The designation "Neomuran revolution" refers to the appearances of your typical ancestors of eukaryotes and archaea. Cavalier-Smith proposes that the 1st neomurans emerged 850 million a long time in the past. Other molecular biologists assume that this group appeared Substantially earlier, but Cavalier-Smith dismisses these claims mainly because they are depending on the "theoretically and empirically" unsound design of molecular clocks. Cavalier-Smith's idea from the Neomuran revolution has implications for your evolutionary historical past of your mobile equipment for recombination and sex.
