What will man be like in the future — in 5,000 or even 50,000 years from now? We can only make a guess, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Now look at the chart below, and you’ll find some differences.
Body part | Changes | Reasons |
Height | Grow taller | About 3 inches taller than 500 years ago |
Head | Larger | Man uses brains more and more |
Eyes | Grow stronger | |
Arms and legs | Grow weaker | Used less |
Fingers | Grow more sensitive | Used a great deal in modern life |
Hair | Disappear | Does not serve a useful purpose any longer |
