According to the theory developed by charles darwin, what process causes organisms to develop traits that them adapt to changes in their environment? a. homeostasis b. artificial selection c. succession d. natural selection

The correct answer is D. natural selection.

Natural selection is a key of the Darwin’s theory of evolution. It explains that the frequency of many traits change in a population. Natural selection is a gradual process by which traits in a population become common in every individuals. It trait allows the population to survive and reproduces successfully. For the operation of natural selection individual should have variation which is heritable. This will be better for the utilization of resources.
