The oldest civilization existing today. They were the first explorers who dared to cross the ocean 58,000 years ago

After some extensive genetic studies proved that Aboriginal Australians are the oldest civilization still exists. Australian Aborigines are the first people who settled in Australia 50,000 years ago.

The three studies, published in the journal Nature, reveal information about the origins of historical migrations of mankind.



According to the DNA results, most modern eurasists are descendants of a single wave of migrants who left Africa about 72,000 years ago. During migration, Aboriginal Australians and Papuans (ancestors of the inhabitants of Papua New Guinea) were divided into two groups and were the first people who crossed the ocean 58,000 years ago, before he gets to Australia 50,000 years ago.

,, This story lacked science, '' said researcher Eske Willerslev of the University of Copenhagen, Denmark. ,, Now we know the ancestors of the Australians were the first explorers, '' he added.



Australian and Papuan native population was divided by 37,000 years before the continental masses to separate. Australian Aborigines remained isolated until nearly 4,000 years ago, but the journey of thousands of years they have been in contact with other species homini because about 4% of their genome belongs to an unidentified species of hominids.

In reaching this conclusion, the international team of researchers has sequenced the genomes of 25 Papuan and 83 Australian Aboriginal group in which language is used pama-nyungan, which is spoken by 90% of Australian aboriginal.

In a substudy led the Medical School at Harvard, was drawn a map of the genome originated from 300 people from 142 different populations around the world, through which they tried to discover genetic changes associated with the development features modern man caves such as painting, sculpting utensils sophisticated, but was not discovered any resemblance.

,, There is no evidence of a specific mutations that turned us into people, '' said Willerslev.

Although the two studies was suggested that there was a single wave of migration from Africa, the third paper provides evidence of the two waves of migrations from Africa.

Led by Luca Pagani, biologist and anthropologist from Tartu Estonian Biocentre in the study were discovered evidence of a huge migration 75,000 years ago, but the researcher has found evidence of a migration previous 120,000 years ago.

  Hello,

    I'm working on a theory for some time in trying to combine science with religion, looking for an answer to the question 
"What is the purpose of life in Creation?  Is it possible for life to be an unintended consequence of our Universe?

Finally due to space,science and exploration throughout the Universe we got everyone to agree with the fact that we are not the only planet with life.  My blog is full of interesting articles about Creation of the Universe with all his laws,  NASA's Missions,  History,   Science,  Physics, Health, Nature, Ancient origins and Culture.
