Theories of Early Human Migration Routes.

There are two Major contending theories thus far for the early migration of modern man. The first is Out of Africa theory and the other is the Multiregional hypothesis, and both are scientific. I'll be addressing the latter.

Out of Africa" theory (OOA) is the most widely accepted model of the geographic origin and early migration of anatomically modern humans.[1] Although Chinese researchers argued that modern man were already living in China [2]

However,The major competing hypothesis to the OOA is the multiregional hypothesis, which envisions a wave of Homo sapiens migrating earlier from Africa and interbreeding with local Homo erectus populations in multiple regions of the globe. [3]

It is fascinating to realize that the multiregional hypothesis suggested that modern man was fully evolved and occupying regions of the world when the Ancestors of Africa came along and intermarry with them.
You may wonder where did these people came from in the first place.

The distribution of early migration routes indicate a single point of interconnection around the region of Mesopotamia (Area where Noah's Ark rested)[see figure 1] which may suggest a point of origin or dispersion for this migration. Furthermore, the Hypothesis propounded that the appearance of genetic variance (gene flow)[3] within the population of that given region, is indicative of a specific subset of race, which by inference we can suggest to what gave rise to the different races occupying these geographical region we see today, Asian, African, Caucasian, Australasian etc.[see figure 2]

Therefore, appearance of modern man at different location gives the possibility that man never evolved from ape at all, on the contrary, modern men had existed since the beginning.

This may sound far fetched but, hey its worth consideration.
Again its my opinion am no expert believe what you will.
