Which evolutionary force is likely responsible for the increased incidence of xeroderma pigmentosum (extreme sun sensitivity) in some Navajo peoples and describe how it came about.

Answer each statement with true or false: a. Many North Americans ethnocentrically assume that all societies equate biological ties with relatedness and kinship. b. Among the Inuit, the most important part of a person’s identity lies not in their biological family, but in their name, which is often the same name as a deceased relative, which links them spiritually to that person. c. Traditionally, the concept of machismo is associated with adultery, a lack of emotional openness, drinking to excess, and aggression. d.

From the movie what Darwin Never Knew. List 5 things that make humans different from other apes and other species. Why did parallels between humans and apes make people angry?

How does skin cancer not exert enough evolutionary pressure to account for darker skin in humans? How does folate deficiency exert enough evolutionary pressure to account for darker skin in humans? What is one indispensable function of UVB rays in the human body? How does this exert evolutionary pressure on human skin color? Briefly describe the 2 reasons why the Inuit people exhibit somewhat darker skin levels than would be predicted given the UV levels at their latitude.  What theory do the authors propose for why women generally have lighter skin than men? Briefly explain why skin color is described as “one of the least useful characteristics in determining the evolutionary relations between human groups”?

Based on everything that you have learned so far, provide an explanation for how the different shades of skin color from pinkish white to dark brown evolved throughout human history.

Which of the following is an example of a mutation in the MC1R gene that is associated with lighter skin pigmentation in humans? a. I120T b. V60L c. D84E d. R163Q

Imagine the following: A disorder that leads to nearsightedness (difficulty seeing things at a distance) is caused by a genetic mutation. On a small island in the pacific, nearsightedness was particularly harmful to people living there because they relied on sight to interpret their surroundings. In the 1600s, a huge storm killed many of the people on this island. Before the storm, 0.1% of the people had this mutation impacting their vision. Of the 50 people who survived the storm, 2% were nearsighted. Within a few generations, 10% of the islanders were nearsighted. Which is the likely evolutionary force behind this observation? Have the student to explain the reason

Please answer fast According to modern sociobiological theories of about warfare which one of the following is not one of the three stages in the evolution of warfare? a. Primitive hominids formed small bands for defense against predators, thereby developing a high a high degree of group cohesion, male bonding, and male aggressiveness. b. Hominid bands turned increasingly to the hunting of game animals, for which cooperative and aggressive tendencies proved advantageous. c. At some point, the primary purpose of group organization became defense against other bands of the same species, followed by the balance of power and escalation in the group size and organization to achieve a margin of safety. d. Hominid bands resorted to intraspecific aggression and cannibalism in an effort to cope with chronic food shortages.
