The idea of an evolutionary molecular genetic clock has significantly impacted and influenced modern biology. The technique employs biological sequence comparisons between taxa to estimate rates of evolution and is routinely calibrated with deep-time estimates taken from paleontology. In addition to this evolutionary bias, the following problems also 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.
Furthermore, because the molecular clock idea is directly tied to the neutral model theory of evolution, recent discoveries in full codon utility and pervasive genomewide biochemical functionality utterly negate its foundational premises.
