Based on the migrations of Homo sapiens, the most suitable events to replace the question marks in the table are:
arrive in Asia; arrive in Australia and Pacific islands
So the completed table would be:
- 200,000 years ago: appear in Africa
- 40,000 years ago: arrive in Europe
- 20,000–60,000 years ago: arrive in Asia
- 15,000 years ago: arrive in Australia and Pacific islands
Therefore, the correct response is:
arrive in Asia; arrive in Australia and Pacific islands
