What would an Orion/Andorian hybrid look like, aqua perhaps.
Anyway you can have any number of hybrids because that archaeology alien left a recording to say how they were all seeded from the same species.
No, that doesn't even come close to cutting it. As I have repeated several times (though some feel justified to ignore it), evolution does not work that way. No species evolves in a vacuum. The evolution of all species is directed by their environment and their relationship to other species. You can't throw DNA strands into the primordial soup of disparate worlds and predict the outcome - unless you can see the future. Even if you could do that, it would still be impossible for species with radically different physiologies like Vulcans and Andorians to produce natural offspring - regardless of common origins.
