16845Calvin's new book, throwing, etc..
- Jan 31, 2002I 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
