From A. R. Wallace 4 October 1868
Summary
Sexual differences in coloration. Sexual selection versus natural selection as explanations. ARW continues to argue against sexual selection, saying that natural selection, in keeping the female dull for protection, would account for differences in sexual colouring more effectively than inheritance and partial transmission of sexually selected male colours. Colours of female birds of paradise. Protective coloration. Disagrees with CD on coincidence of hidden nests and bright colours of females.
