Question

HIV has become an important source of mortality for humans. If AIDS persists as a major factor for humans for many generations in the future, natural selection theory predicts that _____.

Answer 1

Answer:

Any heritable traits that help humans survive and reproduce in the presence of AIDS should become more frequent over time.

Explanation:

The theory of natural selection is defined as the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This means that, in this case, people who inherit a trait in their genes that allows them to resist the HIV virus, will be able to survive better and have children.

Unfortunately, there is no record of such a trait existing, and in this case, there is no kind of natural selection that can arise if every human becomes infected.
