D. 60,000; 40,000

Answer 1

Modern humans dispersed to Australia approximately 45,000 years BP and to North America and South America approximately 15,000 years BP.

Step-by-step explanation:

Modern humans dispersed to Australia by approximately 45,000 years Before Present (BP) and to North America and South America by approximately 15,000 years BP.

According to archaeological evidence, human settlements in places like Papua New Guinea and Australia date back to at least 45,000 years ago. However, the exact timing of when humans arrived in the Americas is still debated among archaeologists. Some theories suggest that humans arrived in the Americas around 16,000 to 13,000 years ago, while others propose earlier dates.

The Bering Land Bridge played a crucial role in the migration of humans from Asia to North America. Around 15,000 years ago, groups in Asia crossed into North America, eventually reaching the tip of South America and settling at various locations in between.
