Summary

Describes his view on colour [of plumage] of males and females – i.e., that absence of brilliant colour in either sex is due to need for protection in incubation, rather than to sexual selection.

To A. R. Wallace   29 April [1867]

Summary

Comments on ARW’s view of colouring in relation to sexual selection and protection. It is not new to CD. Hopes to discuss subject fully in his "Essay on Man" [Descent]. As to the problem of brightly coloured females, CD is not satisfied that it is due to males taking over incubation. Admires "value and beauty" of ARW’s generalisations.
