    This dissertation examines the evolutionary impact of recent historical events on the population structure of the Rama Amerindians who inhabit the southern Caribbean coast of Nicaragua, by analyzing the mitochondrial DNA (mtDNA) polymorphic variants and their biological relationship with, and ancestral divergence from other neighboring groups. Genetic profiles of 265 individuals from seven Rama communities revealed that the majority of individuals belong to haplogroup B2 (71%) or A2 (28%), with the remaining 1% of variation comprised by the maternal lineages C1 and L3. Based on multivariate analyses combined with median-joining networks, AMOVA, tests of selective neutrality and diversity, phylogeography, and surname isonomy analyses, it is proposed that the geographic distribution of the haplogroups among the Rama communities reflects the history of migration of this population after the European incursion into the Caribbean region of Southern Central America following the 16th century. Ethnographic and ethnohistorical accounts of sub-population fissions and subsequent forced migrations are congruent with these results, leading to the conclusion that the disruption of the Rama's traditional way of life led to changes in mortality patterns, reproductive dynamics and epidemiology, which ultimately impacted the genetic variation of this population

    Linguistic Diversity: Empirical Perspectives

    Get PDF
    When comparing the more than 7000 human language varieties spoken today, one encounters a huge diversity in all domains of language, ranging from phonology via morphology up to syntax and pragmatics. In the seminar, we explored how language diversity can be studied empirically. In order to do so, we looked at linguistic approaches to the study of linguistic diversity from multiple perspectives, including classical approaches in historical and areal linguistics and linguistic typology, as well as recent, predominantly quantitative approaches in the field of diversity linguistics. In terms of topics, we focused on the major domains of language, such as phonology, morphology, and structure ("grammar" in a broad sense)

    Language Origins: From mythology to science, 226 s.

    The science of language evolution appeared at the end of the last century but top¬ically belongs to language origins – the domain of investigation that is concerned with the beginnings and diversification of language. Language evolution as a research area contrasts with the antiquity of language origins, which can be traced back to the earliest forms of traditional reflection. Language evolution emphasises its scientific orientation, whereas throughout most of its history language origins constituted a complex mixture of mythology, philosophy of language, as well as religiously and scientifically inspired speculation. This work is the first book-long attempt to document the whole history of language origins and situate language evolution in this wide intellectual context
