by Octavia E. Butler

“Why can’t you go back to your homeworld?” she asked. “It … still exists, doesn’t it?” He seemed to think for a moment. “We left it so long ago … I doubt that it does still exist.” “Why did you leave?” “It was a womb. The time had come for us to be born.” She smiled sadly. “There were humans who thought that way—right up to the moment the missiles were fired. People who believed space was our destiny. I believed it myself.” “I know—though from what the ooloi have told me, your people could not have fulfilled that destiny. Their own bodies handicapped them.” “Their … our bodies? What do you mean? We’ve been into space. There’s nothing about our bodies that prevented—” “Your bodies are fatally flawed. The ooloi perceived this at once. At first it was very hard for them to touch you. Then you became an obsession with them. Now it’s hard for them to let you alone.” “What are you talking about?” “You have a mismatched pair of genetic characteristics. Either alone would have been useful, would have aided the survival of your species. But the two together are lethal. It was only a matter of time before they destroyed you.”
