Handedness, or manual laterality of function, is thought to be both universal and unique to humans, making it a highly derived trait, based on an equally specialized neural substrate. By contrast, in various non-human species, both living and extinct, extent of lateralization varies: Some taxa are biased in the performance of particular behavioural patterns; others appear to be ambilateral. Some taxa are biased at individual, or family, or population, or species level.
All known populations of living human beings apparently favour the right hand, motorically, culturally, and symbolically, thus right-handedness is species-typical, as well as species-specific. This laterality of function is correlated with asymmetry of structure, that is, neural, skeletal and muscular, for example as manifest especially in skilled movement, such as handwriting. Human brains are lop-sided, and sagitally-paired organs (hand, foot, eye, ear, etc.) are skewed in their use, usually biased to the right.
This prompts the basic question: Why are humans so laterally biased? Or, to put it another way, why and how did humans evolve this peculiar trait? Current answers to these questions vary from consensual to confused: All human populations are right-biased, but to varying extents; explaining this variation appears to require both cultural and environmental causal variables. This puzzle will be the focus of the symposium.
To tackle these questions and advance our knowledge of this basic human trait requires genuinely multi-disciplinary input by scholars willing to think inter-disciplinarily. Thus, participants in the symposium come from anthropology, archaeology, genetics, neurosciences, palaeo-anthropology, primatology, psychology, and psychiatry.
