D
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 because man is slowly changing all the time.
Let us take an example. Man, even 500 years ago, was shorter than he is today. Now, on average (平均), man is about three inches taller. 500 years is a relatively (相对地) short period of time, so we may suppose that man will continue to grow taller.
Again, in the modern world we use our brains a lot. Even so, we still make use of only about 20% of the brain's capacity (容量). As time goes on, however, we will have to use our brains more and more, and finally we will need larger ones! It is likely to bring about a physical change, too. The head, especially the forehead (前额), will grow larger.
Nowadays our eyes are being used too much. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time, it is possible that man's eyes will grow stronger.
On the other hand, we make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive (敏感的) because they are used a lot in modern life.
But what about hair? This will probably disappear from the body altogether as time goes on because it does not serve a useful purpose any longer. In the future, then, both men and women are likely to be hairless!
Perhaps all these give the idea that future man will not be a very attractive person to look at. This may be true. All the same (尽管如此), future man will still have a lot in common with us. He will still be a human being, with thoughts and feelings similar to our own.
