The ecological and environmental factors have the greatest potential to affect the evolutionary future of species like chimpanzee, gorilla, howler monkey, tarsier, ring-tailed lemur, or one of the many other nonhuman primate species. Introduction: The primates are the best one to classify as the order of mammals. They are defined on the basis of various evolutionary trends as they invest as a great time with their young ones and they have a highly flexible diet. They are evolved from the ancestor lived in the trees of the tropical forest.

Question

The two primates shown below both exhibit large eye orbits. One is a tarsier, the other is an owl monkey (the only nocturnal platyrrhine). Why do these primates share the trait for large eyes? Mark the best answer. Group of answer choices Random mutations, since having large eyes is abnormal in these species of primate. Convergent evolution, since both separately evolved large eyes to adapt to a nocturnal activity pattern. Both inherited this trait from their common ancestor, which was also nocturnal with large eyes. Unclear, cannot determine from the information given.

Choose all of the correct statements about complex adaptations: Complex adaptations might evolve through a combination of of gene recruitment and promiscuous proteins. The parts of a complex adaptation may have evolved for a different function originally. Complex adaptations require all parts of the adaptation to evolve simultaneously. Complex adaptation do not evolve by natural selection. Complex adaptations are composed of multiple, different traits, such as behavior and physiology. Complex adaptations are 'irreducibly complex'. Complex adaptations are the result of parallel evolution. omplex adaptations always take thousands of years to evolve.

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.
