Controversial: http://en.wikipedia.org/wiki/Neanderthal_admixture_theory—but in any case, 1%-4% of the genome? That’s close enough to extinction...if coyotes interbred with dogs, and lots of household dogs had 1%-4% coyote DNA in them, but there would be no coyotes in the wild, I’d treat it as “extinct enough for me.” :)
