The title seems inline with the quotes from experts:

> “My first reaction on reading this paper was ‘No. This is wrong. Something’s wrong,'” said stone tool expert John McNabb of the University of Southampton in Britain. “If it does turn out to be true, it changes absolutely everything.”

And

> “This discovery is rewriting our understanding of when humans reached the New World,” Judy Gradwohl, president and CEO of the San Diego Natural History Museum, said in a statement.

Those quotes were probably cherry picked and a little out of context, but when experts in the field use such strong language, I think it's justified for reporters to do the same.
