Evidence to contradict and challenge the African human origin migration hypothesis
It is a blatant lie – Brought forward to avoid division between races, nations or cultures.
1a) When war is the common historical repeating story, anything that could aggravate, justify and
increase divisions and separatism would seem bad, undesirable and should be avoided with any force, even a lie.
1b) When anthologists, palaeontologists and archaeologists, arrived at the doyen of
their [pre-DNA] knowledge they knew quite well that the migration hypothesis had some glaring big holes in it. DNA evidence has since shown [proved] that Humanity is comprised of a number  main sub-species. The pre-human world consisted of many sub-species
increasing the further back you look through the Pleistocene and some time after the beginning of the Pliocene. This evolutionary accepted fact stands to justify that that evolutionary process and the resultant genomes existed on into the emergence / evolution
of the larger brain sized sub-species we see on Earth today.
1c) We know, that before there was life on Earth there was life in the Seas of the world. Unlike the land there are no borders or obstacles
to separate species and divergent evolution. Successful species multiplied from their early genres and would have spread out to different watery regions to establish their niche regions and specialized for the varied environmental conditions and the differing
food sources available.
1d) Gondwana Land 400 MYA - There were no separate continents. When the transitional species climbed onto the land ‘it’ they did so everywhere
possible at once [in evolutionary terms]. The environmental and food differences of the preceding adapting evolution formed the basis of the differences that we see today in all regionally evolved sub-species. [Later, Orangutan's did not migrate from Africa
therefore this Great Ape evolved outside of 'the cradle of humanity' and therefore questions its validity and implicates humans and pre-humans in a wider area theory of development.]
would be perfectly reasonable under the terms of Darwinian evolution to presume that even during the Halocene humans broke into many sub-divisions of species bordering between the definitions of breed, familia, sister taxon and separate
species. [As with the Tiger.]
