Exaptation is a process in which the organism acquires for its function that was not originally adapted or selected through natural selection. The evolutionary trait that is evolved to serve a particular function of an organism, but subsequently the organisms use to perform another function is termed as the exaptation. This exaptation trait is most common in anatomical and behavioural properties of organisms.
