Early Cultures
Main article: History of science in early cultures See also: Protoscience and AlchemyIn prehistoric times, advice and knowledge was passed from generation to generation in an oral tradition. For example, the domestication of maize for agriculture has been dated to about 9,000 years ago in southern Mexico, before the development of writing systems. Similarly, archaeological evidence indicates the development of astronomical knowledge in preliterate societies.
The development of writing enabled knowledge to be stored and communicated across generations with much greater fidelity. Combined with the development of agriculture, which allowed for a surplus of food, it became possible for early civilizations to develop, because more time could be devoted to tasks other than survival.
Many ancient civilizations collected astronomical information in a systematic manner through simple observation. Though they had no knowledge of the real physical structure of the planets and stars, many theoretical explanations were proposed. Basic facts about human physiology were known in some places, and alchemy was practiced in several civilizations. Considerable observation of macrobiotic flora and fauna was also performed.

Famous quotes containing the words early and/or cultures:
“The conviction that the best way to prepare children for a harsh, rapidly changing world is to introduce formal instruction at an early age is wrong. There is simply no evidence to support it, and considerable evidence against it. Starting children early academically has not worked in the past and is not working now.”
—David Elkind (20th century)
“Both cultures encourage innovation and experimentation, but are likely to reject the innovator if his innovation is not accepted by audiences. High culture experiments that are rejected by audiences in the creator’s lifetime may, however, become classics in another era, whereas popular culture experiments are forgotten if not immediately successful. Even so, in both cultures innovation is rare, although in high culture it is celebrated and in popular culture it is taken for granted.”
—Herbert J. Gans (b. 1927)
