Only a cetain percentage is allowed to be diamond <| sep |> Please read my previous comment , I addressed your generation points in that . About radiations there are no sources of beneficial or harmful mutations . Mutations are random . Most of them are neutral or detrimental , only a few random one will be beneficial and maybe not even for the individual who receives them but for some of its offspring . Harmful mutations are weeded out simply because their bearers tend to die out quicker , typically before reaching reproduction age . We shield ourselves from radiations because they tend to give cancer , a slightly different effect . But we do have processes where we improve seeds by exposing them to radiations usually high frequency UVs and sort the ones that perform better . We know this works in controlled conditions .
