Genetic clues about the origin of Aché hunter-gatherers of Paraguay.

Seventeen genetic studies performed among the until recently hunter‐gatherer Aché were reviewed and the corresponding data integrated to general information about this group, and to statistical tests of hypothesis concerning its origin(s). Two features of the Aché gene pool emerge: (a) the distinctiveness in relation to the general pattern of Amerindian genetic data; and (b) the reduced within population genetic variability. As for the origin of this people, the evidence suggests a general Tupian background with considerable introgression of Jê genetic material, which could be explained by the Tupi warfare habit of absorption instead of extermination of defeated individuals.

A invenção do método: diplomacia como ética de pesquisa / The invention of the method: diplomacy as research ethics

This article arises from the question “How to invent a method?”, not toward the answer to this question, but rather to a discussion of the posture of the researcher in the exercise of building research methodologies. To this end, we aim to question those ways of doing research that are marked by a hierarchy between the researcher and its research object. As an alternative we bring
