Evolution, yes but how?

[Colbaker]

Ok, most of us take evolution for granted, My main issue with it is "how does anything actually evolve?" is there a separate power that we cannot see that decides a certain animal is getting eaten to much by it's prey so does it decide to start the change of this animals skin to camouflage said animal? Or does the species itself have some sort of unconscious connection that detects their numbers falling and decides to adapt themselves for protection?

Also take us humans, It is said that we have evolved from living in trees because our environment changed and their were less trees around, what process actually caused this? I can't tak th answer "because we did" there has to be a process going on that decides to start evolving.

It makes sense really, I probably should have thought about my original post before posting but think this thread has gone further than i expected.

Another thing regards to evolution, If it is purely down to reproduction then logically the "fittest" (for want of a better word) people will be the one's who have the largest family's, These do tend to be the Dosser's who have nothing better to do than pro-create and unfortunately don't seem to have the intelligence to use contraception, Also certain races and religions have large family's so these will likely be the "fittest".

Also now we have to take into consideration Women, Before the strongest Man, the best hunter will get the choice of Women, If they are opposed then they fight and the winner then gets the choice of that women so that child is likely to have better genes, These days women make the decisions and a lot of women tend to choose weaker more feminine men, does this mean the human race is devolving itself into a week society reliant on other people?
