A young man named Charles Lyell had different ideas .He wrote a book about them called Principles of Geology .The earth ,according to Lyell ,was not only thousands of years old ,it was millions of years old .As to（关于）the common belief that changes in the earth's surface happen suddenly because of a single earthquake or flood ,he said that this might happen once in a while ,but usually these changes took place very slowly .He believed that the surface of the earth had been changing from the beginning of time .The changes ,he said ,were caused by the long-term action of the winds and seas ,and by forces such as volcanoes breaking out under the earth's surface .Once in a great while he thought ,a mountain might appear for the first time after an earthquake .But usually mountains would rise slowly and steadily.? Professor Henslow was interested in Lyell's ideas ,but he did not actually believe them .Charles Darwin could not make up his mind about them .But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world.?

At Cambridge ,Charles Darwin studied just enough to pass the examination ,and received his college degree in 1831.During this time ,he had become more and more interested in geology .At the end of the school year ,he went to North Wales with one of his teachers to examine the rock formations（构成） and to search for fossils（化石）.Fossils are the remains of ancient living things .They are usually found fixed in rocks in the earth's crust（地壳）.Fossils may be of animals ,such as fish ,insects ,birds ,or humans .They may be of plants from tiny leaves to huge trees.? When a living creature dies ,it usually decays（腐烂）or is eaten by animals .However ,if it sinks into a riverbed or is quickly covered by the blowing sands of a desert storm ,the bones are kept up in the earth. Over many years the soft inner parts of a bone disappear ,leaving the inside hollow. Water containing mineral enters into the hollow. Slowly the mineral hardens and makes the bone hard and heavy,like stone.

What will man be like in the future—in 5000 or even 50, 000 years from now? We can only make guesses, 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.
Let us take an obvious example. Man, even five hundred years ago , was shorter than he is today. Now, on average,  men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’ s capacity(容量). As time goes on , however , we shall have to use our brains more and more,  and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. 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 likely that man’ s eyes will grow stronger.
On the other hand, we tend to 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 great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature 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 a human being, with thoughts and emotions similar to our own. …
