"Exaptation" Pronounce,Meaning And Examples

"Exaptation" Meaning

Exaptation is a term used in biology and evolutionary theory to describe a feature or trait that originally evolved for one purpose but later became useful for another purpose. In other words, an exaptation is a characteristic that was not initially designed for its current function, but has been co-opted for that purpose over time through the process of evolution. This can occur when a feature that was originally adaptive for one reason becomes useful for another reason in a new environmental or ecological context.
