Adaptive evolution
A) is large-scale movement of a single species over a new geographic area.
B) occurs when a more adapted species causes the extinction of a less adapted one.
C) is the process by which natural selection improves the match between an organism and its environment over time.
D) is an increase in the adaptiveness of many species that have already evolved.

Question

Quizplus · Accepted Answer

Adaptive evolution is the process by which natural selection improves the match between an organism and its environment over time. It involves the gradual genetic changes in a population that lead to an increase in the frequency of traits that improve survival and reproductive success. This can result in the development of new species or the adaptation of existing ones to new habitats or ecological niches. A and B are incorrect as they do not accurately describe adaptive evolution. D is incorrect as it implies that many species are evolving in the same direction, which is not necessarily the case.
