In this paper we develop models to explore whether extortion or deception is the more plausible origin of the melodrama in a baby's cry. According to these models, deception seems a more plausible origin than extortion because extortion requires the incoherent assumption that nature can select against the genetic interests of an organism. By comparison, the assumptions required to rationalize a deception explanation — that the parent share in the benefits given to its offspring — seem relatively harmless and consistent with contemporary sociobiological theory.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133175488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is considerable interest in the degree to which bird, ground-dwelling sciurid rodent, and primate alarm calls denote the species or type of predator that elicited the vocalization. When there is a tight association between the type or species of predator eliciting an alarm call, and when a played-back alarm call elicits antipredator responses qualitatively similar to those seen when individuals personally encounter a predator, the alarm calls are said to be functionally referential. In this essay I aim to make two simple points about the evolution of functionally referential alarm communication. Firstly, functionally referential communication is likely to be present only when a species produces acoustically distinct alarm vocalizations. Thus, to understand its evolution we must study factors that influence the evolution of alarm call repertoire size. Secondly, and potentially decoupled from the ability to produce acoustically distinctive alarm vocalizations, species must have the perceptual and motor abilities to respond differently to acoustically-distinct alarm vocalizations. Thus, to understand the evolution of functionally referential communication we also must study factors that influence the evolution of context-independent perception. While some factors may select for functionally referential alarm communication, constraints on production or perception may prevent its evolution.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years the debate has been dominated by those who believe that grammar consists of rigid, categorical rules and structures of such a remove from the spoken language that children could not learn them from the input available in the environment (Pinker and Bloom 1990; Chomsky 1975). Led by Chomsky, linguists at MIT, and those associated with them, have accepted the view that abstract grammatical principles are lodged in an innate Language Acquisition Device, a module of the mind that supplies the child with the basic principles of grammar. This device, containing as it does, all the principles of Universal Grammar, is meant to explain how children acquire their language rapidly and without formal instruction, and in addition, it is meant to encapsulate the core features that all languages have in common (Bickerton 1981; Chomsky 1965; Pinker 1994). In this view, grammar is highly abstract knowledge which is autonomous and not reducible to concepts outside the system (Newmeyer 1990). This means that grammar does not relate directly to meaning or function or indeed to the uses to which language is put, but rather it constitutes a purely abstract system. Possession of this innate system makes language acquisition possible for homo sapiens, while the lack of such a device precludes language acquisition by our close relatives in the great ape family. Given this theory of grammar, the question for evolution is how such a specialized device could have evolved, since as far as we know, none of our","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131901376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We claim that phonological systems could have emerged as the product of self-organizing processes. Self-organization may have facilitated the evolution of structures within the sounds that humans were able to produce. One of the main points of the paper concerns the identification of the processes which could account for the self-organized behavior of sound systems used in languages spoken by humans. In this paradigm, phonological systems or sound patterns of human languages are emergent properties of these systems rather than properties imposed by some external influence. Regulations are defined as the constraints that adjust the rate of production of the elements of a system to the state of the system and of relevant environmental variables. The main operators of these adjustments are feedback loops. Two types of processes can be distinguished in regulatory networks, homeostatic and epigenetic. Since the origin of sound patterns, of human languages, is in the vocal tract constraints, we make the hypothesis that sound change does not reflect any adaptive character but rather is the phonetic modality of differentiation understood as epigenetic regulation.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134471359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been observed that human vowel systems show remarkable regularities, and that these regularities optimise acoustic distinctiveness and are therefore adaptive for good communication. Traditionally, universals have been explained as the result of innate properties of the human language faculty, and therefore need an evolutionary explanation. In this paper it is argued that the regularities emerge as the result of self-organisation in a population and therefore need not be the result of biological evolution.The hypothesis is investigated with two different computer simulations that are based on a population of agents that try to imitate each other as well as possible. Each agent can produce and perceive vowels in a human-like way and stores vowels as articulatory and acoustic prototypes. The aim of the agents is to imitate each other as well as possible.It will be shown that successful repertoires of vowels emerge that show the same regularities as human vowel systems.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125946464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These authors claimed that the acquisition of a low laryngeal position during evolution is a necessary condition for having a vowel space large enough to realize the necessary vocalic contrasts for speech. Moreover, Neandertals didn't posses this anatomical base and therefore could not speak, presumably causing their extinction. In this study, we refute Lieberman and Crelin's theory by showing, first with the analysis of biometric data, that the estimated laryngeal position for two Neandertals is relatively high, but not as high as claimed by the two authors. In fact, the length ratio of the pharyngeal cavity to the oral cavity, i.e., an acoustically important parameter, of the Neandertals corresponds to that of a modern female adult or of a child. Second, using an anthropomorphic articulatory model, the potentially maximum vowel space estimated by varying the model morphology from a newborn, a child, a female adult and to a male adult didn't show any relevant variation. We infer then that a Neandertal could have a vowel space no smaller than that of a modern human. Our study is strictly limited to the morphological aspects of the vocal tract. We, therefore, cannot offer any definitive answer to the question whether Neandertals actually spoke or not. But we feel safe saying that Neandertals were not morphologically handicapped for speech.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134215500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For one group the observations represent a fourth longitudinal time point over a 12 year period; the other group was observed for the first time. There were two main questions. The first concerned how young chimpanzees use their gestures, with special foci on the flexibility displayed in signal use and on the sensitivity to audience displayed in signal choice. It was found that chimpanzees are very flexible in their signal use (different signals for same goal, same signal for different goals) and somewhat sensitive to audience (signal choice based on attentional state of recipient). The second question was how chimpanzees acquire their gestural signals. Comparisons between the two groups showed much individual variability both within and between groups. In addition, when each of the two contemporary groups was compared with the previous longitudinal time points for one of the groups, no differences in concordance were found. It was concluded that youngsters were not imitatively learning their communicatory gestures from conspecifics, but rather that they were individually ritualizing them with one another in social interaction. An experimental study in which two individuals were taught new gestures and returned to their groups — with no subsequent signs of imitation — corroborated this conclusion. Implications of the current findings for the understanding of chimpanzee communication and social learning are discussed.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132816002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We suggest that: 1) Highly social subterranean rodents that do not leave their burrows use essentially vocal signals in the vibrational channel; 2) Solitary and almost permanently fossorial species use vocal signals in short range and seismic signals in long range communication; 3) Other solitary species that leave the burrow system more frequently and that retain good visual capabilities are constrained to use vocal communication only. Also we suggest that seismic communication probably derives from digging activities and, consequently, developed after the acquisition of the subterranean way of life. The first three statements are based on a previously proposed relationship between visual capabilities, hearing capabilities, time spent outside the burrows, social organization and type of vibrational signals used by the species. The fourth statement is based in the correlation found between digging and transporting tools and thumping tools, that are the same across the literature on pertinent genera. Some thumping techniques unique to subterranean animals lead us to propose an evolutionary sequence leading from digging to thumping.","PeriodicalId":348718,"journal":{"name":"Evolution of Communication","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129704260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
