No one will ever say that their own generation are no longer human so do you think that in many, many years from now, we may be classified as a new species? How long would you think that it would take for us to evolve?
A new human specy will come from Africa again and will take over and we will extinct as the other Cromangons Neondertals homoabilis .... We are not going to evolve, we are going to disappear
All species evolve all the time, albeit at different speeds depending on environmental changes and mortality rates.
Species don't change from one generation to the next any more than you can select a particular day that you went from being an infant to being a full-grown man.
Speciation takes many hundreds of thousands of generations.
All animals only evolve when they need to adapt to a change in the enviroment. So next time our enviroment changes largely we will evolve (but it takes thousands of years)
Our next evolution would probably be losing our vestigal organs (the ones we dont use)
