c. 4000 BC: The Barrera-Mordán site in the Dominican Republic provides evidence of early stone-working complexes within the Greater Antilles.

c. 4000 BC: The Barrera-Mordán site in the Dominican Republic provides evidence of early stone-working complexes within the Greater Antilles. This site is significant for documenting the presence of “Lithic Age” groups who utilized flaked-stone technologies for survival. These inhabitants are distinct from later ceramic-producing groups, representing a specialized adaptation to the Caribbean’s diverse natural resources. The discovery of such sites pushed back the timeline of human arrival in the northern islands significantly. Understanding these early complexes is crucial for mapping the initial migration routes from the surrounding continental landmasses.
