The birthplace of Mankind is believed to be the Rift Valley in East Africa. It was thought that the valley formed over a long period of time. James Cook University scientists in Australia have found that a tectonic event changed the flow of the Congo, Nile and other rivers thus creating the Ethiopian-Kenyan eastern segment, and the Ugandan-Malawi western branch. Formerly the assumption was that this didn't happen at the same time. The eastern section developed up to 25 million years before the western segment. This was the prevailing theory. The Australian evidence indicates that the tectonic event created the eastern and western branches at much the same time. Climate change models will now have to be reviewed. Because the region is rich in fossils ongoing investigation occurs there. It is the only late Oligocene terrestrial fossil deposit in Africa below the equator. Though fossils of early Man have been found there, it may not be the actual birthplace of Mankind. I...

Elephants aren't so different from woolly mammoths. DNA samples taken from mammoth hair shows they are much alike. Furthermore, there are indications that the mammoth population was so low toward the end that inbreeding took place. If the unique mammoth genome can be isolated it can be inserted into elephant DNA to produce a woolly mammoth. It has also been found that differentiation between mammoth was only minor, so that a disease could have easily wiped them out. Mammoth are more closely related to elephants than chimpanzees are to humans, which is about 99 percent. Evidence shows that there were two groups of mammoth. One group died out 45,000 years ago, the other 10,000 years ago. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .

The argument continues over whether humans were responsible for the extinction of megafauna. Giant emus, large kangaroos, marsupial lions and diprodons were destroyed by Aboriginals in Australia according to new research. This claim is based on fungi in dung of herbivores. For 130,00 years, despite dry periods, charcoal and pollen levels in dung remained the same until Aboriginals arrived. This means that climate change was not responsible for the extinction of megafauna 40,000 years ago. There is a problem with this. When Captain Cook arrived in Australia the Aboriginal population was extremely low. Forty thousand years ago there would have been only a few hundred thousand of them. How could this low number possibly destroy all of the large animals? Some megafauna would have survived in regions where Aboriginals did not go. Australia is a very large continent. It is claimed that when the megafauna died out the vegetation changed with more fires, and eucalyptus forests spr...
