These particular Frenchies have to go down as some of the worst researchers in history, or we're reading some of the worst reporting, evah. According to Live Science, they've been studying them for about twelve years. Seems that in one picture, there's a guy holding one.In another journal, it looks like a different cat anesthetized and they're showing it's dentistry.
Even assuming it's the same moggie in both pics, couldn't they get clearer DNA results than some hair they scraped off a branch from a few years back? I mean, that babe on CSI (not the camel toe one, the one with the rack) only needs a five year old sweat stain. Or can they identify from the markers but the reporting just wants to leave the question open for future clicks. (The journalist seems to be legit, with credits at both Live Science and Scientific American but I'm not seeing a lot of field work. I doubt she traveled to Corsica for the article.)
