Scientists can’t say for certain what the man of the future will look like. But they do predict that he will have a smaller face and a bigger nose. He’ll have less hair than he does now, in fact, he might even be bald!
Man’s face has been gradually getting smaller since cave-man days. In those days, man needed big teeth to tear at big hunks of meat. As his diet changed, his teeth became smaller. So did his jaws and his face. It is possible that the man of the future might very well be born without wisdom teeth, tonsils, and an appendix, which many doctors say serve no real functions now.
The average height of humans is increasing, our little toes are getting smaller and so are our ears. Maybe in 2000 years time mankind will be 8 feet tall with tiny faces, no ears, no hair and 8 toes. Then we can play basketball all day while robots do the work.
