Biringia
Beringia refers to the region that once connected Asia and North America, specifically the area around the modern-day Bering Strait, including parts of eastern Siberia, Alaska, and the surrounding sea. During the last Ice Age (approximately 20,000 to 15,000 years ago), sea levels were much lower than today because large amounts of water were trapped in the form of ice. -
How humans come to America
Humans are believed to have come to the Americas primarily via the Bering Land Bridge, a land connection that once existed between northeastern Asia (modern-day Siberia) and North America (modern-day Alaska) during the last Ice Age. -
Migrants
The question of whether the Americas were first inhabited by a single wave of migrants or multiple waves is a topic of ongoing research and debate among archaeologists, geneticists, and anthropologists.
