No Sub-men In America
( Originally Published Early 1900's )
There is no convincing evidence of man in America before the end of the Pleistocene. The same relaxation of the climate that permitted the retreat of the reindeer hunters into Russia and Siberia, as the Neolithic tribes advanced, may have allowed them to wander across the land that is now cut by Bering Strait, and so reach the American continent. They spread thence southward, age by age. When they reached South America, they found the giant sloth (the Megatherium), the glyptodon, and many other extinct creatures, still flourishing. The glyptodon was a monstrous South American armadillo, and a human skeleton has been found by Roth buried beneath its huge tortoise-like shell.
All the human remains in America, even the earliest, it is to be a noted, are of an Amer-Indian character. In America there does not seem to have been any preceding races of sub-men. Man was fully man when he entered America. The old world was the nursery of the sub-races of mankind.
"The various finds of human remains in North America for which the geological antiquity has been claimed have been thus briefly passed wader review. In every instance where enough of the bones is preserved for comparison, the evidence bears witness against the geological antiquity of the remains and for their close affinity to or identity with the modern Indian."

But J. Deniker quotes evidence to show that eoliths and early palm oliths have been found in America. See his compact but full summary of the evidence and views for and against in his Races of Man.
