Silent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation. The phrase silent mutation is often used interchangeably with the phrase synonymous mutation; however, synonymous mutations are not always silent, nor vice versa.
Because of the difference in the genetic makeup of those with the beak shape, their population evolves to a higher level of adaptation. I think it should be fewer mutated.
