There is considerable evidence that Darwinian mechanisms have creative power in fact, several thousand reports covering hundreds of incidents. In fact, random mutation accounts for life as we see it, but also requires the premise that there was no plan and what we see today is the result of chance. Scientists do not necessarily believe all there is in the universe is matter and the laws of physics and chemistry.
Evolutionary theory is arguably the most thoroughly tested theory in science.
It not only underpins all of biology, it is the only theory supported to some degree by virtually every other scientific discipline. Many scientists, in fields including and beyond biology, have used the same methods as all the other fields of science to discover, test and defend evolutionary theory. To disparage evolution with a sweep leaves us to equally disregard electric lights, automobiles, computers, medicine. Johnson is a lawyer, gifted with tenure at a major center of evolutionary study, but in a different department and with no biological credentials. We as a free society must either show up such specious arguments for the non-scientific propaganda they are or accede to the asinine demands of a vocal minority to corrupt the kind of thinking that gives us the lifestyles and knowledge of our universe that we have.
