I agree. When I look at the long term though, the environment and mutation are just different parts of the same whole. Both are necessary for phenotypic changes and speciation. Even that is simplistic. It doesn't take into account the significance of viral transfer of dna and other epigenetic factors, how an environment can cause normally dormant genes to express themselves, sexual selection where attractiveness != most environmentally fit, etc.
