The leading theory about how early humans arrived on the American continent is called the Beringia land bridge theory. According to this theory, it is believed that around 20,000 to 25,000 years ago, during the last Ice Age, sea levels were much lower, and a land bridge known as Beringia emerged between present-day Siberia and Alaska. It is proposed that early humans, known as Paleo-Indians, migrated across this land bridge in pursuit of large game animals, eventually populating the American continent. As the Ice Age ended and sea levels rose, the land bridge was submerged, cutting off direct contact between Asia and the Americas.
The leading theory about how early humans arrived on the American continent is called the "Bering Land Bridge" or the "Beringia Theory." According to this theory, around 20,000 to 25,000 years ago, a land bridge called Beringia existed between modern-day Siberia in Russia and Alaska in North America. This land bridge emerged due to lower sea levels during the last Ice Age, and it provided a migration route for early humans who crossed over from Asia into North America. It is believed that these early humans, referred to as Paleo-Indians, migrated southward over thousands of years, eventually populating the entire American continent. This theory is supported by archaeological evidence, such as the presence of stone tools and artifacts found along the proposed migration route, as well as genetic and skeletal studies of indigenous populations in the Americas. However, it is important to note that new research and discoveries can lead to revisions or modifications of this theory in the future.
