Following the analysis of those data, we additional traced the transmission network of yalewa vuku (smart ladies), who had been identified as a vital supply of food taboos. We asked every single person over age 7 in two neighbouring villages who they look at to become a yalewa vuku. Additionally, information on perceived knowledge had been gathered in a separate interview (performed in the course of a prior field season) by asking absolutely everyone over age six to list people who know by far the most about medicinal plants (standard medicine and regional treatments). See the electronic supplementary material for facts. (i) Results and of selective cultural mastering Participants’ responses to the question of how they acquired their meals taboos have been categorized as shown in figure two (some gave two responses). The results indicate two critical functions of these taboos. First, our final results recommend that these are principally culturally transmitted, and not acquired by direct encounter nor evoked by environmental circumstances. Significantly less than five per cent of females pointed out finding out anything from direct expertise or observation, and all these people who mentionedJ. Henrich N.

Second, the patterns of transmission are consistent together with the modelbased studying mechanisms described above, when the evolving technique is near equilibrium. Figure two shows that most girls discovered from their mothers, grandmothers or mothersinlaw, as these models are commonly low price, accessible and share fitness incentives together with the learner. Having said that, nearly a quarter of girls reported studying from yalewa vuku (wise women) and virtually a third reported finding out from qase (elders, commonly referring to senior noncloserelatives). Yalewa vuku are women who are nicely respected and thought of knowledgeable about standard medicine, birthing and child care, also as other skills traditionally considered the province of females. It truly is a recognized, although informal and emergent, social role. By selectively attending to such preferred models, learners can strengthen 
on cultural variants acquired from their household members. Modelling efforts recommend that, over generations, this tendency can stabilize a population at an adaptive equilibrium (Henrich 2004).six To study the pathways of transmission from yalewa vuku, we asked men and women to name the yalewa vuku. Every single respondent spontaneously named in between zero and 5 men and women. The network in figure three illustrates that there is certainly substantial agreement on who the yalewa vuku are (i.e. the network is centralized) and that a handful of individuals possess a disproportionate influence on cultural evolution. Only six people were nominated ( were under no circumstances nominated). Of these, only 25 people received greater than five nominations and only three received more than.
