Pre-Clovis sites like Monte Verde and White Sands vindicate Leakey's early human timeline. In 1977, Monte Verde in southern Chile revealed wooden structures preserved in peat, stone tools, and butchered megafauna remains Monte Verde broke the Clovis first paradigm overnight White Sands in New Mexico revealed human footprints dated between 21,000 and 23,000 years old
Here's the twist: Later discoveries suggested Leakey may have been right—until recent research challenged them. Monte Verde (Chile, 1977) originally revealed wooden structures, stone tools, and butchered megafauna remains, suggesting human presence 14,500 years ago. White Sands in New Mexico has footprints dated between 21,000 and 23,000 years old. Bluefish Caves shows butchery marks from 24,000 years ago. But a 2026 study now questions Monte Verde's age—new data suggests the site dates much later than thought, potentially reshaping the pre-Clovis narrative. The paradigm is still being debated. 🏛️
