Then RM & NS Created Them Male And Female

Absolutely. Every conceivable variation. "Oh, they would have died off because they couldn't adapt.'

There's actually a pretty extensive literature about the origin of various kinds of symmetry (bilateral, radial, etc.) and how the forces of symmetry work in practice. How DOES biology enforce symmetry, so that one arm or leg will match the other, and mutations affecting one affect both? And how come bilaterally symmetrical organisms nonetheless have asymmetric aspects (i.e. humans have single copies of organs not centrally located, etc.)? These are interesting questions, and a good theory should explain why things happen as they do. A theory is not required to explain why things do NOT happen as they don't, except as a side-effect.

At any rate, symmetry is not enforced by selection, as even a cursory reading would point out, to those willing to do cursory reading.

Is that what you meant to say ?
' how the forces of symmetry work in practice.'
' symmetry is not enforced by selection.'

Yes, that's what I meant to say. Symmetry isn't a matter of selection. For example, longer or shorter PAIRS of legs might be selected, but if both legs are always approximately the same length, asymmetric legs aren't selected because they are not instantiated - selection cannot reject what it never sees. Here's some good information explaining that symmetry is built into the hox genes, which are ancient and much the same across the animal kingdom. These genes enforce symmetry, not selection.

Ah yes, the Hox gene.
' selection cannot reject what it never sees. '
This lamb never happened?

The hox gene tells us nothing. We expect to see all kinds of mutations and we do. However we do not see mutations of nice successful 6 legged lambs - which is what evolution demands.

If that lamb were to breed, would you expect the offspring to have too many legs also? This is an open-book question, so you can look up the answer. You can even provide a link to where you found the answer. You might even suggest an EXPLANATION of the answer.

But I don't plan to wait up for any hint of honesty.

Several others have tried in vain to explain this to him including a few who don't accept evolution.

I suggest you look for a mutant lamb with an even number of new mutated legs that has bred children with similar legs.

This dishonest charade of 'even mutations in evolution' has been exposed.

I'm not waiting up. I knew that when challenged to support your claim, you'd start evading.

This lamb is impossible (and can't breed children with 5 legs) :

but this lamb shows how evolution works because it happens all the time and it breeds six legged children:
