No. Natural selection happens at the level of the phenotype not the genotype. Anyway a gene is not a piece of DNA, but a unit of heredity. The reason why epigentics is less important in evolution is because it is unstable. If an environmental factor can shift the phenotype one way then another factor can shift it back. Most of these unstable epigenetic changes wash out in an evolutionary short time frame. |
