Question 2
When and how was Australia settled?
A. Fossil evidence from Lake Mungo in New South Wales suggests that Australia was settled as early as 100,000 years ago by Melanesian settlers who crossed the exposed land bridges connecting the Pacific islands.
B. An interglacial period around 70,000 B.P. allowed the seafaring people of Tasmania to navigate to the Australian mainland.
C. A glacial period around 50,000 B.P. exposed a land bridge connecting Asia and Australia, making it possible for humans to cross over on foot.
D. Humans crossed the narrow straits separating Asia and the then-continent of Sahul (Australia, New Guinea, and Tasmania), perhaps in primitive watercraft, around 50,000 B.P.
E. Fossil evidence from Lake Mungo in New South Wales suggests that Australia was settled around 50,000 B.P. by humans following big game from Asia.
