In the 2nd decamillennium BP, I take note of developments in Egypt, which include several successive cultures with various degrees of transition from hunting and gathering to settled agriculture. There were similar developments in Iran and Anatolia. From here on, I will be concentrating on developments of Egypt, although this was not necessarily the highest or most advanced civilization: It was rivaled by Mesopotamia. Mesopotamian peoples were more important anciently than the size of modern Iraq would indicate, so it will take some time before these are developed to their proper place in this period. There were also some settlements in India and in China and Japan. There are identified cultures in France. So far I have little information on Africa or the Americas. A new series of social developments, for which I used the term the agricultural revolution, began. During this period, peoples and cultures I identify as horticultural, with settled farming, began to appear. Whether agriculture was invented independently in several cultures about the same time or whether it was an idea that spread rapidly does not appear clear from the evidence now available.
For Western Civilization, I have completed a review of anthropology. For some time, I have been anticipating making connections to biographies. I have now reached the point where I can begin to do this.
