The Anzick genome proves Clovis is first, after all

The close relatives who buried the Anzick infant ca. 12,800 cal BP made classic Clovis tools and were unequivocally the lineal genetic ancestors of all the living Native peoples of southern North America, Central America, and South America. Clovis-derived Fell I fishtail points track the rapid southward migration of this ancestral population all the way to Tierra del Fuego. Any hypothesized earlier populations, if they (improbably) ever existed, must have been replaced or genetically swamped by these Clovis descendants.
