>>114650725The fact that mutants and humans can reproduce with each other without getting steryle offspring automatically means thay they're not yet a different species maybe they're clos to being one but are not completely one.
There's only up chucks species as precednt for something like this where although they're the same species because only the queen seems to be able to produce offsrpring and she presumably produces the two subspecies she is also apparantly a third species even off itself. The two different male subspecies are in the omnitrix yet for some dumb reason, DJW word of God, the female queen is not.
For an alien species that would need different selection on the omnitrix look no further than the gems who are more like rock computers
