Yes but draw an arbitrary line around any group. Call them HNdrathals if you want. Define them at one instaneous snapshot in time as 100% conserved gene corpus. Then watch generation after generation, as some of the HNers (against all odds) interbreed with the surrounding populace. After one hundred generations, should we expect many people to be more than 2% HNdrathal? Yet did the HNdrathals ‘die out’?
Careful, HNers are a population with a history of trauma associated with unclosed parentheses. By raising our cortisol levels you may be lowering our fertility rate by exposing us to them.
Thanks, edited along w/ several other typos (checks glasses prescription) :)
Wait, what? (Didn’t that ruin the joke?

Ok. but ancestral groups are in no way "arbitrary" when it comes to DNA. So what's your point?
They are, a bit, we define quite broadly and there is “fuzz” at the borders of countries.
I lean your way of course, it’s not totally arbitrary, but where we draw a line tends to be a bit arbitrary.
