It had not taken long for the other Eves to make similar calculations. As Arkies, picked in the Casting of Lots, Camila and Aïda were younger than the others, with two to three decades of fertility ahead of them. If they decided to become baby factories, and if they were lucky, each of them could conceivably bear as many as twenty children before menopause. Dinah, Ivy, Moira, and Tekla, all in their early thirties, might bear a few each. Roughly speaking, therefore, those four had as much combined childbearing power, if you wanted to think about it that way, as the younger pair of Camila and Aïda.
