Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights. 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.
选项
答案
植物学,研究植物的学问,在人类的知识史上占有特殊地位。几千年来,人类对于许多领域的知识仅有非常模糊的了解,只有植物学,人类对其了解还比较深入。今天我们无法知道石器时代的祖先们对植物究竟了解多少,但是从我们观察现存的前工业化社会得到的结果来看,对植物及其性质的详细研究肯定很早就开始了。这是合乎逻辑的。植物是所有生物,甚至包括其他植物的食物金字塔的基础。
