[Up: science] [Robot Wisdom home page]
This page is intended as a startingpoint towards a unified Web timeline of human history, as discussed here: [Timeline Project] [thread] more
To start as simply as possible, the first category I want to add is migrations, followed by population fluctuations and conquest.
Migrations info: [maps] [table] theory; [EB], NYT; USNews; newsbits
Population info: theory; maps; ancient
Eventually I want to add the 'things' (eg tools) that different cultures use. [GooJa thread] And their ethical systems. {GooJa post]
African climate: [timeline]
"From around 150,000 to 130,000 years ago, Africa experienced colder and more arid than present conditions. About 130,000 years ago, a warm phase moister than the present began, and this lasted until about 115,000 years ago, with greater rainforest extent and the deserts almost completely covered with vegetation. Subsequent cooling and drying of the climate led to a cold, arid maximum about 70,000 years ago, followed by a slight moderation of climate and then a second aridity maximum around 22,000-13,000 14C years ago. Conditions then quickly became warmer and moister, though with an interruption by aridity around 11,000 14C years ago. A resumption of warm, moist conditions led up to the Holocene 'optimum' [8000-6000 BC] of greater rainforest extent and vegetation covering the Sahara. Conditions then became somewhat more arid and similar to the present. Relatively brief arid phases (e.g. 8,200 14C y.a.) appear to punctuate the generally moister early and mid Holocene conditions."
