Future of human evolution

The unique sentience of human beings offers a mind-bending perspective on human evolution.

Our intelligence allows us to drastically alter what would be considered the natural course of things. However, why should one consider our actions to be unnatural if we ourselves are born of nature? If our sentience gives us the ability to alter the course of our own evolution, would that be considered evolution or something else entirely?

Discuss.

Sentience, intelligence...or what not has only a fraction to do with evolution. Many mutations have come to pass due to necessity such as reproduction, etc. However, do not forget that environment and mobility also play a factor in evolution. Reptiles that used their bodies more than their legs lost their legs and became snakes due to the necessity of the environmental coalescence. So even if you were to know what evolutionary path you wanted, knew what it took to get you there, you'd still run into environmental variables that degrade the clarity of the evolutionary visualization. If anything, this alone should assist us in our understandings OF evolution.
