No, as I'm pretty sure they're all dead by now.
However, they are probably mostly descended from them.
Nah. Read this:
"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."
