Clovis First model being rejected by archaeologists. The traditional Clovis First model states humans arrived in the Americas about 12,000-13,000 years ago Most archaeologists now accept that evidence pushes human presence back to around 20,000-22,000 years Clovis projectile points are considered the most sophisticated ever created in the Americas

Evidence for pre-Clovis human occupation is mounting, challenging the Clovis First model. 🦣

Key facts:

• The traditional Clovis First model states humans arrived in the Americas about 12,000-13,000 years ago ✓

• Pre-Clovis evidence has pushed human presence back to around 20,000-22,000 years at some sites (though the exact degree of acceptance among archaeologists remains debated)

• Clovis projectile points are considered among the most sophisticated flaked stone technologies in the Americas

• The theory is that humans would have developed sophisticated tools over time, not arrived with them

• Early humans faced dangerous megafauna in North America
