The Fascinating Genomic Study of Aboriginal Australians

🌍Aboriginal Australians are one of the oldest living human populations on Earth, leaving Africa around 70,000 years ago.

🔍The genomic study shows that Aboriginal Australians have a remarkable genetic diversity, with different populations being as genetically different from each other as Europeans and Asians.

🌏Aboriginal Australians took off early after leaving Africa, reaching the Australian continent when it was physically connected to Papua New Guinea.

🗺️Around 4,000 to 6,000 years ago, a cultural and linguistic change occurred in Australia, with the spread of the Pama-Nyungan-speaking family across the continent.

🧬The genetic signature of the population expansion around 4,000 to 6,000 years ago remains a mystery, but it had a significant cultural and linguistic impact on the indigenous population.
