Hundreds of thousands of artifacts dating back as early as 15,000 years have been found at the ancient mound site of Huaca Prieta in Peru. The relics include elaborate hand-woven baskets and tools for deep-sea fishing, which would have necessitated the use of boats that could withstand rough waters, as well as evidence of large-scaled agricultural production and trade. The findings indicate that an early civilization existed in the region which was much more advanced than originally thought.
