@jkanev hey, not sure, what you are refering to. The abandoned baby was an example that human babies during Ice Age did not survive if nobody loved them.
@Ullilust After the flies move on, out of the farm, they find a baby by a lake (third picture). The text says that there's no algorithm. Next picture (underneath) shows people listening to a plant, and then (forth page) walking in a long trail through the desert. Beautifully drawn by the way.
