植物學Botany
Botany
  Botany, the study of plants, occupies a particular 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.They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes.Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each.To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all.
  Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows.Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple.When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season—the first, great step in a new association of plants and humans was taken.Grains were discovered and from them flowed the wonder of agriculture: cultivated crops.From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away.

植物學
  植物學研究植物在人類知識史中占有特殊的地位。數千年來,人類只知道哪些人比任何人更有洞察力,這是一個領域。今天不可能知道什么是什么我們的石器時代的祖先知道植物,但從我們所看到的仍然存在的前工業社會,對植物及其特性的詳細了解必須是非常古老的。
  這是合乎邏輯的。植物是所有生物食物金字塔的基礎,甚至是其他植物。它們一直對人們的福利非常重要,不僅是食物,而且服裝,工具,藥品,住房和一個偉大的許多其他的目的。今天生活在亞馬遜叢林中的妓女認識了數百種植物,并了解了它們的許多特性。對他們來說,植物學沒有名字,可能根本不被認為是“知識”的特殊分支。
  不幸的是,我們變得越工業化,我們離植物的直接接觸就越遠,而我們的知識越不明顯。每個人都在不知不覺中植入了大量的植物知識,很少有人會認不出玫瑰或蘋果。當大約一萬年前居住在中東的新石器時代的祖先們發現,在下一個季節,某些草可以被收割,并且它們的種子被種植成更加豐富的田地,這是第一個在植物和人類新的關聯中邁出的第一步他們發現了一些水晶,并從中發現了農業的奇跡:種植的農作物。從那時起,人類將越來越多地從一些植物的控制生產中獲得生命,而不是在這里生長一點點,野生的,數萬年來與野生植物的經驗積累的知識將開始消失。
