Are there favourable mutations?
It is possible. Within neutral genes there can (in a manner of speaking) be mutated to ones hearts desire, because these genes are not important for the viability of an individual. They often do appoint the characteristics of the external form of appearance (the phenotype) and therefore cause many varieties. But in most cases even when it concerns neutral genes, mutations just damage or completely terminate the gene or protein. Nevertheless, even the termination of a gene can produce a surviving advantage, as is the case with the polar fox, polar bear or the snow goat that all have lost some genes that produce pigment in the fur. Among essential genes no useful mutations occur. A change of function of the gene or protein will lead to a form of degeneration, because it also influences the viability. In essence, that is within the essential genes, a species always stays the same! Mutations are being grossly over-appreciated by evolutionists. • Most of the biological changes proceed from
