Final answer:
Yanomamo women are primarily involved in gathering activities, such as harvesting bananas and cassava, a practice which forms part of a broader pattern of sexual division of labor in traditional societies.
Step-by-step explanation:
The Yanomamo women generally participate in gathering subsistence activities such as gathering bananas and cultivating the cassava. In various traditional societies, such as Hadza, Kayapó, and Baka, the economic roles divided along gender lines constitute what anthropologists call a sexual division of labor. While this division of labor tends to be flexible with overlaps, it is observed that women commonly engage in gathering activities. They gather tubers, berries, greens, and also participate in the farming of staple crops, which includes harvesting and processing cassava, among other carbohydrates. Gathering is crucial as it frequently contributes the majority of calories to their diets compared to the meat obtained from hunting.
