New Theory of Anthropology is Not Strong

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 stolen from rivals if a fire went out.

Mainland Aboriginals have genes different from other peoples. In Europeans, for example, females genes are much the same. The genes of Aboriginal mothers vary between geographical groups. This indicates that males moved while females stayed in the same location. However, divergence is the norm for humans. Unlike other apes who tend not to move at all and remain genetically "static".

Languages Falling in Number With Deforestation

Human societies change as the climate changes. Man is a clever animal. He uses his mind to overcome obstacles in nature. When we came down from the trees the first changes were made. This sped up our evolution to become more intelligent.

With evolutionary advancement certain things are lost. Tree clearing has led to an unforeseen event: languages are disappearing. Some, usually forest living, people speak more than a dozen languages. However, their tribes are decreasing in number as more contact with advanced societies and destruction of the environment they live in continues.

Papua New Guinea still has about 1,000 languages. Isolation is diminishing so more dialects are lost as times goes on. It has been said that as biodiversity falls so languages decrease in number. However, less biodiversity is an effect of less forestation rather than a causal factor.

Forest living people are moving to cities to find work as their livelihood disappears. Furthermore, governments find it easier to ignore minor languages and concentrate on teaching the one most used. Therefore, language are being lost at a much faster rate than wildlife and forests.

Asian Tiger Mosquitoes Moving To the Australian Mainland

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 Papua New Guinea. They came from Indonesia, so migration is normal for the insect.

Past Interaction of Indians With Australan Aboriginals Is Questionable

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 waves of movement out of Africa. Southeast Asia is much closer to Australia than India. When Europeans first arrived in Queensland there were two types of Aboriginals, One very dark skinned with robust features like natives of New Guinea, and a lighter skinned more gracile kind.

India is divided socially today into very dark skinned people who have been in the country for a large period of time, probably those left behind on the Aboriginal migration to Australia, and lighter skinned Indians who arrived more recently. There may not have been later interaction from those who remained in India on the very first journey from Africa and Australian Aboriginals..
