      Maybe, if humans survive for long enough, evolution will make us different – we are changing a little bit all the time.

      How would you like to be different? I wish I could have gills to breathe underwater, instead of having to use a snorkel on holiday.

      Evolution will eventually change us and as humans we’ve already seen a change physically due to this!

      People living hundreds of years ago used to be several inches shorter due to diet, health and genetics. Now though we are much taller and those people back then would think we were all weirdly tall if they met us!

      Also back then people had no overbites (when your top teeth sits in front of your bottom) because we have forks today when back then they weren’t very common. Cutlery selected for overbites because forks are easier to put in your mouth when you have a space between your top and bottom jaw!

      Overall I think we will change but it will be subtle like all becoming brunettes or being less hairy.

      We (as the human race) are likely to mildly change in future due to evolution. We have already evolved to be taller than they were in the Middle Ages for example. If you go in really old places, the doors are a lot smaller. This is partly to not let heat out but also because the people were smaller (though their smaller stature could be bad nutrition as well as evolution). Our evolution in future may not be in the direction you may expect as what would be good for survival in the natural world is not necessarily good for survival and breeding in the modern technological era! It may be that we all become more dextrous so we can type/use machines better for example.

      I cannot tell the future so I can’t really predict accurately how we will evolve!
