Number of right-handed (R), left-handed (L), and ambidextrous (A) subjects by condition. Note the steady decrease in the number of ambidextrous subjects as the task demanded increasing bipedality, and roughly equivalent numbers of right- and left-handed animals with a slight bias towards right-handedness.
