    Definition technique in molecular evolution that uses fossil constraints and rates of molecular change to deduce the time in geologic history when two species or other taxa diverged Reference Wikipedia. Molecular clock http://en.wikipedia.org/wiki/Molecular_clock [2.12.2011]
    Comment It is used to estimate the time of occurrence of events called speciation or radiation. The molecular data used for such calculations is usually nucleotide sequences for DNA or amino acid sequences for proteins. It is sometimes called a gene clock or evolutionary clock.More more information, please see: University of California Museum of Paleontology. Understanding Evolution.
