The revised dating and uncovering of new artifacts from an archaeological site in Australia’s Arnhem Land has prompted archaeologists to revise theories as to when the ancestors of present-day Aboriginies first settled in what we now call Australia, pushing that date back by 20,000 years to a point in time 65,000 years ago. This revised timeline also implies that modern humans may have begun the colonization of Asia much earlier than previously assumed.

Scientists have discovered a mini eco-system full of strange creatures in a remote territory of Australia. The ‘lost world’, as scientists are calling it, is believed to have remained undisturbed for millions of years.

The discovery was made by Dr. Conrad Hoskin, of James Cook University, and Dr. Tim Laman, from Harvard University, who led a four-day expedition to the Cape Melville area of Australia, a region that he had been aware of for a decade but had previously only viewed from above. Their destination was a remote place situated on top of a high plateau measuring 1.8miles (2.9km) by 1.8 miles, and forms part of a larger range of mountains which extends for about nine miles (14.4km) and is around 3 miles (4.8km) across.

The fires currently searing through the Australian bush between Lithgow and Bilpin could create an unusual cloud formation known as a ‘Fire Cloud’ or pyrocumulus, predict fire analysts. The unique weather phenomenon only forms when areas of intense heat, such as bush fires or volcanoes, meet with an unstable atmosphere.

As fires burn, the hot air generated rises in a huge column upwards, with the space underneath being filled by cooler air, a process producing a convection column. The hot-air columns created can be extremely large and can rise high into the atmosphere carrying a large amounts of water vapour – one of the main combustion products of fire.

When British convicts were sent to Australia in the 18th and 19th centuries, they found that the island nation was already populated, but no one could figure out where these people had come from. The land was so isolated that it seemed impossible that anyone could have traveled there in unsophisticated boats.

Now a lock of hair that was collected by a British anthropologist 100 years ago may hold the key to where the aborigines originally came from, as it’s tested for its DNA. DNA from the hair reveals that these ancient ancestors arrived in Australia around 50,000 years ago, and they somehow managed to keep the whole continent to themselves until the British convicts arrived many years later.
