Abstract
Computer simulations are used to shed light on the probable origins of the earliest Preceramic cultures of the Greater Antilles and to understand the navigation skills necessary for island colonization. These cultures, dating to between ca. 4000 B.C. and 2000 B.C., are found on Cuba, Hispaniola, and possibly Puerto Rico. Two areas, northern South America and northern Central America, have assemblages that bear resemblance to the assemblages of the Greater Antilles, but there are important differences. Chance discovery of the Greater Antilles is possible from three areas: northern South America, northern Central America, and southern Florida. Directed voyages have a high degree of success from all three areas. However, voyages from northern South America require the least navigational skill, making it the most likely source of colonization. From northern Central America, foreknowledge of the islands appears to be required, while directed voyages from southern Florida encounter considerable risk.
