The peopling of the Caribbean islands is a subject of ongoing archaeological and anthropological research. While the exact details continue to be refined, several prominent theories explain how Amerindian groups arrived in the region.
The most widely accepted theory posits that the first inhabitants migrated from the South American mainland, specifically from the Orinoco River delta in present-day Venezuela. Beginning around 3000–2500 BC, these early settlers traveled in canoes and other small watercraft, island-hopping northward through the Lesser Antilles and eventually reaching the Greater Antilles. This migration is associated with the Ortoiroid and later Saladoid cultural traditions.
Another hypothesis suggests that some groups may have reached the Caribbean from the north, particularly the Gulf Coast region of North America. These movements could have occurred both by sea and via land bridges that existed during periods of lower sea levels. Evidence for this route is less extensive but remains a topic of study.
A more controversial proposal argues for direct long-distance oceanic voyages from regions as far away as West Africa or Southeast Asia. Proponents point to alleged similarities in pottery styles and other cultural artifacts. However, mainstream scholarship regards the evidence as inconclusive, and the extent of such voyages—if they occurred—remains heavily debated.
Current consensus favors a model of multiple migration events over several millennia. Different groups arrived at different times from various source areas, primarily South America, with possible minor contributions from North America. This layered settlement created the diverse cultural landscape encountered by Europeans in 1492.
