> " When you were born did your uncle(s) and cousins go *poof* into nothing-ness?"

No they didn't.
But I didn't evolve into a different species either.

No they didn't. They're still H. sapien I suppose.

But they are different H. sapien(s) with subtle differences in hair, eyes, blood type, and a whole host of other distinctions. And their descendants will be different from your descendants, even more so.
And so on, etc.

Eventually you get to a point where a reasonable person will acknowledge the difference in degree has become a difference in kind.

And what do you suppose humans will become next?
