Evolutionary linguistics (original) (raw)
Forschungsrichtung, die sich der biologischen Entstehung der Sprachfähigkeit sowie der geschichtlichen Entwicklung einzelner menschlicher Sprachen aus evolutionstheoretischer Perspektive nähert. English lemma 3 evolutionary linguistics definition in English 4 an approach to the study of human language based on evolutionary theory and attempting to account both for the emergence of the language faculty and for the historical development of specific human languages. further explanations examples 5 0. Basics Evolutionary Linguistics is inspired by the Theory of Evolution. Going back to CHARLES DARWIN, the theory explains the existence of different biological species and their inheritable traits. Its core is simple: many phenotypic and behavioural traits of organisms are encoded in their genes. When organisms reproduce, copies of those genes are passed on to their offspring, which consequently develop corresponding traits. Since errors ('mutations') occur in the process, populations are normally characterised by genetic, phenotypic, and behavioural variation. At the same time, the phenotypic and behavioural traits for which gene variants code may either increase or decrease the chances of an organism to survive and reproduce (i.e. its 'fitness'). Since environmental resources sustain only a limited number of organisms, evolutionary theory predicts that gene variants with a positive effect on the reproductive success of their carriers will outnumber and oust ('be naturally selected over') their less advantageous competitors. Since the effect which a genetically determined trait has on the reproductive success of its carrier depends on environmental conditions, evolutionary theory also explains why species tend to diversify and to adapt to the ecological niches they inhabit. Thus, it accounts for both the diversity of life and the fact that living organisms appear purposefully designed to maximise the reproductive success of their genes.
