One reason for the apparent gulf between animal and human communication systems is that
the focus has been on the presence or the absence of language as a complex expressive …

Within the evolutionary framework about the origin of human handedness and hemispheric
specialization for language, the question of expression of population‐level manual biases in …

Handedness and brain asymmetry are widely regarded as unique to humans, and
associated with complementary functions such as a left-brain specialization for language …

Determining the intentionality of primate communication is critical to understanding the
evolution of human language. Although intentional signalling has been claimed for some …

Primates communicate with each other using a wide range of signals: olfactory signals to
mark territories, screams to recruit help while fighting, gestures to request food and facial …

Our goal in this chapter is to provide a concise introduction to the study of left–right
asymmetries in brain and behavior from a comparative perspective. We consider evidence …

Investigating in depth the mechanisms underlying human and non‐human primate
intentional communication systems (involving gestures, vocalisations, facial expressions …

Rodents and primates both show considerable variation in the overall size, the radial and
tangential dimensions, folding and subdivisions into distinct areas of their cerebral cortex …

We can learn about the evolution of neocortex in primates through comparative studies of
cortical organization in primates and those mammals that are the closest living relatives of …

Manual gestures and speech recruit a common neural network, involving Broca's area in the
left hemisphere. Such speech-gesture integration gave rise to theories on the critical role of …
