What is the popular theory about how Asian nomadic hunters arrived in North America?

Answer 1

The popular theory suggests that Asian nomadic hunters arrived in North America via a land bridge known as Beringia, which connected Siberia and Alaska during the last Ice Age. As sea levels were lower, this land bridge allowed these early humans to cross into North America in pursuit of migrating animals. This migration is believed to have occurred around 15,000 to 20,000 years ago, leading to the eventual settlement of the continent. Over time, these groups spread across North America, adapting to various environments and forming diverse cultures.
