Controlling a kind of personal evolution is impossible because there is no such thing as personal evolution. Evolution is a term reserved for populations of organisms not individual organisms. Controlling the evolution of a population of organisms is possible... it's called eugenics...

Remember that the changes (evolution) starts with one being, i mean (human or animal), and then that being starts to interact in the nature reproducing him/her/it/self and transmitting the evolved genes to the newly born.
The assumption being made is that modern humans arose from a single mutation event in a single individual. Imo that is unlikely. Humans aren't prokaryotes.
More likely changes in the composition of the alleles in the gene pool as a whole resulted in the evolution of H. sapiens from H. heidelbergensis.

A single mutation event in a eukaryote organism such as a human is not sufficient to be labelled evolution. There is far too much genetic diversity. You'll have to wait a lot longer than 50 years for evolution of humankind into what can be classified as a new species.
A species is roughly defined as a group of organisms that can interbreed to produce viable sterile offspring. In other words a group of organisms have to evolve from modern humans, that can interbreed with each other to produce sterile offspring but cannot interbreed with modern humans.
