Genetics: Australian Aboriginal stone tools use was made within the Aboriginal gene pool. Australian Aborigines have been isolated on this vast continent for 50,000 until Europeans came and messed everything up. DNA sequencing shows Aboriginals were pure for this whole period. Contrary to the view held by many scientists for centuries, people did not arrive from India 4,000 years ago. Seafarers from India and Southeast Asia did stop here to get fresh water and herbs to treat constipation. Yes, this is true. Data tracing the Y chromosome from father to son shows no Asian genes in their profile. Aboriginals were the first people out of Africa. Once they reached Australia no more came from Asia. The out of Africa theory has now been pushed back 200,000 years. There is no real evidence of where these people went as far back as that. Tasmanian Aboriginals are a mystery. All have now died out so we will never know if they came here before mainland Aboriginals. Their DNA cou

We have heard so much about how scientists are going to clone a mammoth. For many this idea remains "pie in the sky" - a lot of talk and no action. There is plenty of mammoth raw material around to do tests on. The problem is getting good DNA that can be cloned. Scientists are jumping up and down again with the recent find of a frozen mammoth in Siberia. They say this time their will be "living cells". This is very optimistic. The new mammoth will probably be like all the others. Only partial DNA will be found. Even though bone marrow has been identified this time, cloning is a long shot. No living cells have so far been found in any extinct animal, as far back as 10,000 years when mammoths roamed the Earth. There are problems in analyzing human DNA even though the human genome is known. The complete DNA of mammoths has not yet been determined. A prize is offered by the X Prize Foundation for the first cloned extinct animal. Scientists can hope I s
