We are still evolving, and science is so developed that can predict the evolution of a longer period. Let us see how the scientists see the human in 1000 years from now.
Besides that we will be higher and we will have more developed senses, we will probably be more resistant to diseases due to the changes in our DNA. Interestingly, after the settlement of Mars, the local people will begin to evolve in a different direction. They will be higher due to the lower gravity and their pupils will be wider due to the lack of light.
