OK, I read it and found that in a rather simplistic alife simulation
a structure evolved in a 16-neuron net can be co-opted for a very
similar purpose (finding a new variant of abstract food after the
one it has adapted to has disappeared). I would still call it an
adaptation. We use our brains to send e-mail even though it
obviously wasn't an evolutionary adaptation for that purpose. Would
you call the human brain an exaptation?
