- Explain the function of large male canines in a sexually dimorphic primate species: Examine the illustration below and answer the following questions: a. Compare fore-limb (arm) length to hind-limb (leg) length in this primate. Are they the same or different? If different, which is shorter and which is longer? b. What is the locomotor pattern of this primate? c. This is a/an (circle the correct answer) (1) prosimian (2) monkey (3) apeYou want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page. CHARACTER SEXUAL DIMORPHISM MALES FEED YOUNG Cassin's Vireo No No Red Fox Sparrow Cape May Warbler Cedar Waxwing Golden-Crowned Kinglet Pyrrhuloxia Yes No No No No Yes No Yes Yes No California Gull No Yes Note: This data is fictional 5) Which of the hypotheses in part 4 is consistent with your analysis? Explain why in a brief paragraph.Is this evolutionary conservation of the pecten structure evidence that natural selection might be maintaining the pecten in its present form in many bird species? Is this theory one that suggests the pecten has a significant adaptive function in birds? Do you believe that experiments might be useful in determining the adaptive function of the pecten if it indeed serves an adaptive function? Outline a simple experiment to see whether the presence of a pecten in the bird's eye is an adaptation.
- 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…2 3. Explain how human hunting has affected the traits of the African elephants. Explain why being a tuskless male has become a successful adaptation.Animals have evolved a range of strategies to successfully respond to threats and challenges. One of these strategies is the ability to learn. As we discussed, not every animal can learn and there are clear costs and benefits to this strategy. Suggest one benefit of the ability to learn and one potential cost. Briefly explain each. (1-2 sentences for each) Since learning is not universal, under which circumstances would it be most likely be a successful strategy? We discussed a framework that examines the influence of predictability on the success of learning ability. Describe this framework. Make sure you discuss all the available conditions and clearly state under which we would expect learning to be successful and where we would not expect it to be successful. What would be an alternative strategy to regulate behaviour when learning is not suitable? Briefly explain your choice. (2-3 sentences)

Put emphasis on the importance of adaptation to the environment and the development of these traits.
- Explain the rationales behind ecological and social models of the evolution of primate cognitive abilities. References are the books "Primate Behavioral Ecology" by Karen Strier and "Planet Without Apes" by Craig Stanford5c) Do you believe that experiments might be useful in determining the adaptive function of the pecten, if it indeed serves an adaptive function? Outline a simple experiment to see whether the presence of a pecten in the bird eye is an adaptation.1) choose a unique behavior or a defining biological feature of the animal; 2) describe at least one distinct ecological condition(s) affecting the species/population (e.g. habitat type where they are found; food resource or prey item; etc.) 3. explain why these ecological and physiological trait(s) are vital to the survival and persistence of the animal population.
