That’s the criteria for distinguishing species and subspecies, though, isn’t it? If two specimen can produce non-sterile offspring, they’re the same species.
Oh that’s what you were saying, now I see. Yes, that’s usually true. I thought you were saying because modern humans have Neanderthal ancestors, we’re the same species.
Well, also yes, ipso facto? If we’re offspring of sapiens sapiens and sapiens neanderthalis, that means they had viable offsprings together, therefore they’re the same species, QED…

I wasn’t disagreeing.
That’s what I was taught 35-years ago, but from comments I’ve read, I gather there’s a lot of disagreement in biology these days.
