Ok, my bad, contrary to expectation you seem to be implying the evolution takes away certain characteristics that are not used together with improves others which are used which isn't necessarily accurate.
Yep that's true... As in, to what I learned from school, the currently accepted theory of evolution is not that one which states that if u don't use an organ it will gradually disappear, but it is that one which states that the individuals that develope (sort of randomly) the characteristics that are best for survival will be the ones that will survive and pass their genes; thus the existence of our organs not relaying in the use we put on them.
Regarding the topic Doktormartini I think that the theory is quite non-interesting and quite pointless and that you should maybe read some more valuable pieces of literature with more important meditations about the world and reality in terms of epistemology, metaphysics and (to a lesser extent though) ethics; because in my oppinion the world works in such a way that it is impossible for you to be happy unless somebody else is suffering at the same time somewhere, and nothing can be done about that....... or at least nothing as easy as reducing the production of food.
