So far, I gather, the argument here revolves around the evolutionary future of adaptation and change. You're right...we can't deny the context in which adaptation is engendered, but can't we speculate about the possibilities and consequences of adapations to our ever changing evironments? And thus prepare for change (after a fashion, I admit). One of the consequences of technology is a change in learning methods. An earlier post here commented upon the signals we insert into text to comunicate various and subjective meanings: emoticons, abreviations, etc. We are using a different system of signs to communicate through technological means than we did 20 years ago. Does this return to a dependence on imagery to communicate the nuances of meaning support the theory that we are mismatched hunter/gatherers who have not yet caught up to our ever changing evironment?
