Anthropology Has New Theory on Australian Aboriginals

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 f

An Efficient Hydrogen-Hybride Bike (Hy-Cycle) Developed

If you want to clean up the environment get a bike. Not just any bike though: you need a Hy-Cycle with pedal power assisted by hydrogen. A team of developers at the School of Chemical Engineering led by Associate Professor Kondo-Francois Aguey-Zinsou has put a lot of work into the new bicycle. The main problems in the past has been storage and cost. Hydrogen is now safely stored in hybride, a stable metal. This "compound" is then secured in a canister. Hydrogen is fed into a fuel cells that charges a lithium battery. The battery range is 125 kilometers at a cost of $2.00. This distance is sufficient for a day's use on one charge. Major cities across the world have already established bicycle pools where people can collect a bicycle, ride it to their destination and leave it at the nearest bike station. It would not be difficult to hire out the new powered Hy-Cycles at a small fee alongside ordinary bicycles. Improvements are already on the way. The current sto

Australian Birds Change Breeding Times to Suite the Harsh Climate

Human beings may be having problems with variable weather in Australia, but animals are coping well. Zebra finches, pelicans and woodswallows seem to know when the weather changes. If the Spring comes early they nest early. If it is too dry to breed they hold off until times are better. They change their breeding point by months either way. When glaciation was at its peak the woodswallow population actually boomed. In boom times there is a larger pool of gene carriers ideal for genetic selection when times become harder. More of the birds die off. Yet, the survivors have traits that suite the changed environment. Australia has the harshest of climates with long periods of drought. Consequently, birds such as pelicans live a longtime on a meagre diet so they can wait for good times to breed. Zebra finches seem to do well even when times are very hard. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml

Australian and Mediterranean Great White Shark Evolution

Luck plays a large part in evolution. Climate suddenly changes and if by chance a species of animal carries suitable genes to flourish in the new environment that animal lives on. Other species die off because they cannot cope. New findings about the great white shark highlights this. Australian great whites and the Mediterranean type have genes that point to common ancestry. It is believed that a few related female sharks split up. Some going north to the Mediterranean from the larger gene pool in the south, or they peeled off from the main group in the Atlantic some going north the others going south. Narrow channels in the Mediterranean stopped this group from rejoining the Australian gene pool. This happened 450,000 years ago. Mutations since that time make the timeline clear. It is believed that swordfish and tuna the main food of the great white also split off from the their main groups. Great white sharks followed the food supply. http://www.adventure--australia.blogspot.com

Fish Are Intelligent and Can Remember

For years scientists told us what we wanted to believe - that fish have short memories only lasting one lap of the fish bowl. Now the truth has got out. They are intelligent creatures who can learn to do things and can even deceive other animals. Once attacked, if they escape, they remember which predator tried to kill them. Unlike humans, however, there is a cost when they use their intelligence. If they are given one fish for food they are very efficient in catching it, but if given two types of prey they apparently become confused and their effectiveness declines. Fish interact in a social way. They recognize familiar others and modify their behavior accordingly. Siamese fighting fish will take advantage of a weak fighter by observing fish fights and readily attacking the weaker fish. Fish that clean others act busy when potential "customers' are watching. In a way they advertise. The myth about fish having no memory or even intelligence is most likely promulgated to ju
