New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory.  But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stol...

With climate change insects move geographically. New regions open up to be populated. Warming of the Australian mainland has taken place. The Asian tiger mosquito has been found on Thursday and Horn islands in the Torres strait close to Australia itself. Dengue and chicungunya are the greatest dangers. These diseases can be fatal. There is no way the mosquitoes can be stopped. They will move into Australia proper. Spraying insecticides will only slow them down. They won't fly to Australia. They will be brought here on small boats moving all over the Torres Strait. The threat is serious. Once established in Australia Asian tiger mosquitoes will be spread by humans as far south as Tasmania. They prefer a cooler climate than the main dengue host, Aedes aegypti. Tigers will carry dengue, however. The outside-life of Australians is under threat. Having a barbecue will be a dangerous pastime. Recently it has been established that mosquitoes are not native to Pa...

Australia's physical connection with the mainland of Asia disappeared 4,000 years ago. It is assumed that people from India crossed into Australia before this time. There is little proof of this. Indians and Australian Aboriginals are distinctly different. Aboriginals are more like Africans, while Indians appear to be black Caucasians. DNA tests on both gene pools do show a link. However, this link could be directly from Africa 70,000 years ago. A similar thing could be said about Neanderthal genes being carried by some modern humans. The markers could have been there before both species split off from a common ancestor. The fact that Neanderthals have a different number of chromosomes is dismissed by some scientists when it is known that offspring of related species with differing chromosomes can have offspring but they are invariably "mules" who have infertile young. Australian Aboriginals are the earliest of Mankind to leave Africa. There were many wa...
