The multiregional evolution model emphasizes regional origin and continuity in the evolution from Homo erectus to Homo sapiens and later anatomically to modern humans (Fitch , 1995 :204 . Based on an examination of the Peking Man numerous characteristics can be found similar in modern Asians which Weidenreich as the author of MRE postulated that human races have evolved independently in the Old World from Homo erectus to Homo sapiens sapiens , while at the same time there was gene flow between

the various populations and general adaptation flowed relatively rapidly from one part of the world to the other (Kramer , et al 2001 , 51 . In Templeton , the premise of multiregional evolution explains that human evolution during the Pleistocene is characterized by discreet dispersal events intercalated with recurrent gene flow with isolation by distance (Templeton , 2002 :46 . Judging from this compounded theory and in this scheme , human evolution from the beginning of the Pleistocene is characterized by one major evolving lineage

In effect , based on the study of human populations , MRE model explains that the regional features of East Asians and Australasian populations reflect certain continuity from Homo erectus to modern Chinese and Australian aborigines (Lahr , 1996 :189 .This category of multiregional evolution speaks on the nature of Homo erectus which truly represents the pandemic human specie as the direct progenitor of the Homo sapiens This specie has emerged in the east , in the saga of human evolution only to go extinct without issue when modern humans expanded their range out of Africa to encompass the far reaches of the Old World . While findings linked Australian aborigines to the modern Chinese and Indonesians through key skeletal and dental traits of people with inhabitants of Indonesia some 100 ,000 years ago (Thorne , 1989 : 16 geographical and geological events support the findings . Fauna in Indonesia in the Asian continent and Australasian continent have many similarities brought about a geographical link during the Permian period (Metcalfe , 2001 73 . As a result , animals from Eurasia mainland could travel to the archipelago that resulted to the formation of new species . This process continued until the regions were completely separated If dispersals started in Africa , a separate tropical-sub-tropical coastal route was via a Southern land bridge when sea levels were low (Lahr , 1996 : 190 . The Australasian continent is considered appropriate for prehistoric peoples due to its dense subtropical forests in the North . Borg suggested that European settlement at that time prove risky due to large masses of ice deposits further evidenced by prehistoric animal migration to the south (Borg , 2001 :188 Additionally , Europe 's large landmass enabled only the life forms that are able to adapt to a wide array of competitors . Human ancestors may not have been prepared to inhabit Europe immediately during the Pleistocene period which resulted to emergent proof of earlier human life forms in Australasia .MRE contends that all human populations of the past made differential contributions to all populations of the present and does not...
