Is there anyplace I can read up on other beneficial mutations?
Let's see... Here's one relating to mosquitos, known to have occurred after 1984. Here are a few examples, including the bacteria that eat Nylon, something not found in nature. Here's an extended description of the evidence that the blood clotting mechanism in vertebrates evolved by several gene duplications & modifications from the common ancestor.
Some mutations are pretty obviously "beneficial" or "harmful", but the interesting thing is, beneficial is only meaningful in the context of the organism's environment. So there's no absolute measure of beneficial-ness, outside of actually putting the organisms into a specific environment.
