Any account of “what is special about the human brain”(Passingham 2008) must specify the
neural basis of our unique ability to produce speech and delineate how these remarkable …

Several hypotheses propose that cooperative breeding leads to increased cognitive
performance, in both nonhuman and human primates, but systematic evidence for such a …

Human cooperation is highly unusual. We live in large groups composed mostly of non-
relatives. Evolutionists have proposed a number of explanations for this pattern, including …

Vocal learning, where animals can modify the structure of their vocalizations as a result of
experience, has been found in a range of birds and mammals. Although vocal learning is a …

The Primate Origins of Human Nature (Volume 3 in The Foundations of Human Biology
series) blends several elements from evolutionary biology as applied to primate behavioral …

To understand the primate origins of the human interaction engine, it is worthwhile to focus
not only on great apes but also on callitrichid monkeys (marmosets and tamarins). Like …

The importance of auditory feedback in the development of spoken language in humans is
striking. Paradoxically, although auditory-feedback-dependent vocal plasticity has been …

The common marmoset (Callithrix jacchus), a highly vocal New World primate species, has
emerged in recent years as a promising animal model for studying brain mechanisms …

An increasingly popular animal model for studying the neural basis of social behavior,
cognition, and communication is the common marmoset (Callithrix jacchus). Interest in this …

Vocal communication is essential for social behaviors in humans and non-human primates.
While the frontal cortex is crucial to human speech production, its role in vocal production in …
