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_forwardDevelopment 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_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
- Chimpanzees 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_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_forwardHow would you summarize your understanding of this topic now? What species of hominin do you think had enough of these fundamental qualities that you would call them human? What traits are present in this species that lead you to this conclusion? There are no right or wrong answers, just talk about the traits you think are key to being human and what species has enough of these that you think of them as human. please someone answer this is Anthroarrow_forward
- whose DNA sequences differ between humans and apes, these differences have not been correlated with the huge growth of human brains.arrow_forwardOne compelling piece of evidence for human evolution is the fossil record, particularly the discovery of transitional fossils like Australopithecus afarensis. Lucy, discovered in 1974, provides an essential link between us humans today and our ape - like ancestors. Her head skeleton, especially the pelvis and leg bones, indicates that she walked upright, a key trait distinguishing early hominins from other primates. This evidence is compelling because it directly shows us physical adaptations in ancient species from millions of years ago that align with the evolutionary theory of bipedalism. Supporting this theory the gradual changes observed in the fossil record, from ape- like traits to more human-like features, offer concrete, sequentially proof of how humans have evolved over the years.arrow_forwardThere 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_forward
- If 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_forwardParabiosis research into aging demonstrated which of the following to be true? - Future cures for aging will require young humans to be permanently attached to elderly patients -Neurogenesis only occurs in heterochronic animal pairs -There are some factors in young animal blood that improves cognitive performance in older animals -Only heterochronic animal pairs show improvement during cognitive tasksarrow_forward
