Molecular clock - Wikipedia

The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA, RNA, or amino acid sequences for … See more The notion of the existence of a so-called "molecular clock" was first attributed to Émile Zuckerkandl and Linus Pauling who, in 1962, noticed that the number of amino acid differences in hemoglobin between different lineages … See more To use molecular clocks to estimate divergence times, molecular clocks need to be "calibrated". This is because molecular data … See more The molecular clock technique is an important tool in molecular systematics, macroevolution, and phylogenetic comparative methods.
