give me one example of a mutation adding information to the genome in mammals.

(Pandas are a good example, their ability to grip things with their paws is considered to be a mutation that has benifited them, even if they are going extinct at the moment. Just look around. Mutations happen all the time, most of them do nothing, some of them are hinderances, and some of them are benificial. Just take a basic biology class or something.)

but thats just messing with existing code, thats all a mutation ever is.

(more refuting of his dumbassery)

i can change the word Christmas in many different arrangements, but you will NEVER get, queen or zebra, the letters or code is simply not available.

you still did not give me an example of a genetic code altering mutation that was beneficial.
