The two colors represent two models. The red lines show two major streams issuing out of Africa, a northern route which pushed into the heart of Central Asia, and a southern oceanic one, which pushed all the way into Australia. The second differs, with eastern and western branches of non-African humanity. The models really start to break down within the last ~10,000 years. For example, by either model India has seen an admixture even between the two branches in the Holocene. Additionally, there may have been &#8220;false dawns&#8221; and admixtures.<\/p>\n<p>In the early 2000s I accept the probable likelihood of the first model.
