Hemispheric specialization, and lateralized sensory, cognitive or
motor function of the left and right halves of the brain, commonly
manifests in humans as right-handedness and left hemisphere
specialization of language functions. Historically, this has been
considered a hallmark of, and unique to, human evolution. Some
theories propose that human right-handedness evolved in the context
of language and speech while others that it was a product of the
increasing motor demands associated with feeding or tool-use. In
the past 20-25 years, there has been a plethora of research in
animals on the topic of whether population-level asymmetries in
behavioral processes or neuro-anatomical structures exist in
animals, notably primates and people have begun to question the
historical assumptions that hemispheric specialization is unique to
humans.
This book brings together various summary chapters on the
expression of behavioral and neuro-anatomical asymmetries in
primates. Several chapters summarize entire families of primates
while others focus on genetic and non-genetic models of handedness
in humans and how they can be tested in non-human primates. In
addition, it makes explicit links between various theoretical
models of the development of handedness in humans with the observed
patterns of results in non-human primates. A second emphasis is on
comparative studies of handedness in primates. There is now enough
data in the literature across different species to present an
evolutionary tree for the emergence of handedness (and perhaps
other aspects of hemispheric specialization, such as
neuro-anatomical asymmetries) and its relation to specific
morphological and ecological adaptations in various primate
species.
* The first treatment of this important topic since 1998
* Examines the tenet that lateralization and handedness is a
uniquely human character through evidence from higer and lower
primates and with reference to other vertebrates.
* Advances our understanding of the occurrence, evolution and
significance of lateralization and handedness effects.
