Which of These Traits are Explained by Convergent Evolution

Question

Which of these traits are explained by convergent evolution?
A) sickle-cell anemia in areas where malaria is common
B) light skin color in many northern populations
C) short stature in natives from the island of Puka Puka
D) red hair among people of Irish descent

Accepted Answer

Convergent evolution refers to the process where different species independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. Light skin color in many northern populations is an example of convergent evolution, as it evolved independently in different populations to adapt to lower sunlight levels for vitamin D synthesis.
