	abstract = {<p>Early hominid evolution may have involved an interaction between lateralization to left brain of rapid motor sequencing (e.g., right handedness) and its selection via one-handed throwing of stones at small prey. Since a more redundant sequencer should permit faster orchestration of muscles, faster (and hence longer range) throws could have selected for encephalization. Secondary uses of the enlarged sequencer may have included tool-sharpening and manual gestures. Because an oral-facial sequencing area just below motor strip forms the core of modern language cortex, there may have been a common origin of handedness and language in redundant sequencing circuits selected by throwing success.</p>
