It was suggested that the hairlessless of humans represented the retention of a fetal condition in adults. It is my under- standing that fetal humans are covered with hair (lanugo) which is often (generally?) lost before birth. Does this fit into this discussion? Does toothlessness in baleen whales represent the retention of a fetal characteristic (they have teeth as fetuses)? -- Name: Jim Rising Mail: Dept. Zoology, Univ.
