Step by step
Solved in 3 steps
- The images below depict a female (left) and male (right) primate of the same species. Based on these images, would you agree that a high degree of sexual dimorphism is present? If so, what traits indicate this? Mark all that apply. Group of answer choices Yes, a high degree of sexual dimorphism. No sexual dimorphism - these would be considered an example of sexual monomorphism. Male has much larger canines. Male has a sagittal crest Male is much larger in overall sizehttps://www.youtube.com/watch?v=FVuNTiqHys0 Do you think that animals like Koko who has the capacity to communicate to humans are additional proofs that chimpanzees and humans may have come from the same ancestors as Charles Darwin postulated?As you know chimpanzees in neighboring groups in the forest show 4-5 times as much genetic difference as any two human populations. Is it reasonable to expect that trait that show genetic variation in humans, such as the structure of the hand and the brain, might show significant variation between chimpanzee populations? Why or why not?

How can negative traits that don't show up until old age continue in populations? (Why aren't they eliminated through natural selection?) As part of answer, provide an example. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If natural selection occurs in this population, what would someone expect to see if you returned in 100 mouse generations? Describe what someone see in terms of fur colors in the population. Imagine a population of mice living in a grey, rocky environment. Some mice are grey and some are brown. If mutations occur in this population, what could someone see if they returned in 100 mouse generations, that would tell them mutations had occurred? Describe what they would see in terms of fur colors in the population, and how it would be different from what they would see in #2. If dark skin helps protect…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?
- Define natural selection using the 5 points below to explain its role in understanding primate behavior. (1) there is variation among individuals; (2) some of that variation is heritable; (3) there is always competition between individuals for resources; (4) some variants outcompete other variants and leave more offspring; (5) to the extent that the parent's traits are heritable, then a larger portion of the next generation will reflect those traits.With all the rich diversity of the monkeys, apes, lemurs, lorises we see in our world today, how has evolution shaped these differences? (hint: think mating strategies, diet, geological/climate, etc).#21 Answer the following questions about evolution. Number responses according to the questions (1-4).

- Central African chimpanzees (Pan troglodytes troglodytes) and bonobos (Pan paniscus) are two different species of chimpanzees that live in sub-Saharan Africa. The map indicates the regions where central African chimpanzees and bonobos can be found. A scientist claims that central African chimpanzees and bonobos were once a single ancestral population before evolving into two separate species. Which of the following characteristics of the region could help to explain how a single ancestral population evolved into two separate species of chimpanzees?A number of behaviors that exhibit cultural evolution, such as tool-using, also have genes that favor such learning. Could different populations of chimpanzees have different genetic predispositions to show cultural evolution?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?
