Aren't you taking quite a biologically-restricted view of evolution, there?
Evolution isn't a biological concept, it's a systems concept. It works exactly the same way when looking at biology when it does looking at markets, or culture.
Doesn't having glasses make it easier for people to design and build, or find and purchase, hearing aids?
We can't turn off the urge to sleep. Could this be an argument that it's possible that there might be other urges which are genetic and reason can't override?
We can only partially turn off the *urge* to hunger, sleep, pain etc., but can more easily stop associated behavior. For example we can force ourselves to not eat despite hunger, stay awake despite sleepiness, not behave differently when in pain despite a surgeon cutting us open without anesthesia, etc..
But, it is essentially impossible to turn off the tendency to mental retardation in Down's syndrome and Angelman's syndrome (genetic disorders), for example. So differences in genes can substantially control our urges and can make it substantially more difficult to reason, think, and control our own behavior if we have the wrong ones.
Ultimately our ability to increase knowledge will diminish the power that genes obviously have now, by for example allowing us to correct genetic disorders.
