Early applications of this technique relied on Emanuel Margoliash’s observation of the genetic equidistance between cytochrome c in birds and mammals. For 10 points each:
[10m] Name this technique in which the mutation rate of proteins is cross-referenced with a fossil record to infer when two clades diverged.
ANSWER: molecular clock [accept gene clock or evolutionary clock]
[10e] Molecular clocks rely on Motoo Kimura’s observation that most mutations have this effect on fitness. Ignoring codon optimization, most gene mutations that don’t cause a change in amino acids have this effect on fitness.
ANSWER: neutral [accept equivalents like no change or zero; accept neutral theory of molecular evolution]
[10h] Unlike strict and unrooted models, this form of molecular clock analysis allows different phylogenetic branches to have different mutation rates. These molecular clocks are calculated by the BEAST algorithm.
ANSWER: relaxed molecular clock
