Question

Quizplus · Accepted Answer

Natural selection acts upon populations containing individuals with genetic differences, favoring those individuals that are better suited to their environment and increasing their likelihood of passing on their beneficial traits to the next generation. Continental drift and weather do not directly result in evolutionary changes, although they may indirectly influence them. Mutation is a source of genetic variation, but evolutionary changes only occur when natural selection acts upon the resulting genetic differences.
