at those who hurl
stones at them from below, from the fact that the cocoanut seems too
heavy and too firmly fixed to its support for the strength of those
small species, but it is not uncommon for them to throw lighter objects.
Yet in doing this they usually seem to have no idea of aim, but toss the
missile aimlessly into the air. Of the large apes, the orang will break
off branches and fling them at its tormentors, or will throw the thick
husks of the durian fruit, but with similar lack of aim. The most
skilful in this exercise are some species of baboons, which can hurl
branches, stones, or hard clods with much dexterity.
It is of interest to find existing apes availing themselves of their
grasping power in this manner, since it leads us irresistibly to the
conclusion that the man-ape may have done the same thing. The species
which use missiles fail to take aim for two reasons, one that they
employ them only occasionally, often in imitation of human action, the
other that their arms are ill suited to this motion from their constant
employment in another duty. In the case of the man-ape we may justly
look for a more effective result, since if the arms became relieved from
duty in locomotion they were free to gain facility of action in other
directions.
If in addition to this the man-ape began to use missiles with a definite
purpose in view, that of striking down animal prey, so that the use of
such weapons became habitual instead of occasional, it would soon gain
some power of aim and a growing strength and skill in the throwing
motion. It is quite probable, also, that an early use of weapons was in
the form of clubs, which were retained in the grasp to strike down the
prey when overtaken. In this case, we may imagine our primitive biped
running swiftly after its prey, club in hand, striking at it when within
reach; or, if it should prove too swift, hurling the club or a stone
through the air with the hope of bringing it down in this manner. Such a
flinging action, if now and then successful, would be likely soon to
become habitual; while the arm would grow accustomed to this new motion,
and attain skill in taking aim. We may reasonably infer, also, that the
club would be used for defence as well as for offence, in case the
man-ape were in its turn pursued by larger animals. Instead of fleeing
to the nearest tree, it might now stand its ground and beat off its
enemy.
All must admit the probability, in a large tri
