I remember reading a long time ago that one author termed the ‘Land Bridge’ hypothesis of people migrating across the Bering Strait as bunk.
There had to be multiple migrations from different directions across a few hundred years to account for the numbers of people the Spanish encountered when they first arrived....................
It’s pretty clear at this point that migration was continual (not continuous) and in different directions over many thousands of years, just as it has been throughout the rest of the Earth.
Not really. With abundant resources, people multiply rapidly.
A small population (a couple dozen) can multiply to fill up the two continents in about a thousand years.
North and South America were filled with easily killed big game, which became extinct about the same time humans colonized the continents.
With few diseases, the humans had a golden age of hunting and producing more humans, until the continents filled enough for continual tribal warfare to become the norm.
Cortez found plenty of bronze/copper axes during the invasion of Mexico.
