This promises to tell us much about the origins of Clovis culture
and how it changed through time, how Clovis people met the challenges and opportunities of North and Central America, a land not previously known to them, and how they adapted to rapid and dramatic climate change during the closing phases of the last Ice Age.
The team of archaeologist David Meltzer, Southern Methodist University, Dallas, and a lead author on the study and an expert in the Clovis culture

Martin's progressively popular "Blitzkrieg" theory posits that humans, the Clovis culture
of present-day New Mexico in particular, caused the extermination of seventy-five percent of America's late Pleistocene megafauna--plodding giants that, relative to their African and Asian counterparts, were afforded precious little time to adapt to large-brained Homo sapiens who, by 13,000 years ago, had ably hunted with fluted stone points fastened to wooden shafts and portable spear levers called atlatl.
