evidence used to study the evolution of language

(1985). Possible and probable languages: A generative perspective on linguistic typology. The mentality of crows: Convergent evolution of intelligence in corvids and apes. Other commentators find even this idea dubious (Boë, Heim, Honda, & Maeda, 2002; de Boer, 2010; Fitch, 2010; Nishimura et al., 2006), in part because nonlinguistic functions for changes such as a descended larynx are now known from nonhuman species (Fitch & Reby, 2001). ten Cate, C. (2016). Language as shaped by the brain. Human language is a culturally evolving system. Liem, K. F. (1990). Despite this, hand-axe technology remained essentially the same for about one million years, strongly suggesting that Homo erectus/ergaster did not have the full cognitive and cultural capabilities of modern humans, and by inference did not have full modern human language. Laland, K. N. (2017). Poeppel, D., Emmorey, K., Hickok, G., & Pylkkänen, L. (2012). Proceedings of the National Academy of Sciences, 99(20), 13206–13210. A., Bassan, A. I., Capellini, T. D., Guenther, C., … Kingsley, D. M. (2011). There are essentially three time scales at which genomic data are applicable. Tattersall, I. In reporting on observational research, language here is crucial, because the audience may not be familiar enough with epidemiologic evidence and study design to appreciate the nuances. Gathering evidence to study mass extinctions. The driving force for this key innovation, which added explicit semantics to a preexisting mimetic communication system, was sharing detailed propositional information with close kin, especially between parents and their offspring (this was thus a “mother tongue,” driven by kin selection to raise inclusive fitness; Fitch, 2004), with close similarities to what Kevin Laland terms “teaching” (Laland, 2016, 2017). Cognitive ornithology: The evolution of avian intelligence. Loss of function of a particular protein led to inactivation of a muscle protein expressed particularly in the temporalis jaw muscle, MYH16, and may have led to the reduction in this muscle’s size and jaw robusticity (Stedman et al., 2004). This is why I treat this as a single DCL, although future research may cleave this complex into biologically separate components. Pylkkänen, L., & Marantz, A. Join our community of educators and receive the latest information on National Geographic's resources for you and your students. Cerebral Cortex, 23(8), 1859–1873. This is the major problem faced by musical protolanguage theories, and there can be little doubt that both the mimetic potential of gesture and the onomatopoetic nature of sound helped pave the way for this key innovation (Blasi et al., 2016). Body mass and encephalization in Pleistocene Homo. There is broad agreement about the importance of such pragmatic interpretation in language (cf. (In this issue). In C. Lyon, C. Nehaniv, & A. Cangelosi (Eds. The clearest evidence from the fossil record concerns the timing of bipedalism, large body size, and large brains. Orr, W. F., & Cappannari, S. C. (1964). The fate of the Neanderthals. (2003). Chicago, IL: University of Chicago Press. Bemis, D. K., & Pylkkänen, L. (2012). Human cortical motor representation of the larynx as assessed by transcranial magnetic stimulation (TMS). Quaternary International, 295, 94–101. These data are often generated by researchers who have no particular interest in language evolution per se, but see themselves rather as broadly studying cognitive neuroscience, paleo-genomics, brain evolution, theoretical linguistics, or human (cultural) evolution. Evolutionary sleight of hand: Then, they saw it; now we don’t. Vision and art: The biology of seeing. Nature, 432(7016), 461–465. The origins of complex language. (2010). From animals to humans? Darwin was an extreme gradualist, believing that only the accumulation of small successive variants could lead to adaptation, but he was criticized for this viewpoint by many contemporaries (Eldredge & Gould, 1972; Gould, 1982; Theissen, 2009), and the belief that “Darwinism = gradualism” was one reason that many early geneticists opposed Darwinism (e.g., Bateson, 1894). Jackendoff, R., & Wittenberg, E. (2016). In A. Wray (Ed. (2013). Evolution of forebrain and spatial cognition in vertebrates: Conservation across diversity. (1989). But the critical point illustrated by the fact that Neanderthals, unlike chimpanzees, shared our version of FOXP2 is that paleo-DNA allows us in principle to test specific evolutionary hypotheses and address long-standing debates in a way that, only a decade ago, would have been unthinkable. Nowicki, S., & Searcy, W. A. Language-tree divergence times support the Anatolian theory of Indo-European origin. Liem, K. F. (1973). London, UK: Thames & Hudson. The reasons are simple: We have whole new classes of data that provide new insights into key issues and problems (e.g., paleo-DNA). Nature Communications, 10506. doi:10.1038/ncomms10506. Genes, language, cognition, and culture: Towards productive inquiry. 3. 195–212). Such data have provided a reasonably clear picture of what language is and how it is acquired during infancy and childhood. A hominid from the lower Pleistocene of Atapuerca, Spain: Possible ancestor to Neandertals and modern humans. European Journal of Human Genetics, 1(1), 3–18. Psychonomic Bulletin & Review. Concepts such as adaptation and mutation inform therapies and strategies to combat pathogens, including influenza. This is evidence of “call usage learning” but not vocal production learning. doi:10.3758/s13423-016-1074-x. The process of evolution. Byrne, R. W., & Cochet, H. (2016). Mapping the origins and expansion of the first Indo-Europeans. Maynard Smith, J., & Haigh, J. The essential idea is that hominins first developed a word-based protolanguage that was learned, symbolic, and useful, and only later evolved a capacity for hierarchical syntax. The current leading hypothesis for the mechanisms underlying the increased vocal control necessary for vocal production learning is that such control requires direct synaptic connections from motor cortical regions (or its equivalent, area RA, in songbirds) onto the motor neurons controlling the larynx (or syrinx in birds; Deacon, 1992; Jarvis, 2004a; Jürgens, 2002; Kuypers, 1958; Ploog, 1988; Simonyan, 2014; Striedter, 2004). In A. M. Di Sciullo & C. Boeckx (Eds. doi:10.3758/s13423-016-1157-8. Perhaps the most noteworthy early result of this paleo-DNA work is the finding that Neanderthals (and Denisovans) shared with us the modern derived variant of the FOXP2 gene, indicating (contra the original predictions of Enard et al., 2002, based on selective-sweep methods) that the modern variant evolved and was fixed at least 500 KYA, before the split between us and Neanderthals. First, I do not posit any “one word” stage of language evolution: Protolanguages always involved sequences, and words were “condensed out” of holistic utterances by learners, rather than first appearing as isolated building blocks to be put together later. The roles of the external, middle, and inner ears in determining the bandwidth of hearing. Evidence for Evolution. Part of Springer Nature. Pepperberg, I. M. (2005). Evolutionary developmental biology and human language evolution: Constraints on adaptation. Like hearing, the anatomy of the primate vocal tract was essentially “speech ready” whenever the neural control and cognitive capabilities evolved, as concluded long ago by both Darwin and Negus (Darwin, 1871; Negus, 1938). In a 1866 paper titled “On the origin of language,” he attempted to support the “bow- wow theory” by invoking the ways in which “savages” in the colonies named the Europeans and.
