Like with engines, tuning for performance means sacrifices in reliability and service intervals.
—Like with engines, tuning for performance means sacrifices in reliability and service intervals.—
To use the same analogy, I was told by someone here that the reason car engined last so long nowadays is that all engines are the equivalent of what, in the 60’s we called “blueprinted”.
IOW, man was designed as a very high performance container for our souls and the design can not be improved upon. Or at least it was designed so it could not be improved upon.
I sometimes wonder how the four chamber heart came about and what a stroke of genius. ;-)
In evolutionary biology it is called “antagonistic pleotropy”.
As you said “Like with engines, tuning for performance means sacrifices in reliability and service intervals”.
Also it is not the only thing in our “car” consuming energy.
The more energy the brain consumes the less there is for the musculature.
Larger brain size at birth means higher maternal mortality and infant mortality.
Besides, what is the selective pressure towards higher intellect. While people do mate assortively for high intelligence - producing high IQ kids usually - the less intelligent in our society ALSO mate assortively - and tend to have just as many (or more) children.
