c. 1000 BC: During the latter part of the Archaic Age, there is evidence that exchange networks intensified between the Caribbean islands and the Isthmo-Colombian region of Central and South America. These interactions involved the movement of goods, people, and ideas, which likely served as “lifelines” to parent communities on the mainland. This period of increasing connectivity laid the social and economic groundwork for the more complex sedentary communities that would emerge later. The variable material expressions observed across the Antilles during this time reflect local accommodations to diverse environments. These regional exchanges were critical for maintaining social cohesion and cultural identity among scattered island populations.
