Vocal production learning, the ability to modify the structure of vocalizations as a result of
hearing those of others, has been studied extensively in birds but less attention has been …

An unresolved issue in comparative approaches to speech evolution is the apparent
absence of an intermediate vocal communication system between human speech and the …

ABSTRACT A critical feature of language is that the form of words need not bear any
perceptual similarity to their function–these relationships can be 'arbitrary'. The capacity to …

The study of non‐human animals, in particular primates, can provide essential insights into
language evolution. A critical element of language is vocal production learning, ie learning …

The extent to which vocal learning can be found in nonhuman primates is key to
reconstructing the evolution of speech. Regarding the adjustment of vocal output in relation …

Following the observation that vervet monkeys are capable of labelling different predator
types with their vocalizations, comparative research in language evolution gained …

The acoustic properties of vocalizations in common marmosets differ between populations.
These differences may be the result of social vocal learning, but they can also result from …

Once thought to be a unique human trait, the presence of culture in non-human primates has
been confirmed and studied by researchers for several decades. What has been discovered …

Trying to uncover the roots of human speech and language has been the premier motivation
to study the signalling behaviour of nonhuman primates for several decades. Focussing on …

Vocal learning, the ability to modify the acoustic structure of vocalizations based on social
experience, is a fundamental feature of speech in humans (Homo sapiens). While vocal …
