of Africa, under the Out of Africa hypothesis, the first humans to leave Africa.8 million years ago divided into several different species during the Pleistocene. On the other side the Out of Africa theory is drastically different. Erectus became isolated and each followed a similar path of evolution until they developed into archaic humans. Once developed into. One of the most common questions is how to differentiate the Multiregional evolution hypothesis from the Out of Africa hypothesis.

The sides agree on two different theories called the Out of Africa theory and the Multiregional (or Candelabra) theory. The genetic backing of the Out of Africa Theory strongly supports the legitimacy of the theory, and provides evidence that it is a legitimate theory of how modern humans came to populate the earth. At the same time, modern humans from other parts of the world show some skeletal similarities and a small proportion of genetic similarities with earlier archaic human populations from those areas, including the Neanderthals. Migrated out of Africa through the north approximately one million years ago and spread throughout the rest of the world. After some time several populations. The theory is based on the idea that our modern human populations have a single source of ancestry and that we are all derived essay on sectionalism civil war significance from that source called Eve. Humans have low genetic variation today, and this variation is highest in Africa, and much lower in other parts of the world. However, this is counteracted by the idea that other species such as Neanderthals were simply not equipped for the environmental changes, and were killed off by natural selection (Thorne amp; Wolpoff, 2003,. The origin of modern humans in Africa explains why today's Africans are more genetically variable than other populations - they were the first human population to expand, and other populations (like those of Europe and Asia) were founded later. Under the Multiregional evolution hypothesis, the first humans to leave Africa.8 million years ago never divided into different species. This suggests that these lice were passed on from more archaic species to modern humans (Ember, Ember, amp; Peregrine, 2009,. These scientists have found overwhelming evidence of early human life across different continents, but are always working to attempt to explain what they have discovered, and try to piece together the earliest signs of human civilization.
