Or that the lines delineating human and proto-human species are blurrier than traditional taxonomy is adequate to describe. We don't have DNA samples from specimens that ancient, AFAIK.

That too. I've often wondered how many of the specimens we have were not actually from a separate species, but rather, just outlier specimens of the same species.

And how many outliers of other species have been misidentified as belonging to various proto-humans, too.

Without DNA analysis, we're really just guessing. What if they were looking at the fossilized remains of all of today's 300+ breeds of dog, with all the variation those encompass? would they be ID'd as 300 different species??
