Read this excerpt. Scientists relied on which two methods to solve the mystery of how ancient people reached the islands?
A the success of an explorer who sailed on a raft from South America to Polynesia
B news accounts of issues involving the Polynesian government and its laws
C DNA analysis of people on the islands compared to other people
D journal entries of people who disappeared from the island long ago
E measurements taken by research ships that study the tides in the area
The correct answer is C DNA analysis of people on the islands compared to other people.
Explanation: Scientists often use DNA analysis to trace the ancestry and migration patterns of populations. By comparing the genetic material of modern individuals on the islands with that of other groups, they can infer historical movements and connections. This method is crucial in understanding how ancient peoples may have reached distant lands.
