If Whenever some or most many of the successive variations have occurred early in life, the young males will will partake in a less or greater degree of the characters of the adult males. Differences of this kind between the old & the young males may frequently be observed with many animals, for instance with birds.

It is probable that young male animals have often tended to vary in a manner which would not only have been of no advantage use to them at an early age, but would have been actually injurious,─ as in the acquisition of bright colours, which would have rendered them conspicuous to their enemies, or of structures, such as great horns, which would have expended in their development much vital force. Variations of this kind occurring in the young males would almost certainly have been

(As variations analogous to those which give to the male an advantage superiority over other males in fighting, with other males, or in finding, securing, or charming the opposite sex, would, if they happened to arise in himthe female be of no service to her, the female, they will not have been preserved through sexual selection in this sex.

We have good evidence with domesticated animals that variations of all kinds ie soon lost through intercrossing & accidental deaths, if they are not carefully selected. Consequently variations of the above kind, if they chanced to arise in the female, would be extremely viable to be lost; & the females would be left unmodified, as far as these characters are concerned, excepting in so far as they were acquired received through transference from the males. No doubt, if the females varied & transferredmitted their newly acquired characters to their offspring of both sexes, those characters thosewhich were advantageous to the males would be preserved through sexual selection, although they were of no use to the females themselves. In this case
