DOES EVOLUTION THEORY NEED A RETHINK?

If you had read the nature opinion piece you would know that nothing much is going to change with respect to IDiots and other Biblical creationists. This just doesn't matter for creationists.
Take their claims that there is more to inheritance than genes. We have known this since the beginning of the modern synthesis, before we knew what a gene was.
Genes + environment = phenotype.
Look it up. This has been known to be the case before we had the modern synthesis, before we knew what genes were. The opinion piece only wants to claim that the phenotypic changes due to environmental causes can aid natural selection. The equation doesn't have to change. The results will be the same. It has been known for a very long time that the environmental changes could broaden the range of phenotypes that you could get from any specific genotype. It is no surprise to anyone that if the phenotype can be bent towards something that allows a genotype to exploit some new resource or have some selective advantage in that environment that it can act as a temporary boost for that genotype, and that new mutations or resorting of existing variation with that genotype can result in the genome being better adapted to that environment. They aren't changing anything, they are just stating the obvious. The environment can influence phenotype. If an environmental influence changes the phenotype in such a way that, that specific genotype has some selective advantage in that environment, the genotype can be selected for in that environment. Other genetic variation can make the adaptation even better.
It can be complex. A shift in temperature could cause a phenotypic change that better adapted the organism to living in a rocky area, so that genotype could be selected for in a rocky area under those temperature conditions. Add a few more genetic variants and you may no longer need the environmental boost to compete in that new environment. No matter how complex or whether or not the phenotypic change has some advantage in that environment, nothing changes in terms of what we know about how the environment affects phenotype.
IDiots and other anti-evolution creationists are just out of luck on this one.
