Chapter 17, Problem 4CT
Summary Introduction
To test: The given hypothesis for evolution of human traits arisen by sexual selection.
Concept introduction: Sexual selection is the process or a form of natural selection where a member of one sex chooses its mate from the opposite sex (intersexual selection) and to mate with the opposite sex, it should compete with the member of the same sex (intrasexual selection). Sexual selection leads to the evolution of some traits that help in sexual attractiveness among the partners.

Some human traits may have arisen by sexual selection. Over thousands of years, women attracted to charming, witty men perhaps prompted the development of human intellect beyond what was necessary for mere survival. Men attracted to women with juvenile features may have shifted the species as a whole to be less hairy and softer featured than any of our simian relatives. Can you think of a way to test this hypothesis?

- Humans as individuals have a number of disadvantages compared to other animals. For instance we are not very fast, strong, cannot see well in the dark, have a poor sense of smell and hearing compared to other animals, and we are not very good climbers. With all of these disadvantages how is it that we have been so successful? Shouldn't we have gone extinct as other humanoids such as Homo erectus? Discuss why humans have beaten the odds and are so successful.arrow_forwardOnly when extensive genetic data became available were scientists able to definitively resolve the relationship between humans, chimpanzees and gorillas. Explain why the relationship between these three species was a particularly difficult challenge to solve. Important point. Explain why the relationship between these three species was a particularly difficult challenge to solve?? I don't really see that in your answer. I posted this question 3 times but answer given me wrong.arrow_forwardFrom the movie what Darwin Never Knew. During the time of Darwin how were the prevailing views of how species were created/ behaved different from Darwin’s observations and view of nature? What are hox genes and what do they have to do with limb formation?arrow_forward
- Development of an animal is controlled by the genes that are expressed during development. What roles have been proposed for Hox genes in the evolution and morphology of animal species? Group of answer choices 1. Variation in the Hox genes may have spawned the formation of many new body plans. 2. All of these descriptions are correct. 3. The number and arrangement of Hox genes varies among different types of animals. 4. Increases in the number of Hox genes may have led to greater complexity in body structure.arrow_forwardNeanderthal fossils were first discovered in the nineteenth century. Study of their morphology suggested that Neanderthals were more closely related to humans than any living species of primate was. Much later, it became possible to sequence DNA from Neanderthal fossils and compare the sequences to those from other primates. Did the results confirm or refute the earlier conclusions based on morphology? Explain.arrow_forwardChimpanzees and humans obviously look and act very differently, but their genomes are remarkably similar. What types of mechanisms could explain how small differences in genotype can result in such large differences in phenotype?arrow_forward
- Hi! I am interested in getting some help with this question. This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena we have discussed this semester, 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? (b) This spectacular tail presumably attracts predators; why hasn’t natural selection acted to reduce it or camouflage it?arrow_forwardwhose DNA sequences differ between humans and apes, these differences have not been correlated with the huge growth of human brains.arrow_forwardNeanderthals are recognizably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. They shared Europe for 10,000 years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthal has generated much debate. Why did Neanderthals become extinct? State at least two major factors to explain their fate.arrow_forward
- There is no concrete evidence of which early hominin was our direct ancestor, as fossils do not contain genetics. Overall, the Australopithecines are the "missing link" bridging our ape to human transition. Each species, and there are a few, includes a combination of traits considered more ape-like or more human-like. How does this affect society feelings/views/ideas about early human evolution and what the "missing link" should or should not be.arrow_forwardIf dogs became self-domesticated through a commensal relationship with modern humans, which of the following might we expect to find as evidence? Dog domestication pre-dates deliberate human domestication of other plants and animals Domesticated dog remains associated with other hominins, like Neanderthals and Denisovans Cave paintings depicting the gradual change from wolves to dogs over thousands of years Genetic evidence that humans were trading dogs breeds over long distances Woven reeds used as dog collars and leashesarrow_forwardAccording to "Homo erectus – The First Humans”, why is it interesting that Homo luzonensis was found on an island? A.The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island B.The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were there C.The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them D.The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raftarrow_forward
