Humans trace ancestry to Africa, world’s first DNA study confirms

The most detailed genetic study of Indigenous Australians confirms the group is the oldest continuous civilisation on the planet.

The civilisation dates back more than 50,000 years ago, according to a new paper that was published alongside two others in Nature.

The research claims that around 72,000 years ago, a group of migrants began the journey out of Africa that would ultimately shape the future of humanity.

This single wave of travellers gave rise to all non-African populations alive today.

The researchers found that the ‘overwhelming majority’ of non-African populations stem from a single migration from Africa 72,000 years ago.

Along with this, they found evidence that Aboriginal Australians are descended directly from the first people to inhabit Australia.

And, the Deoxy ribonucleic Acid (DNA)/genetic material revealed traces of DNA, which suggest modern humans interbred with an early human species that has not yet been characterized as they migrated through Asia.

The researchers also say there appears to be a mysterious dispersal that occurred in Australia roughly 4,000 years ago.

While these migrants shaped speech and thought, they experienced a ‘ghost-like’ disappearance.

In the first major genomic study of Aboriginal Australians, researchers have confirmed that along with European and Asian ancestral groups, Papuan and Australian genomes too can be traced back to this migration.

The new evidence supports the idea that there was just ‘one exit event’ – but once out of Africa, the Papuan and Aboriginal ancestors branched off early on, with some eventually reaching Australia, where they would remain isolated from the rest of the world for thousands of years.

In the study, published to the journal Nature, an international team of experts collaborated with elders and leaders from various Aboriginal Australian communities, along with numerous other organizations.

The researchers sequenced the genomes of 83 Aboriginal Australians and 25 Papuans from New Guinea, using DNA from saliva to reveal new insight on the origins of modern human populations.

    Good, but visit the Masseiana website and peruse the works of Gerald Massey to see how informed we are. His opus “Ancient Egypt, Light of the World” said and says it all, and is treasure worth keeping for posterity. Cheers!
