ANTH 1131 Lecture Notes - Wallace Line, Homo Floresiensis
Document Summary
Homo moved out of africa by 1. 8 million years ago and arrived in asia by 1. 6 million years ago (and reached java in approximately 1. 4 million years ago). There was still a substantial amount of water to cross from mainland. Although today java is an island, during cold periods such as the ice. Age, there were huge glaciers and mountain chains growing that would lead to the sea level dropping around the world. As a result, coastlines would change dramatically and islands would disappear and connect to mainland asia. During cold periods, you could walk to what are islands today. There have been dozens of ice ages over the million years, so there would be ample time for the homo erectus to walk to java. People (modern humans) are in australia at least by 40 thousand years ago: To get to australia, you would have to cross a vast amount of water, much more than to get to java.
