Answers. It was Charles Darwin who highlighted the reproductive advantages of environmentally adaptive traits. One of the most important naturalists, he studied evolution and is the one who devised the theory that we and monkeys have the same ancestor.
The functional definition allows us to identify adaptive traits, while the historical definition allows us to identify adaptations. Adaptive traits are those that increase the fitness of an organism [in a given environment]. Adaptations are adaptive traits that got selected for and remained. To understand the difference: vestigial organs are adaptations, but they are no longer adaptive. In other words, they were adaptive at one point and got selected for, therefore they are adaptations.
