There is nothing about a random process that excludes duplication. The result of a dice throw is random, but seven will come up more than once.
When I said "primitive," I meant "rudimentary" not "uncivilized." Not that that really matters, since we're here to talk about Superman, not Star Trek, and we must isolate our various nerdy interests. Anyhow, with rolling dice, you have a 1 in 6 chance of getting 7, so duplication is inevitable with time. With evolution, you're basically dealing with odds of 1 out of infinity, so duplication is incredibly unlikely.
