To some extent, this reshaping resulted from changes in the sequence and/or the expression patterns of selected genes. Some of these genetic changes further facilitated cultural processes that have also played a major role in language evolution. In this chapter we review some of the key candidate genes for these changes, with a focus on our language-ready brain, our speech-ready organs, and our self-domestication. We discuss the shortcomings of present-day genetic approaches to language evolution and advance some avenues of future research.","PeriodicalId":410083,"journal":{"name":"The Oxford Handbook of Human Symbolic Evolution","volume":"30 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":"128349131","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}

However, these studies and the researchers faced intense criticism, which resulted in a vicious backlash that almost destroyed the field. In this chapter, the author will review the most frequent criticisms, any data-driven responses, and discuss the validity of each criticism. Ultimately, the findings show that nonhumans can acquire symbols through mechanisms more complex than simple association, that those symbols are referential in nature, they can use those symbols in appropriate contexts, and that their symbolic use is not explained by imitation. Some species have also been shown to use and/or comprehend rule-based ordering systems, but these stop short of true syntactical competence. Given the continuities revealed by these studies, any complete hypothesis regarding the evolution of language must incorporate these findings.","PeriodicalId":410083,"journal":{"name":"The Oxford Handbook of Human Symbolic Evolution","volume":"8 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":"127639380","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}

First, gesture and speech form a single system, with speech using a categorical format and gesture a mimetic format. Second, when this system is disrupted, as when speech is not possible, the manual modality takes over the categorical forms typical of speech. Finally, when the manual modality assumes a categorical format, as in sign languages of the Deaf, mimetic forms do not disappear but arise in the gestures signers produce as they sign. This picture of modern-day language is consistent with the view that gesture and speech have both been part of human language from the beginning.","PeriodicalId":410083,"journal":{"name":"The Oxford Handbook of Human Symbolic Evolution","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":"126903203","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}

If we accept a broadly gradualist account of evolution, forerunners of the symbolism found in human languages should be observable in our closest relatives. After intensive training by humans, animals as different as great apes, dogs, sea lions, parrots, and dolphins have been shown to be able to learn, and in some cases to use, linguistic symbols with both humans and conspecifics. However, there is an absence of convincing and widely accepted evidence for symbolism in the use by non-human animals of natural communication systems in the wild. In addressing this apparent paradox, we provide definitions of fundamental differences between human symbolism and non-human communication systems and discuss foundational capacities for symbolism in non-humans. We argue that animal signals sometimes thought to resemble symbols are more likely (as proposed by Darwin) emotional expressions. We offer arguments about the evolutionary pressures that may have led to increasingly complex communication in the hominin line.","PeriodicalId":410083,"journal":{"name":"The Oxford Handbook of Human Symbolic Evolution","volume":"37 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":"115922865","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}
