- 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 factor correlated with human populations losing skin pigmentation? moving away from the equator moving away from shaded environments moving away from mountainous environments Moving away from the polesGive only typing answer with explanation and conclusion Identify the role of natural selection in the evolution of skin color. What role does folate and vitamin D have? How do they differ? How can someone maximize folate and vitamin D levels? Does natural selection still relate to skin color in human populations? If so, how would you expect human skin color to change in human populations in the future?
- Unique traits that allow living things to survive easier are called whatWhich of the following decreases the evolutionary fitness in people with darker skin color? Assume there is no dietary supplementation. A_ Low folate in areas with high UV B_ Low folate in areas with low UV C_Low vitamin D in areas with high UV D_Low vitamin D in areas with low UVWhich factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection? the impact of UV radiation on folate and Vitamin D levels in human populations the clothing worn by humans in the early 8th century the interaction of human populations with predators in colder climates a change in the diet of human populations as they settled in colder climates
- According to the video “The Biology of Skin Color”, why is lighter skin needed in areas closer to the north and south poles where UV rays are weaker? A. Individuals with a lot of melanin would get too much UV ray penetration in their skin and they wouldn't be able to synthesize vitamin D. B. Lighter skin is not necessary in the north and south poles. C. Individuals with a lot of melanin wouldn't get enough UV ray penetration in their skin to synthesize vitamin B. D. Individuals with a lot of melanin wouldn't get enough UV ray penetration in their skin to synthesize vitamin D.scientist have long known the dogs involved from wolves. but no one knows exactly how dogs became domesticated. based on the sentences what can you infer about wolves? How is the diversity in human skin color related to human environmental adaptation?
