There was a number of migrations across Beringia to the new world.
the earliest could have happened as far back a 35.000 BCE
Early ones (pre clovis and/or clovis)may have not been from east central Asia but my have been a Caucasian group/s displaced by the east central Asia
groups and/or from europe.(Solutrean hypothesis)
It is possible for a group of people to have followed the North Atlantic ice sheet from europe.
Then you have the mystery of the chicken and the sweet potato (Polynesian trans-oceanic)
Chicken bones found at the site El Arenal near the Arauco Peninsula in Chile support a pre-Columbian introduction of chicken to South America. The
bones found in Chile were radiocarbon-dated to between 1304 and 1424, before the arrival of the Spanish. DNA sequences taken were matched to those of
chickens in American Samoa and Tonga,
The sweet potato, which is native to the Americas, was widespread in Polynesia when Europeans first reached the Pacific. Sweet potato has been
radiocarbon-dated in the Cook Islands to 1000 CE, and current thinking is that it was brought to central Polynesia c. 700 CE and spread across
Polynesia from there. It has been suggested that it was brought by Polynesians who had traveled to South America and back, or that South Americans
brought it to the Pacific. It is unlikely that the plant could successfully float across the ocean by natural means.
Then you have Traces of coca and nicotine found in some Egyptian mummies.
These are both from new world plants.
Another curious thing is Spirit Cave man and Wizard's Beach man along with Kennewick Man and Arlington Springs woman were all water people.
Kennewick Man, Arlington Springs woman,Prince of Wales Island Man, Eve of Naharon(Eva de Naharon dated at 13,600 years old) were sea coastal .
Spirit Cave man and Wizard's Beach man were people that lived along the large
ancient fresh water lakes of Nevada.
The topper site is also coastal and may date as old as 50,000 BCE
This all leads me to believe The first Americans did use boats and were at ease on water and may have been boat/sail people from ether Siberia or
And spread down both coast by boat/sail and could have been Caucasian. both Pre Clovis and Clovis cultures
fit this. but the Pre Clovis culture did not have the weapons/stone tech of the later Clovis.
The later native Americans were foot people and spread by walking.
Another interesting point is A projectile found lodged in the hip of Kennewick Man was leaf-shaped, long, broad and had serrated edges known as a
Cascade point and this was the dividing period when Clovis was disappearing and the later Folsom/Cascade culture
Were the remaining Clovis people being killed off by the later group(Folsom/Cascade) because of racial differences. (race war???)
