      I haven't read Calvin's new book, but I do recall once suggesting that
      throwing was important. It was brought to Calvin's attention, but I don't
      think he ever mentioned it. I think he should have referred to my ideas,
      but he did expand them in important ways in his J. Theoretical Biology
      article. Judge for yourself.

      "Not only are hand-eye and left-right hand coordination mechanisms, as
      used in making a hand axe for example...but also the ability to compute
      trajectories for throwing objects at moving animals (prey and predators)
      and for traversing the savannah econiche to find water sources, feeding
      areas, home bases, shelters, and spoors. Both humans and apes may...be
      capable of...underarm and overhead throwing motions, but only the human
      animal is capable of delivering great power, accuracy, and distance with
      overhead throwing and thrusting...The archaeological record...shows a
      large number of sperhoidal stone objects...that were most likely used as
      projectiles. Indeed, throwing objects with considerable force and accuracy
      over a significant distance must have been an important component of early
      hominid scavaging, hunting, and predator protection from the
      beginning...As far as I am aware, only the human brain is capable of
      complex computations and coordinations involving accurate and forceful
      throwing of objects at both moving and stationary targets. Indeed, is
      there any culture existing in which object-throwing is not a considerable
      component of both child and adult play, in which symbols, fantasies, and
      social control are operative?" pps. 409-410, in RL Holloway, 1975 Early

      I said essentially similar things in "Paleoneurological evidence for
