Ah, I see...

Similar concept in Star Wars, which I am more familiar with.

Although for some reason Star Wars uses panspermia (Humans and Mandalorians both originate on Coruscant), and the criteria is mostly "can they interbreed and produce fertile offspring", rather than any ethical concerns...

Obviously Trek tackled these things, too, but I feel like that is too complex for me to bother reading up on, lol. And it seemed to flip flop depending on the series/era, too.

But I admittedly had not heard of the Star Wars test. Makes sense, though.

I suppose we could add Battlestar Galactica to this discussion, except that in that instance they are cyborgs rather than aliens. Man do they ever bone a lot (in the new series, more so than the old one), though...
