Holy cow, Dr. Bill--here's a sentence and a half, from one of the Google sites: Indeed, the chief human evolution adaptation of increasing brain size was to provide humans with the neurological room for neural plasticity based exaptation to create novel learnt functions; first linked to dexterity, language and other hunter-gatherer transmitted skills, later in the human career for modern symbolic cognitions dependent upon notation and complex urban societies such as reading.
Shanks, where are you?

Here's what I was looking for--an example: For example, the bones of vertebrates (ancestrally for mineral storage) were exapted into locomotory structures by the ancestral sarcopterygians.

Apparently, there are both physical and mental exaptations.
Oh, I just thought of one: when a part of the brain is injured or removed, sometimes what is left can take over new functions, expecially in young children.
Thanks, Dr. Bill.
