100 years ago, biologists discovered they could generate DNA mutations with radiation, which was easy to do. They were excited because they believed they could now accelerate evolution. They tried experiments with fruit flies for decades. They learned a great deal about which genes perform certain functions… but as far as generating evolutionary events, those experiments were a total failure. There had to be something more to evolution that we didn’t understand.
