Human evolution will continue to occur only in a different series of events. With the advancement of our genetic intelligence we'll be able to advance ourselves physically through our own doing but the evolution of our minds will continue to advance.
I've read that our genetic makeup gives us the ability to make Vitamin C internally (As our bodies do with Vitamin K) but that ability is turned off. We have all the structures to allow it but it doesn't function. I suspect this is most likely because the change in diet we had long ago from the mostly meat eating/hunter diet to the agricultural/farming diet. I think that if we continue down the path we're on different parts of our genetics will go through the same thing. They'll be dependant on other kinds of intake (Food, drugs, etc...) to assist us in what our bodies currently do by themselves from birth. I see the future of humanity being dependant on our own tehcnology.
