Well, in Trek they tried to ret-con this in TNG by introducing the idea that there was a single progenitor humanoid race billions of years ago that seeded the galaxy with their genetic material. That's why so many planets look earthlike, and why so many aliens are humanoid.
Without this, we get no Jarael or Chantique (KOTOR is best era. Fight me), and Twi’ileks become harder to explain (they still don’t quite work with the other human-offshoots, but they can interbreed now, so there’s that)…
So… It works, even if it is a bit dubious…
Though I suspect most “Disney Star Wars” era fans wouldn’t even know that Mandalorians were originally a species, so I suppose all of this got rather lost along the way…

Panspermia. Not a new concept by any means…
Star Wars did this too. Because it was getting too… “Messy”, otherwise (pre-Disney)…
