My main research interest is in the evolution of complex action systems. In the context of the history of thought this has been a neglected topic, and this remains the case in modern cognitive science. It has been primarily concerned with apprehension of the world and with mental operations, rather than with the role of action on the world, which is central from a Darwinian perspective. I have developed a theory of the evolution of handedness and a theory of the evolution of speech (see references below) in an attempt to help remedy this neglect. According to the handedness theory, the original specialization of the left hemisphere of the brain in primates was for body postural control, complementary to a left hand - right hemisphere specialization for predation in prosimians. It is proposed that left hemisphere specialization for both right handedness in higher primates and speech in humans derived from this initial postural specialization. It is also proposed that the mouth open-close alteration which provides the "frame" for syllables evolved from ingestive cyclicities such as chewing via an intermediate stage of visuofacial communicative cyclicities, such as lipsmacks, which are common in other higher primates. My research program primarily consists of ethological studies of acquisition of speech in the hope that speech ontogeny will throw light on phylogeny.
