Final answer:
Human arrival in North America was likely via the Bering Land Bridge and coastal migration, with subsequent migrations populating the region. The Solutrean hypothesis is contested, and questions persist about pre-Clovis populations and migration routes.
Explanation:
The first human beings arrived in North America through two main theories: the Bering Land Bridge and coastal migration. Most archaeologists support both theories, dating human arrival to 20,000-14,000 BP.
The Solutrean hypothesis, proposing European descent, is controversial and genetic studies refute it. Subsequent migrations populated the Americas post-initial settlement.
Questions remain about pre-Clovis populations and migration routes, with some considering seaborne or European migration theories.
