Good Science Fiction

From E.O. Wilson in the New Yorker:

The only thing that he had ever done was accept meals regurgitated to him by his sisters, as if he were a nestling bird, and wait, and wait some more, and finally take the one short flight from his home, followed by five minutes of copulation. In other words, the male was no more than a guided missile loaded with sperm, his life’s work a single ejaculation. Afterward, he was left with only one instruction, to be enforced if necessary by his sisters: Don’t come back.
