Oh, really??? You can judge for yourself if these researchers were too quick in the draw... The title of the article itself usesw the word "MAY" - darlings, I don't know what schools you went to but when I went to school "may" was not a word one used when one wished to state a definitive conclusion.

RARE DNA VARIANT MAY DISPROVE PALEOLITHIC MIGRATION TO AMERICA ACROSS THE ATLANTIC
A new analysis of the rare mitochondrial DNA haplogroup C4c in Native American populations shows that it has a parallel genetic history with the X2a haplogroup thought by some to indicate a connection between early Paleoindians in eastern North America and the Upper Paleolithic Solutrean culture in France and Spain.
According to Baharak Hooshiar Kashani, of the Dipartimento di Genetica e
Microbiologia at the Universita di Pavia in Italy, and his several co-authors,
C4c has clear roots in Asia and is found in Great Lakes and Great Plains Native
American populations. These are the same areas in which the X2a haplogroup has
been identified suggesting that “these two lineages possibly arrived together
from Beringia with the same Paleo-Indian group(s) that entered North America
from Beringia through the ice-free corridor between the Laurentide and
Cordilleran ice sheets” at around 18-15,000 years ago.
The researchers further conclude that this finding “definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America.”
