The term "Paleo-Indian" refers to the earliest known inhabitants of the Americas, who lived during the last Ice Age, approximately 15,000 to 10,000 years ago. These hunter-gatherers are recognized for their distinctive stone tools, such as spear points, which were used for hunting large game like mammoths and mastodons. Their nomadic lifestyle involved following animal migrations and seasonal plant availability. Paleo-Indians are believed to have migrated from Asia across the Bering Land Bridge, a land connection that existed between Siberia and Alaska. Archaeological sites, such as Clovis and Folsom, provide evidence of their existence and cultural practices, showcasing their adaptability to diverse environments across the continent.
