    The British send undesirables to be civilised by aborigenen
    "That great genetic diversity in Aboriginal populations reflects the huge amount of time they have occupied the continent," says co-author and senior research fellow Dr. Michael Westaway.

    Co-author and Dauwa Kau'bvai woman Colleen Wall toldABC she was pleased that both women and leaders of Aboriginal nations were players in the study, and that science seemingly verifies the multitude of Songlines, or sacred creation stories, that constitute the religious beliefs of Australia's First Nations.

    "As a society we already believe that we are the oldest race on Earth, and from my point of view this research goes some way towards proving that," said Wall.

    The Native Australians are the descendants of the first humans who successfully migrated out of Africa and established a viable new human colony. This occurred about 60KYA, during an ice age when food was scarce in Africa (and most of the rest of the planet, for that matter). For reasons that are difficult to determine so many millennia later, Australia had a balmy climate at this time, and the new immigrants surely felt like they had arrived in heaven.

    Nonetheless, Homo sapiens had been living successfully in Africa for tens of thousands of years before anyone:
    • 1. Felt the need to find another place to live.
    • 2. Developed the technology needed for a successful emigration.
    • 3. Were fortunate enough to survive a journey of many thousands of miles through unfamiliar terrain.
    • 4. Were able to find edible plants and animals, many of which did not resemble the edible plants and animals back home.
    Fortunately, the ice age itself was a big help. With so much of the planet's water frozen into the polar ice caps and the glaciers at the top of the world's tallest mountains, sea level was considerably lower, so all of the oceans and lakes were considerably smaller than they are today. This made it easier to sail across the Red Sea to Asia, and then to make the various crossings between the various islands in Polynesia--which, with more land mass, were much closer to each other than they are today.

    Still, it's unlikely that no Africans had ever thought of crossing the Red Sea before. It was standing there as a challenge, year after year, century after century, and our species loves a challenge.

    At this point, anthropology comes into play. Around 70,000 years ago, abundant evidence suddenly appears of complex, coordinated activities that could not have been performed by people who, at the same time, were using their hands for communication. This was the dawn of spoken language! With both hands free, humans can accomplish much greater feats. And indeed, 10,000 years later, when language had evolved into a sophisticated tool, the descendants of these humans made the first successful journey out of Africa.

    DNA shows us that the ancestors of the Native Australians were the San, who until recently were called "Bushmen." 60,000 years ago, their ancestors lived in the northern region of Africa, relatively close to the Red Sea. (The desertification of the Sahara about 10,000 years ago forced all of the African tribes to move south, where there was rain and food. The San now live in southwestern Africa, far from the Red Sea.)
    That's a little oversimplified. Other bands of humans emigrated out of Africa and established communities in Asia, and eventually on the Polynesian islands, not to mention the southeastern region of Asia itself.

    We have considerable evidence of this. One of the most important bits of evidence is the dingos, the wild dogs who roam Australia. Their DNA makes it clear that they were brought down by explorers from Asia. They're not ancestral wolves, yet they are also not modern, domesticated dogs. Dogs had not yet been domesticated when the San left Africa, so they were not companions on that first journey. Somebody brought those dogs down from Asia, and whoever it was... uh... "socialized "with the Australians--mingling their DNA with the original San DNA.
    Balderdash! Modern Homo sapiens have been living in Africa for more than 100,000 years. The Native Australians have been living in Australia for less than half that time.
