Mind-Boggling Discovery in Australia, 'The Land 'Down Under' --"Could Forever Alter the Timeline of Human Migration"
As the "Land Down Under," Australia is an island continent, so ancient visitors would have to arrived by sea, a long way from where humans first evolved in Africa. Migration to Australia would have required some remarkable ingenuity. Archaeologists have uncovered new evidence that could push the date of human habitation in Australia possibly as far as 80,000 years ago. The findings, that involve ancient tools and artifacts unearthed from Kakadu National Park in Australia's Northern Territory, suggest people crossed over from south Asia at a time that was cooler and wetter, with lower sea levels allowing easier sea crossings.
