Question

Skin color in humans is an example of an evolutionary trade-off: a situation where a trait that is an advantage in one context is a disadvantage in a different context. Darker skin protects DNA from damage due to ultraviolet radiation (an advantage) but makes it harder for the body to produce vitamin D (a disadvantage). Based on what you’ve learned, which of the following describe other examples of evolutionary trade-offs? Select all that apply.

A. Some genetic variations that protect humans from malaria, a disease transmitted by mosquitoes, also cause
the blood disease thalassemia.
B. Some garter snakes have mutations that make them resistant to a toxin found in their prey, rough-skinned
newts. Snakes with these mutations move more slowly and may not be as good at hunting or avoiding predators.
C. Alleles that caused the loss of body hair allowed humans to lose heat more easily in hot environments. This in
turn helped humans walk and run for longer distances to hunt large animals.
D. The common Mormon butterfly is not toxic to birds and other predators. Some common Mormons have
genetic variations that make them resemble toxic butterflies, which deters predators. In places without predators,
common Mormons with these variations don't live as long as other common Mormons.
