For the millions of people around the world who live on islands today, a plane or boat can easily enough carry them to the mainland or other islands.
But how did people in the ancient past first make it to distant islands they couldn’t even see from home? Many islands around the world can be reached only by traveling hundreds or even thousands of miles across open water, yet nearly all islands that people live on were settled by between 800 to 1,000 years ago.
Archaeologists like us want to understand why people would risk their lives to reach these far-off places, what kinds of boat and navigational methods they used, and what other technologies they invented to make it. Islands are important places to study because they hold clues about human endurance and survival in different kinds of environments.
One of the most interesting places to study these processes is the Caribbean, the only region of the Americas where people settled an archipelago with some islands not visible from surrounding areas. Despite more than a century of research, there are still many questions about the origins of the first Caribbean people, when they migrated and what routes they took. My colleagues and I recently reanalyzed archaeological data collected over 60 years to answer these fundamental questions
