Quizplus · Accepted Answer

An adaptation is a trait or characteristic that increases an organism's fitness or ability to survive and reproduce in a given environment. This trait is favored by natural selection, which leads to its increase in frequency in a population over time. Thus, a trait that confers a greater level of fitness, relative to those who lack it, can be considered an adaptation. The other options (mutation, variation, allele) refer to genetic processes that can generate new traits, but do not necessarily imply a higher level of fitness.
