What factors caused the correlation between the reduction in skin pigmentation in humans and migration of human populations away from the equator? The exposure of human populations to predators only common to the polar regions caused them to adapt by camouflaging better with the environment. The exposure of human populations to less UV light required a reduction in melanin to produce more vitamin D for healthier bones. The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin. The exposure of human populations to new diseases common to the polar regions interferred with melanin production causing lighter skin.

Human populations living in countries in the northern latitudes, such as Finland, have a lighter complexion than people living in the tropical countries. What do you think is the reason for this difference?
How is the diversity in human skin color related to human environmental adaptation?

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.
When we are underwater for extended periods of time we see that our fingers and toes become wrinkled as a result of that exposure. One hypothesis for this is the increased folding of the skin is a an ancestoral trait intended to increase grip on wet surfaces under the water. What structure of the integument causes the formation of ridges in our skin that result in finger and toe prints?
Explain the roles of Vitamin B and Vitamin D in the evolution of skin color. Use appropriate anthropological terms (such as "natural selection" and "phenotype") Be sure to discuss both Vitamin B folate and Vitamin D as they have different effects?
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.
According to the video “The Biology of Skin Color”, how does UV exposure vary throughout the world? A. The UV rays are the same at the equator and the earth's poles B. There are higher UV rays near the equator and lower UV rays towards the north and south poles C. UV rays don't vary across the globe D. There are lower UV rays near the equator and higher UV rays towards the north and south poles
