I said no such thing.
Indeed you did, in post# 342 you gave cancerous melanoma as the ONLY example to justify evolution. Not only does it not justify it, but because it is not genetic and it is not passed on to the next generation, it could not have anything to do with evolution.
For one thing, evolution needs no justification.
In other ways because you say evolution has been proven, everyone is supposed to take your word for it. Sorry, it does not work that way. You need to back up your statements. For evolution to be science it has to provide scientific facts proving it to be true. You certainly cannot provide such facts - and no one else can.
