Loewe L & Hill WG 2010 The population genetics of mutations: good, bad and indifferent. Phil Trans R Soc Lond B 365:1153-1167. many advances in the past built on models that treat the evolution of mutations at each DNA site independently n…
Carroll SB 2005 Evolution at two levels: on genes and form. PLoS Biol 3:e245. in their classic paper "Evolution at Two Levels in Humans and Chimpanzees," published exactly 30 years ago, Mary-Claire King and Allan Wilson described the great…
Pennisi E 2008 Deciphering the genetics of evolution. Science 321:760-763. early suggestions that gene regulation could be important to evolution came in the 1970s from work by bacterial geneticists showing a link between gene expression a…
Patwa Z & Wahl LM 2008 The fixation probability of beneficial mutations. J R Soc Interface 5:1279-1289. Lambert pointed out that the factor 2 in Haldane's result of π ≈ 2s for very small s stems from the assumption that the offspring distr…
