182. The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years ago. Recently, however, 4,500-year-old stone agricultural implements were unearthed at Colha. These implements resemble Mayan stone implements of a much later period, also found at Colha. Moreover, the implement's designs are strikingly different from the designs of stone implements produced by other cultures known to have inhabited the area in prehistoric times. Therefore, there were surely Mayan settlements in Colha 4,500 years ago.

Answer: Successor cultures at a given site often adopt the style of agricultural implements used by eariler inhabitants of the same site.
