Question
Chapter 10.4, Problem 1TC
Summary Introduction
To determine: Whether the risk of skin cancer have selected against pale-skinned people in equatorial regions.
Introduction: Natural selection denotes the process of evolution where organisms possessing favorable traits become more successful than other organisms. These traits are also passed on to the successive generation by the process of sexual reproduction.

- According to the video “The Biology of Skin Color”, why is UVB critical for humans? A. It helps our bodies break down Vitamin D, which can be toxic to our bodies. B. It helps our bodies synthesize Vitamin C, which we need in order to absorb calcium in our diet. C. UVB is not critical or useful for us. D. It helps our bodies synthesize Vitamin D, which we need in order to absorb calcium in our diet.arrow_forwardAccording to Nina jablonski's research dark skin is adaptive because it protects from __________ at low latitudes. Light skin is a derived trait at high latitudes to allow for __________ production.arrow_forwardAccording 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 polesarrow_forward

- Give 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?arrow_forwardHow does skin color throughout the world match up with UV exposure? A. Darker skin is usually found in high UV areas while lighter skin is usually found in low UV areas B. UV rays are the same throughout the world, so there is no pattern or correlation with skin color C. Skin color throughout the world does not match up with UV exposure D. Lighter skin is usually found in high UV areas while darker skin is usually found in low UV areasarrow_forwardTwo brown eyed parents have a child with blue eyes.

- 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.arrow_forwardWhy is it that the evolution of skin color is considered a case of natural selection? Group of answer choices A- Because different alleles in skin color genes lead to differences in skin color B- Because differences in skin color lead to differences in number of children in different environments C- Both D- Neitherarrow_forwardWhich 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 polesarrow_forward
