The underlying principle is that genetic mutations do occur and can be passed on to offspring. But, is it reasonable to suppose that humans will continue to evolve over any length of time?
The problem I see is this: in order for humans to evolve as an entire race, the necessary genetic changes would have to occur in all humans that have children within a given generation, so that those changes can be passed on to the entire population of future generations. However, such a widespread genetic change affecting everyone the same way is very unlikely. There may be some who inherit certain mutations, but these individuals are just as likely to mate with other humans that didn't receive the genetic change. The end result is that isolated genetic mutations are not going to have much of an effect on the world's population as a whole.
If the same concept is applied to our ancestors, how likely is it that some descendants would become humans while others became apes?
