Non responsive answer.
In simplest and simplistic terms, "right" morally is that which provides the best chance for your genes to propogate.
Nonsense. A thing can be correct or incorrect for a specific purpose, but morality isn't part of it.
Thus murder is out, because people will come kill you for it; rape is out for the same reason.
Incorrect. Getting CAUGHT for murder is out. Getting CAUGHT for rape is out. What you are saying basically means murder and rape are acceptable if you can get away with them.
I've yet to come across a bit of (generally accepted) morality that can't be defined in this way.
You haven't tried very hard.
> Incorrect. Getting CAUGHT for murder is out. Getting CAUGHT for rape is out.
Nope. Committing such acts greatly increases the risk to yourself and your potential progeny, at no gain. On a very basic level, these things do not pass the cost/benefit analysis required by the drive to reproduce. Over the last million or more years, as we evolved from a smart ape-like critter to the more or less civilized species we are now, this very basic math have been transmuted into morality. That's why there are a number of acts that are pretty much *universally* considered immoral.

You convince people that God told you to do so?
