of flexibility in how body plans could develop. O There was a genome duplication event that led to the diversification of body plans. Enhancer driven gene expression had just evolved, which made it easier to vary body plans. Toing wheroptiones 29
56) The human body contains structures that are needed for survival, or in the case of vestigial structures, were needed for survivalL Wisdom teeth, seen here, are vestigial third molars. Human ancestors had larger jaws with more teeth. Over thousands of years, man no longer needed the third molar, and they became the source of dental problems rather than an aid in survival How does this vestigial structure support the theory of natural selection? ht ing The size of man's cranial cavity evolved. With increased cranial cavity size, the size of man's brain also grew. This resulted in a smaller jaw and no 14 A) room for the third molars. Agriculture and the use of fire changed what and how man ate and need for these teeth diminished over time. Jaw size and shaped evolved and there was insufficient room for the third molars. he B) The climate on Earth changed from very cold to tropical The tropical climate on Earth lead to a change in the diet of humans and that lead to the need for sharp,…
The lung was the first air breathing organ (ABO) that evolved in ancient fishes, but after fish evolved the swim bladder to aid in controlling buoyancy, this latter organ was often converted into an ABO when fish were faced with positive selection for air breathing. So much so, that in groups of fish that evolved before 150 MYA, this is the only type of ABO found. However, air breathing evolved many more times in more recent groups of fishes, but interestingly, now the swim bladder is NEVER used as an ABO and instead all sorts of different body parts are used (e.g. mouth, stomach, intestine). Why did the original swim bladder make such a good target for evolution to turn it into an ABO? What happened in modern fishes to change this? A new device is on the market that senses pulmonary interstitial fluid pressure (around the lung cells) in patients and relates that information to the patient’s health care provider.
