What: "The second point is how the fixation of a neutral allele in a population is like radioactive decay; and it's like it in this sense: in neither the case of the fixation of neutral alleles, nor in the case of say looking at a gram of uranium-238, do you know which mutation will be fixed or which atom will decay. But, because there's so many of them, in both cases you know very precisely how many events will happen in a certain period of time." See the whole lecture for more details of an allele as a molecular clock.
