[QUOTE="bunkster"][QUOTE="Mr_sprinkles"][QUOTE="bunkster"]You misunderstand me, I know the difference between knowledge and intelligence. I was refering to the point that we would never have raised our intelligence from our ape ancestors if it wasnt possible to develop it as a species. The apes did it by working with tools and pushing their own intelligences to the limit for the sake of improved survival.

You misunderstand the workings of evolution. It had nothing to do with the apes pushing their own intelligences, it's just that the ones with "big brain" genes were able to breed more. Evolution is nature. You're worrying about nurture.
Then a species would never become greater than the ones with the best genetics.
this would be true if there were no such thing as mutations. Mutations in DNA can be beneficial, neutral or detrimental. The beneficial ones that somehow improve upon what's there can increase a creatures ability to produce offspring, (living longer, getting more food, better protecting young etc)the neutral ones are free to accumilate until something useful/bad happens with them, and the detrimental ones are often removed from the gene pool because of the disadvantage it creates.
So yes, things will always be limited by the genes, but the genes will always be changing and mutating, eventually creating better genes. The increase in intelligence of apes is to do with the increase in size of their brains due to genetic mutations and alterations, and through the process of natural selection.
It was the increase in brain size that allowed greater capacity for using tools and solving problems. Not the other way round.
I admit that alot of this is true, mutation is a large factor in the evolutionary process. Still, mutation only works if combined with natural selection...if the mutation isnt useful enough to cause an increase in survival rate than the mutation will just die out. So your telling me things like skin pigmentation are necessary for our survival?
Interaction with the enviroment can also bring about evolutionary change.
