The argument can be applied to all species - it is engrained in the ongoing diversification process of life itself: all species by definition have traits that set them apart from others, more or less radically. It is mostly a matter of what perspective you want to apply: are the differences the most important, or the similarities. But the main point I was trying to make was really this: > To the extent we have any unique such traits currently that radically sets us apart from other species then it has been a long and gradual process over eons I.e. there is no need to find a specific point where all that makes us human came into place. It all happened gradually, albeit with some leaps and bounds for different traits, at different times for different things, and we carry the legacy of all those millions of years with us, not just the last 200 KY. And we share substantial amounts of traits with other species.
