The 10th millennium BC marks the beginning of the Mesolithic and Epipaleolithic period, which is the first part of the Holocene epoch. Agriculture, based on the cultivation of primitive forms of millet and rice, occurred in Southwest Asia. Although agriculture was being developed in the Fertile Crescent, it would not be widely practised for another 2,000 years.[citation needed]
The world population is estimated as between one and ten million people, most of whom were hunter-gatherer communities scattered over all continents except Antarctica and Zealandia. The Würm glaciation ended, and the beginning interglacial, which endures to this day, allowed the re-settlement of northern regions. The most recent glacial ended c. 10,000 BC, and the world entered a period of global warming.
The Wal-Mart camel is the fossil of a prehistoric camel (Camelops sp.) found at a Wal-Mart construction site in Mesa, Arizona in 2007. Workers digging a hole for an ornamental citrus tree found the bones of two (juvenile and infant) animals that may have lived as long as 10,000 years ago. Arizona State University Geology Museum curator Brad Archer calls it an important and rare find for the area.Wal-Mart officials and Greenfield Citrus Nursery owner John Babiarz whose crew discovered the remains agreed that the bones will go directly to the Geology Museum at Arizona State University where further research and restoration of the fossils could be done. Camels lived in what is now Arizona until about 8,000 years ago.More camel bones were found in Gilbert, Arizona in May 2008.
