The history of education according to Dieter Lenzen, president of the Freie Universität Berlin 1994, "began either millions of years ago or at the end of 1770". Education as a science cannot be separated from the educational traditions that existed before. Adults trained the young of their society in the knowledge and skills they would need to master and eventually pass on. The evolution of culture, and human beings as a species depended on this practice of transmitting knowledge. In pre-literate societies this was achieved orally and through imitation. Story-telling continued from one generation to the next. Oral language developed into written symbols and letters. The depth and breadth of knowledge that could be preserved and passed soon increased exponentially. When cultures began to extend their knowledge beyond the basic skills of communicating, trading, gathering food, religious practices, etc., formal education, and schooling, eventually followed. Schooling in this sense was already in place in Egypt between 3000 and 500BC.
Nowadays some kind of education is compulsory to all people in most countries. Due to population growth and the proliferation of compulsory education, UNESCO has calculated that in the next 30 years more people will receive formal education than in all of human history thus far.[3
