Question:

Best Answer - Chosen by Asker:

The pre-Columbian inhabitants of Guanacaste are noted for the fine quality pottery that they produced.

The variety of ceramic vessels found at archeological sites has led investigators to theorize the existence of a well-developed system of agriculture, and specifically grain production.
The fact that as yet no evidence of hunter-gather societies has been unearthed in the region, has been a motive for speculating that the first humans to settle here already possessed a working knowledge of agriculture.
