Human is such a flaky word, and species isn’t much better. I’d bet there could be a situation in which they can successfully interbreed with relatively modern humans and still produce viable offspring, so still the same species. Human doesn’t even require homo sapiens though. It can include other species that have the traits of humans.
You’re not wrong. One group will displace the other, though. Some of us Homo Sapiens still have genes from Homo Neanderthalensis. Neanderthals aren’t around anymore, though. Also, archeological evidence suggests they didn’t spend much time together.
