Question

what do scientists theorize happend after the first american arriving by boats exploded coastal areas have

Answer 1

For more than a half-century, the accepted story of how the first humans arrived in the Americas was as follows: Around 13,000 years ago, small groups of Stone Age hunters crossed a land bridge connecting eastern Siberia and western Alaska, eventually making their way down an ice-free inland corridor into the heart of North America. These progenitors of today's Native Americans developed a rich civilisation by chasing steppe bison, woolly mammoths, and other enormous beasts across two continents to the tip of South America.

That version of events, however, has taken a battering in recent years, not least due to the finding of archaeological sites in North and South America indicating that humans had been on the continent for 1,000 or even 2,000 years.
