Wrong.
Then under evolutionary theory it is neither better or worse for a species to survive?
The creatures that survive are simply the creatures that are best adapted for an environment.
OK, "creatures that survive" are "better adapted" than other creatures. In other words, they are superior to other creatures in their adaptation.
Had the enfironment been different, a different species might have survived and the current "superior" species might have died out.
There is no futurabilia in the deterministic universe of evolutionary theory. Everything must occur the way that it does. The species that survives must be better adapted than the species that don't survive. Period.
Superiority only goes as far as the environmental factors. It's all relative.
The species that survives is superior. This isn't a relativistic statement, it is a definition at the core of evolutionary theory.
"Superior" only in that they survived, which is a tautology.
No, this is a very particular definition. "Superior" in this case (evolutionary theory) refers to creatures who survive. The term in everyday language is used much more broadly.
Therefore, those who practice genocide are superior to those who are victims of it.
Not if those who practice genocide find themselves getting executed for their crimes.
Before their execution, they are superior. After their execution, they aren't superior. So survival superiority is dependent upon chronology. In fact, survival superiority is so dependent upon time that it is meaningless, except in cases of complete extinction of a species. And then, who's to say that, under evolutionary theory, that the extinct species will not arise again?
And again, this only defines superiorty through those who survive. Genetics doesn't even play into it...
How does genetics "play into it"?
...you just kill a group of people and call yourself "superior" simply because you didn't end up dead. That's not evolution, that's just mass-murder.
Lions wipe out a species of deer and this is called evolution. One race of people wipes out another race of people and this is called "mass-murder." Yet people are also supposed to have evolved, just like deer and lions. This is a contradiction.
