The origin of modern humans is a matter of debate. There are two different theories regarding the origin of modern humans or Homo sapiens. The first and primary theory states modern humans emerged in one place and from a single origin. This theory is known as the Recent African Origin Model. It suggests that modern humans are the product of speciation during the late Pleistocene in Africa. Homo sapiens eventually migrated out of Africa to Eurasia, and replaced all other human populations, without interbreeding. Some of the replaced populations are believe to be the Neanderthals and the Homo erectus. The second theory proposes that modern human evolution happened trough emigration, this is known as the multiregional evolution model. This …show more content…
A Neanderthal brain volume equals or exceeds modern human dimensions, ranging from about 1200-1750 ml, and thus was on the average about 100 ml larger than modern humans. At first, Neanderthals were pictures as more brutish creatures but investigations and fossil evidence helped create a more robust archaic human characteristics. They represent a significant piece in the puzzle of humanity. According to Erik Trinkaus, “Detailed comparisons of Neanderthal skeletal remains with those of modern humans have shown that there is nothing in Neanderthal anatomy that conclusively indicates locomotor, manipulative, intellectual, or linguistic abilities inferior to those of modern humans. Neanderthals have therefore been added to the same species of ourselves.” The split between the ancestors of modern humans and of Neanderthals occurred about 500,000 years ago. Neanderthals appeared in the fossil record approximately 400,000 years ago. The first fossil remains were found in Germany in 1856. Some Neanderthal fossils and other remains are in excellent condition, they provide good information on Neanderthal culture. In 1887, two complete skeletons were found in a cave near Spy in Belgium, and more from sites in France in 1887, 1908 and 1911. These and other finds showed that the Neanderthals had populated Europe widely from about 130,000 to 28,000 years ago after which they became extinct. Most of these fossils were
