FORBIDDEN SILENT MUTATIONS. “New genes arise when existing genes are duplicated, undergo “forbidden mutations” as silent DNA, and reemerge as new genes with new functions. While silent, a gene cannot be improved or even maintained by natural selection. To arrive at a substantially different nucleotide sequence, we would expect many mutations to be required. These mutations will randomize the original sequence of the gene and it will lose its original meaning.”
