How do you think humans will look like a thousand years from now??? and wat caused that change?

Humans live in artificial environments that act as adaptations themselves leaving no evolutionary pressures for humans to adapt to. Evolution is caused through mutations and is then continued by evolutionary pressures such as the leaves on a tall tree being to high up for certain giraffes with shorter necks and only the long neck giraffes survive because they are able to obtain food and reproduce. This happened over thousands of years and is why giraffes have long necks. With that said humans have long been trading adaptation and changing the land to adapt to us. We have houses to protect us from the elements, medicines to protect us from diseases, and machines to help us accomplish tasks. The example you give could be a possible adaptation only if we were exposed to the sun almost all of the time for thousands of years and lived outdoors.
