Evolution happens very slowly, but almost all species are still evolving to aim to be best adapted for their environment. It’s hard to predict how we will evolve in the future, especially as we don’t know how the climate on the Earth is going to change over the next hundreds and thousands of years.
There are some people who say that with modern medicine and so on we are messing with evolution. Evolution works by survival of the fittest, so if your not fittest (and by that I mean most suitable to the environment of the time) you get ill, or eaten, or run over by a bus and so removed from the gene pool as they don’t have kids. What with being dead and all.
We are still evolving, just in another direction. Different factors are becoming important as to who ends up having children, so different genes propagate other than who fastest or best at avoiding big things with sharp teeth.
