Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For not many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights(了解). It is impossible to know today just what our Stone Age ancestors knew about plants. But from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, dyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognize literally hundreds of plants and know many properties of each. To them botany, as such, has no name and is probab-ly not even recognized as a special branch of "knowledge" at all.
