and cook food. Skulls were found in Java of Homo erectus that dated to about 300,000 years ago. A skull was found in Central China that was similar to the Homo heidelbergensis remains that were found in Europe and Africa and are dated between 200,000 and 50,000 years ago. Homo sapiens Between 60,000 and 100,000 years ago, Homo sapiens came to Southeast Asia and Australia by migrating from Africa, known as the "Out of Africa" model. Homo sapiens are believed to have migrated through the Middle East on their way out of Africa about 100,000 years ago. Near Nazareth, remains of skeletons, including a double grave of a mother and child, dating to about 93,000 years ago were found in a Jebel Qafzeh cave. Included among the remains was a skeleton of another species which was not Homo sapiens; it had a "distinct and undivided browridge that is continuous across the eye sockets" and other discrepancies. Researchers believe that the modern human, or Homo sapiens, migrated about 60,000 years ago to South Asia along the Indian Ocean, because people living in the most isolated areas of the Indian Ocean have the oldest non-African DNA markers. Humans migrated into inland Asia, likely by following herds of bison and mammoth and arrived in southern Siberia by about 43,000 years ago and some people moved south or east from there. By about 40,000 years ago Homo sapiens made it to Malaysia, where a skull was found on Borneo in Niah Cave. Homo sapiens females weighed an average of and were on average tall. The males weighed an average of and were on average tall. They were omnivorous. As compared to earlier hominids, Homo sapiens had larger brains and used more complex tools, including, blades, awls, and microliths out of antlers, bones and ivory. They were the only hominids to develop language, make clothes, create shelters, and store food underground for preservation. In addition, language was formed, rituals were created, and art was made. Prehistory by region North Asia Above China is North Asia, in which Siberia, and Russian Far East are extensive geographical regions which has been part of Russia since the seventeenth century. At the southwestern edge of North Asia is Caucasus. It is a region at the border of Europe and Asia, situated between the Black and the Caspian seas. Caucasus is home to the Caucasus Mountains, which contain Europe's highest
