From the foregoing discussion on the various laws of inheritance, we learn that the characters of the parents often, or even generally, tend to become developed in the offspring of the same sex, at the same age, and periodically at the same season of the year, in which they first appeared in the parents. But these rules owing to unknown causes, are far from being fixed. Hence during the modification of a species, the successive changes may readily be transmitted in differet ways; some to one sex and some to both; some to the offspring at one age, and some to the offspring at all ages. Not only are the laws of inheritance extremely complex, but so are the causes which induce and govern variability. The variations thus induced are preserved and accumulated by sexual selection, which is in itself an extremely complex affair, depending as it does, on the ardor in love, the courage, and the rivalry of the males, as well as on the power of perception, the taste and will of the female. Sexual selection will also be largely dominated by natural selection tending towards the general welfare of the species. . . . Page 249
