Since its first use in the early 1960s, molecular genetic clock methodologies assume evolution and deep-time calibrations taken from paleontology. In addition, the following problems plague its use: 1) different genes/sequences give widely different evolutionary rates, 2) different taxa exhibit different rates for homologous sequences, and 3) divergence dates commonly disagree with paleontology despite being calibrated by it. Because the molecular clock idea is directly tied to the neutral model theory of evolution, recent discoveries in full codon utility and pervasive genome-wide biochemical functionality negate its foundational premise.
