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

Perhaps all this gives the impression that future man will not be a very attractive creature(生物) to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be human being, with thoughts and emotions(情感) similar to our owns.
