Message: <blockquote data-quote="Fishalt" data-source="post: 65146" data-attributes="member: 228">That's not what I said at all. I specifically said that most mutations will either not be positive or will have no meaning. If you're asking me why we don't see negative mutations more commonly, the answer is quite simply; the organisms that presented them are dead. They didn't work. They were the chaff seperated from the wheat.A way to think of it is that genetics throw out random mutations, and environment decides whether or not these mutations work or don't. The driver of this process is sex and death.For what it's worth, I gave an example of moths. We can actually see evolution just like this quite recently in the Peppered moth. It became dark coloured during the Industrial revolution in industrial areas due to smog. Since the clean air act of 1956, the older type that is lighter coloured is becoming more common again.<a href="https://ageofrevolution.org/200-object/the-peppered-moth/" target="_blank">https://ageofrevolution.org/200-object/the-peppered-moth/</a></blockquote>
