if you have heard of people refering to "austronesian", they prefer that kind of people

"Austronesian" is way after all this. Basically, according to Spencer Wells (a leading expert at Stanford and Cambrige who specializes in tracing the Y-Chromosome/male lineage), all of the people in the world resembled Africans until around 30,000 years ago, when people reached farther north and when the Ice Age began to arrive. He's basing this on the archeological fossil record.
So, any migration before that is all by "African"-like people and before any of the modern ethnic groups have formed. I read somewhere that up until the Neolithic (around 5000 B. C. in East Asia), people in Southeast Asia and southern China were still African in skull characteristics.
Proto/Paleo-"Mongoloid" and "classical Mongoloid" characteristics developed in the north in successive processes. According to Wells based on Y-chrosome lineage analysis, these types later colonized Southeast Asia in successive waves starting from 10,000 years ago, when agriculture and animal husbandry were established in northern China and central China.
Both Wells and Cavalli-Sforza (two of the pioneers in using genetics to try to trace human origins and development) now concede that Southeast Asians are mainly a mixture, of various degrees, of "Mongoloids" and the orginal "Oceanians", who are sub-Saharan African in appearance and who kept the original look of humans because there was no need for adaptation.
Peking Man and Java Man (Homo Erectus) are not direct ancestors of any modern humans. They came out of Africa in an earlier wave and were largely displaced by Homo Sapiens who later came out of Africa. There could've been some admixture though but there is virtually no genetic evidence for it.
What I have written is mainly based on the latest consensus of geneticists, archeologists, and anthropologists. The
Journey of Man by Spencer Wells is designed to introduce this subject to those interested laymon. It is a good starting point to understand the key concepts and theories.
For anyone interested in this, I urge you not to speculate wildly or depend on internet sources. This subjective is very complicated and multi-faceted and even "experts" at Standford are constantly regrouping their thoughts. Get books or PDF documents from universities/researchers but learn the concepts and vocabulary first, or else you won't know how to interpret what you read, let alone understand it..
