Their large swellings are visible for weeks before and after their fertile periods, and there is never any discernibly wrong time to mate. Unlike most primate species, in which males usually take on the dangerous task of leaving home, among bonobos females are the ones who leave the group when they reach sexual maturity, around the age of eight, and work their way into unfamiliar groups. Living in separate places. Having identical alleles for a particular trait. The idea of emancipation, however, is many-sided, and its indefiniteness is increased by its association with many practical customs which have nothing to do with the theory of emancipation. Women were first allowed on the stage in the sixteenth century, and actresses date from that time. And what are we to say of the pelvis, that part of the skeleton in which, if anywhere, striking sexual differences exist? The fact is that every human being varies or oscillates between the maleness and the femaleness of his constitution. There is some evidence that male ducks who witness a mate undergoing forced copulation are more likely to abandon the female and her nest, presumably because the male can no longer be sure the nest contains his offspring. It can be shown that however distinctly unisexual an adult plant, animal or human being may be, there is always a certain persistence of the bisexual character, never a complete disappearance of the characters of the undeveloped sex.
