The Population Structure of an Amerindian Tribe, the Yanomama

“…The documentary fi lms of Chagnon, Asch, and Neel can also be consulted by anyone seeking a more graphic introduction to the culture. 4 Physically, the Yanomama are relatively short and slender (3,11,12). Although there is great physical variability among the Yanomama, we are unable to confi rm the suggestion of Vinci [1956, quoted in (6)] and Zerries (6) that there are four distinct physical types of Yanomama.…”

“…The fi rst signifi cant anthropological studies were undertaken by Zerrles and Becher in the early 1950s [see especially (3)(4)(5)(6)]. From the fragmentary data available, it seems clear that the Yanomama have in the last century expanded-their tribal area, more or less centrifu gally, by a factor of two or perhaps three, as shown in Figure 1.…”

A cross-cultural analysis of the behavior of women and men: Implications for the origins of sex differences.

“…Also relevant to the claim that men's desire to control women's sexuality to assure paternity is an evolved disposition is evidence that women's extramarital sex not only is widespread in world societies but also is often legitimized within the social structure (Broude & Greene, 1976; Hrdy, 2000; Whyte, 1978). For example, in some societies extramarital sexual relations take the form of socially sanctioned wife sharing, in which wives have sexual intercourse with the husband's male relatives or even with his friends and allies (e.g., Becher, 1960; Elam, 1973; Weltfish, 1965). In Broude and Green's (1976) study, 35% of 110 nonindustrial societies represented with sufficient information were classified as allowing wife sharing under at least some circumstances.…”

The genetic structure of a tribal population, the Yanomama Indians V. Comparisons of a series of genetic networks*,†

“…The Yanomama, who probably comprise one of the largest and certainly one of the least acculturated tribal populations in South America, have been fairly extensively described in the ethnographic literature (Becher, 1960; Zerries, 1964; Chagnon, 1 9 6 8~) .…”

“…While this paper utilizes a geographical classification, there is a degree of correspondence between these five groupings and groups formed on the basis of other variables, e.g. linguistic (Wilbert, 1963;Migliazza (personal communication), 1967), ethnographic (Becher, 1960;Chagnon, 1966Chagnon, , 1967 and anthropometric (Diaz-Ungria, 1956;Vinci, 1959). While one of the aims of this paper is to ascertain whether groups defined on a geographical basis are genetically distinct, later papers will explore the relationship between such groups and groupings formed on the basis of linguistic and anthropometric data.…”
