Step-by-step explanation:
The earliest archaeological evidence of humans in Australia is from Lake Mungo; dating to approximately 40,000 years before present (yBP). This discovery is significant because it indicates the presence of early humans on the Australian continent well before European colonization and provides insight into the migration patterns of ancient peoples. The Lake Mungo site is one of the key archaeological locations in Australia, where some of the oldest human remains have been found, including the well-known Lake Mungo 3 (LM3), also known as Mungo Man.
