Question

what does natural selection cause?
a. evolution
b. conditioning
c. limitation
d. differentiation

Explanation:

Natural selection is a key mechanism in biology. It acts on the variation within a population. Organisms with traits better suited to their environment are more likely to survive and reproduce. Over time, this leads to changes in the population's characteristics. These cumulative changes result in evolution, where species adapt and new species can arise. Conditioning is related to learning (like in psychology), limitation is a general term not specific to natural selection's main outcome, and differentiation (in a biological context) is more about cell - level changes rather than the overall process caused by natural selection. So, natural selection causes evolution.

Answer:

A. Evolution
