Show moreDarwin writes to say that he has read Grant Allen's book (The colour-sense with "great interest" and also offers some criticisms and suggestions. Darwin does not believe Allen's theory of the origin of pleasure and pain, though he agrees with his defense of sexual selection. Darwin finds A.R. Wallace's explanations "mere empty words", and also doubts Wallace's scientific judgment. Darwin goes on to say that the possible effect of environmental color on the color tastes of animals.

Show moreThanks Grant Allen for his article, "The daisy's pedigree", Cornhill Mag. 44 (1881): 168–81. Darwin writes that the evolutionary argument that petals are transformed stamens is “striking and apparently valid”. He doubts petals are naturally yellow. A. R. Wallace’s “generalization about much modified parts being splendidly coloured” is also dubious except as both are caused by sexual selection. . Letter from Down, Beckenham, Kent. Transcription: "Jan 2nd 188[9] Down, Beckenham, Kent. Railway Station Orpington.S.E.R. My dear sir I thank you for sending me the [], as your article has interested me much. Many years ago I thought it highly probable that petals were in all cases transformed stamens. I forgot ([] the water-lily) what made me think so; but I am sure that your evolutionary argument never occurred to me, as it is too striking + apparently valid ever to be forgotten. I cannot help [] about petals being naturally yellow. I speak only from vague memory, but I think that the filaments are generally white or almost white, + [surely] it is the filament which is [] with the petal.

I must doubt Wallace's [] about much mobilized parts being splendidly coloured, except"
