Points? Heck, we have their heads. See below:
"The oldest human remains found in the Americas were recently "discovered" in the storeroom of Mexico's National Museum of Anthropology. Found in central Mexico in 1959, the five skulls were radiocarbon dated by a team of researchers from the United Kingdom and Mexico and found to be 13,000 years old. They pre-date the Clovis culture by a couple thousand years, adding to the growing evidence against the Clovis-first model for the first peopling of the Americas."
Of additional significance is the shape of the skulls, which are described as long and narrow, very unlike those of modern Native Americans.
They are similar but I think the problem lies in the dating. They are from different time periods.
But a very early European element in the North American Indian population isn't that far fetched in my opinion.
Despite popular belief, there was SIGNIFICANT difference anatomically between the many tribes in North and South America and an African element in South America isn't out of the question.
