Question

Quizplus · Accepted Answer

An adaptation is a trait that is currently beneficial to survival. It may have been beneficial in the past, but the key feature is that it currently helps an organism survive and reproduce. Traits that are of no advantage to survival or may be beneficial in the future but not currently are not adaptations. An environmental change may select for certain traits, but the adaptation is the trait itself, not the process that led to its selection.
