10000 B.C.
10,500 years ago (8,500 BC): Earliest supposed date for the domestication of cattle.
10,000 years ago (8,000 BC): The Quaternary extinction event, which has been ongoing since the mid-Pleistocene, concludes. Many of the ice age megafauna go extinct, including the megatherium, woolly rhinoceros, Irish elk, cave bear, cave lion, and the last of the sabre-toothed cats. The mammoth goes extinct in Eurasia and North America, but is preserved in small island populations until ~1650 BC.
10,800–9,000 years ago: Byblos appears to have been settled during the PPNB period, approximately 8800 to 7000 BC. Neolithic remains of some buildings can be observed at the site.[33][34]
10,000–8,000 years ago (8000 BC to 6000 BC): The post-glacial sea level rise decelerates, slowing the submersion of landmasses that had taken place over the previous 10,000 years.
10,000–9,000 years ago (8000 BC to 7000 BC): In northern Mesopotamia, now northern Iraq, cultivation of barley and wheat begins. At first they are used for beer, gruel, and soup, eventually for bread.[35] In early agriculture at this time, the planting stick is used, but it is replaced by a primitive plow in subsequent centuries.[36] Around this time, a round stone tower, now preserved to about 8.5 meters high and 8.5 meters in diameter is built in Jericho.[37]
10,000–5,000 years ago (8,000–3,000 BC) Identical ancestors point: sometime in this period lived the latest subgroup of human population consisting of those that were all common ancestors of all present day humans, the rest having no present day descendants
