The 9th millennium BC marks the beginning of the Neolithic period. Agriculture spreads throughout the Fertile Crescent and use of pottery becomes more widespread. Larger settlements like Jericho arise along salt and flint trade routes. Northern Eurasia is resettled as the glaciers of the last glacial maximum retreat. World population is at a few million people, likely below 5 million.
