I accept the fact there were ancient Blacks in EurAsia. These Blacks were the Australian type people who mainly live in Australia and the Hill regions of Oceania.
The coastal Melanesians on the otherhand, are descendants of recent Africans who settled the area after being forced from Asia. The Polynesians/Filipinos and etc., who are known as the [b]original Mongoloid people and called Classical Mongoloid [/b] in the literature probably originated in Anatolia or Mesopotamia.
The Australians are the original settlers of Asia (around 60kybp), and may represent members of the first out of Africa migrants. I never refer to these people as Africans, although I do recognize them as Blacks.
The Bushmen/ Khoisan probably represent the second African migration of homo sapien sapiens out of Africa. I would class these people with the CroMagnon/Grimaldi group who entered Iberia after 34kybp. Remnants of this great people were found on every continent when Europeans first explored the world.
The Anu or Black pygmies (/Proto-Bantu) type may represent the Natufians who began to migrate out of Africa after 20,000 and settled in the Levant which was first settled by Cro Magnon people who early replaced the Neanderthal folk. The Natufians would represent the fourth African migration into Eurasia.
By the time the Anu entered Eurasia the Classical mongoloid people who are the ancestors of the Indonesians/Vietnamese/Filipinos and etc. were probably already settled in Anatolia. The classical mongoloids probably constructed Catal Huyuk.
The close relationship between Sumerian and the AustroAsiatic languages suggest that the classical Mongoloid people may have also inhabited Mesopotamia by the time the Sumerians entered the area.
It appears to have been a natural catastrophe which caused the classical mongoloids to migrate eastward. We know this because many of the former sites of the Classical mongoloids in Anatolia were occupied by the Kushites (Kaska) people after 2500 BC.
By 1200 BC the clasical mongoloids had become well established in India. Around this time they conquered the Dravidian people who founded the first Shang empire, and set up a new Shang Empire at Anyang.
By 1000 BC the Hau/Han tribes came down from the mountains and pushed the classical mongoloids southward into Yunnan and eventually Southeast Asia. The Han began to make the Yueh and li min people their slaves. The Han often used the Qiang (another Black tribe) as sacrifice victims.
The Han killed off as many Black tribes as they could. The only thing that saved the pygmies in East Asia, was the fact that they moved into the mountains in areas they could easily defend from Han attacks.
This movement of Han and classical mongoloid people southward forced the Kushite/African (Qiang, li min and other African) tribes onto the Pacific Islands. It is these Africans who represent the coastal Melanesians.
The Sumerians, Elamites, Xia (of China), Harappans of the Indus Valley and coastal Melanoids are the Proto-Saharan people known in History as the Kushites.These people originated in the Highland regions of Middle Africa, and began to occupy the former trade centers of the Anu in Eurasia and the Americas. It is for this reason that we find West African placenames in the Pacific and India.
Given the origin of the classical mongoloids in Anatolia, and the Han Chinese somewhere in North China or Central Asia,the Southeast Asians are not descendants of the first African migration to Eurasia. This is why the Chinese and Classical mongoloid people share few if any genes with the Australians. The Classical mongoloids share genes mainly with the coastal Melanesians who are of African origin, but few genes with the Chinese of East Asia.
