Archeologists Discover Ancient Supercontinent Sahul, Linked Asia to Australia

Archaeologists have uncovered evidence of Sahul, a lost supercontinent that facilitated human migration from Asia to Australia about 70,000 years ago. This finding hints towards the likelihood of many yet-undiscovered historic sites across the globe.

What is Sahul?

Sahul was a supercontinent exposed during the last ice age due to glaciation, which lowered global sea levels. This landmass connected present-day Australia with Papua New Guinea to the north and Tasmania to the south.

Discovery of Sahul

Researchers employed data analysis and reverse engineering of geological and environmental conditions to simulate Sahul’s landscape between 75,000 and 35,000 years ago. The simulation revealed two potential migration routes and numerous archaeological sites, indicating ancient human movement across this landscape in search of resources.

Significance

The discovery of Sahul provides insights into ancient human migration patterns and highlights the rapid adaptation of humans to diverse and adverse environments. This breakthrough could pave the way for uncovering more historical mysteries.
