Resposta ao trabalho de Kent e Santos: "'Os charruas vivem' nos Gaúchos: a vida social de uma pesquisa de 'resgate' genético de uma etnia indígena extinta no Sul do Brasil"

human actions, including scientific research, are structured in individual and collective contexts. kent and santos's paper considered that in a particular scenario, but when they consider this fact they also give opportunity to interpretive actions. the most important is that the authors draw attention to emerging areas of the biological sciences, whose results could not only assist in understanding the dynamics involved in "doing science", but also as how human actions may be far from being understood only within a cultural-reductionist context. in this way, the authors introduce more elements to the debate on the need to persist, and the legitimacy of the barriers that separate biological anthropology, in which human genetics is inserted, and sociocultural anthropology.
