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. All known populations of living human beings
apparently favor 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; explaining this variation appears to
require both cultural and environmental causal variables. 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 this Annals
volume come from anthropology, archaeology, genetics,
neurosciences, palaeo-anthropology, primatology, psychology, and
psychiatry. NOTE: Annals volumes are available for sale as
individual books or as a journal.
