Well, that's also arguing that a morphology of people with broad, flat noses is type specific of African negroid populations. Many sub-groups of the mongoloid races have broad flat noses, and we have a demonstrable route by which a mongoloid people could have arrived without the need of any maritime technology whatsoever. (Ignoring Solutreanism, which I'm insufficiently familiar with to speculate on the morphological features of the head and face of possible Solutrean migrations.) This is also ignoring the possibility of convergent evolution, or of migratory stock whom we have no knowledge of the facial morphology of (peoples whose culture is more or less silent in history).
The original immigrants into America could not be readily said to be mongoloid. It seems the set of features commonly used to distinguish mongoloids evolved after the end of ice age and the permanent separation of Asian and American human populations. American Indians probably derived from a population that were also ancestral to range of groups in central and northeastern Asia.
