This has nothing to do with propagating The species is continued as so many are (among the smaller creatures) by fission (and this species is very small next in order to the amoeba, the beginning one) The paramecium achieves, then, immortality by dividing But when the paramecium desires renewal strength another joy this is what the paramecium does: The paramecium lies down beside another paramecium Slowly inexplicably the exchange takes place in which some bits of the nucleus of each are exchanged for some bits of the nucleus of the other This is called the conjugation of the paramecium.
Muriel Rukeyser - 1913-1980
In the cave with a long-ago flare a woman stands, her arms up. Red twig, black twig, brown twig. A wall of leaping darkness over her. The men are out hunting in the early light But here in this flicker, one or two men, painting and a woman among them. Great living animals grow on the stone walls, their pelts, their eyes, their sex, their hearts, and the cave-painters touch them with life, red, brown, black, a woman among them, painting.
