Geneticists who deem the permutation hypothesis argue that the similarities shared by all of the modern human populations confirm the existence of a common gene pool, and perhaps even superstar common distaff ancestor. They point to the fact that many modern human traits shake evolved within the past 200,000 long time as turn up of the replacement hypothesis. Furthermore, they cite studies of DNA in cell structures called mitochondria, which codes most of the ancestral traits from ancestors. Most of these studies demonstrate that the diversity among human populations is very beautiful as compared with other species. They conclude that there was only one small population from which all other populations descended.
From their point of view, the evidence supports the theory that modern humans migrated from a relatively small area in Africa almost 150,000 years ago, moving along a route through the Middle East 100,000 years ago, and slowly populating regions throughout the world by displacing the communities of less develop humanlike species that they encountered.
Paleoanthropologists concede that, to date, the oldest fossil remains of modern military man sapiens have been found in Africa, with the next oldest dicovered in the Middle East. European fossils are dated at close 50,000 years after the African fossils. Thus, it would appear that the replacement hypothesis is substantiared by archaeological evidence.

Okay, today I want to trounce about a hypothesis that explains where humans might have evolved and how they might have migrated around the world. Its an alternative hypothesis to the replacement hypothesis that you read about earlier. Its called the...If you want to get a full essay, order it on our website: Ordercustompaper.com
