Impossible evolution of new beneficial proteins

You may take this as a reminder to be polite.Forum rule 3Respect for others is the rule here. Argue the position, not the person. The Britannica says, "Usually, in a well-conducted debate, speakers are either emotionally uncommitted or can preserve sufficient detachment to maintain a coolly academic approach."

The topic is beneficial proteins.Your question is off topic.You should be asking about the nature of the genetic changes and the resulting phenotype.

Well, there has been a bit of an increased push to stay on topic.The question I suggested looks like it would have, indeed, been relevant since the mice my not have anything to do with proteins. So you could have asked about that and found them to be irrelevant. (and off topic).
