What does the fine tuning process of the human brain imply?

Answer 1

--That *efficient* or streamlined thought processes matter more than ultimate intellectual potential. With every major growth spurt after infancy the human brain *usually* prunes neurons, trims back the massive growth of the brain that started in the womb. What this means in real life terms is that as you get older, your *potential* to learn more and to become smarter declines in an absolute sense, but you end up knowing what you know much more *solidly* for the effort.

Raw intellect is traded off for *competence*. At least usually in healthy brains.

--That on a purely biological level, having the big honking brain that we do is metabolically *very costly* in terms of keeping that many specialized cells *alive*. That some attrition of the brain has to take place in order for there to be a sustainable metabolism that works for the rest of the body.

In real life terms, this would mean that we likely cannot evolve much more in terms of getting more and more brain size without *losing* something in terms of ability elsewhere. We might end up *shorter* in height, for example, or have shorter *lifespans*, if our adult brain size gets too much bigger and if we get too much smarter.

--It also implies that "No man is an island." You can *try* to live up to the old idea of the Renaissance Man and be the generalist, but the trend will always work against that. Human brain development itself favors being competent to a high degree in a few specialities that fit into a larger social picture.

In the real life sense....you do become your job. You become what you do the most, as your brain streamlines, defragments, and generally tosses out anything and everything that keeps you from being "The Man" at your One Great Thing. And this only works well when you *are* in a social construct that allows you to *succeed* this way--a society or a civilization.

I hope this helps....and thanks for your time, good Question! ^_^
