- Origins and demographic dynamics of Tupí expansion: a genetic tale Eduardo José Melo dos Santos Andréa Luciana Soares da Silva Paloma Daguer Ewerton Louise Yukari Takeshita Maria Helena Thomaz Maia Antropología demographic Tupí homeland Patrilocality tupí expansion Genetic markers tupí linguistic groups display a wide geographical dispersion in south America, probably originated, as pointed by linguistic, from Madeira-Guaporé r egion (MGr) in Brazil. the present study reviewed genetic data on t upians for autosomal and uniparental (Y-chromosome and mtdnA) markers, using it to evaluate t upians geographic origin as well as the demographic dynamics of their dispersion from a genetic point of view. Comparison of genetic variability and mtdnA haplogroups d frequencies suggests a scenario where MGr is the t upí homeland. the relationship between five estimators of genetic variability (thetas-s, -Pi, -m2, -H and -k) shows that t upí groups from MGr and non-MGr experienced different patterns of demographic dynamics, with an ancient t upí expansion in MGr, followed by dispersion to other south America regions, probably associated to depopulation/founder effect events. f urthermore, other recent depopulation events could also be detected in both regions. f inally, the dispersion seems to be related to patrilocality, as suggested by comparison of uniparental markers genetic differentiation. this genetic model of dispersion dynamics may have an important impact in the interpretation of archeological and linguistic data, allowing to test if female associated technologies, like ceramic, are more extensively shared between dispersed populations than those which are not female-exclusive. 2015 artículo científico 1981-8122 https://www.redalyc.org/articulo.oa?id=394051442003 en http://www.redalyc.org/revista.oa?id=3940 Boletim do Museu Paraense Emílio Goeldi.
