Symbols are not uniquely human
Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human. Here we show that alarm-calls such as those used by African vervet monkeys (Cercopithecus aethiops), logically satisfy the semiotic definition of symbol. We also show that the acquis...
متن کاملLong-distance Dependencies Are Not Uniquely Human
It is widely assumed that long-distance dependencies between elements are a unique feature of human language. Here we review recent evidence of long-distance correlations in sequences produced by non-human species and discuss two evolutionary scenarios for the evolution of human language in the light of these findings. Though applying their methodological framework, we conclude that some of Hau...
متن کاملClosure spaces that are not uniquely generated
Because antimatroid closure spaces satisfy the anti-exchange axiom, it is easy to show that they are uniquely generated. That is, the minimal set of elements determining a closed set is unique. A prime example is a discrete geometry in Euclidean space where closed sets are uniquely generated by their extreme points. But, many of the geometries arising in computer science, e.g. the world wide we...
متن کاملThe descended larynx is not uniquely human.
Morphological modifications of vocal anatomy are widespread among vertebrates, and the investigation of the physiological mechanisms and adaptive functions of such variants is an important focus of research into the evolution of communication. The "descended larynx" of adult humans has traditionally been considered unique to our species, representing an adaptation for articulate speech, and deb...
متن کاملWhat Are the Uniquely Human Components of the Language Faculty ?
9.1 Introduction From a biologist's perspective, language has its own particular design features. It is present in virtually all humans, appears to be mediated by dedicated neural circuitry, exhibits a characteristic pattern of development, and is grounded in a suite of constraints that can be characterized by formal parameters. Th us, language has all the earmarks of an adaptation, suggesting ...
