Depends on how you define species.
The way I see the future of Human Evolution is this: the human race will continue to manipulate our genes to advance ourselves, eventually incorporating more and more artificial technologies (computer chips, etc.), eventually to the point where we are no longer "human" as we know it today.
Genetic makeup could be different from how we know it today as well; perhaps if you had a strictly "robotic" type of alien race, there would exist it's own code to reproduce, similar to that of DNA, simple instructions...
