  We can see situated knowledge in Jeanne Altmann's working from the perspective of a woman, a mother, and a feminist to develop methodologies that allowed for the systematic study of the often low-drama interactions among female primates and between mothers and their offspring, which were previously not salient to researchers. Another example from Primate Visions (1989) is Adrienne Zihlman's critique of associations of sexual dimorphism with, usually male, dominance. Zihlman, who is best known for her development, with Nancy Tanner, of Woman the Gatherer theory of early human evolution, consciously developed a feminist stance toward gender and science. Zihlman argued that sexual dimorphism was not a unitary phenomenon. Different species can be sexually dimorphic not only to different degrees, but in different ways, including bone length and structure, tendencies to build muscle or fat tissue, and/or canine size. These different kinds of sexual dimorphism can be related to differences in aggressive capacities and differences in foraging strategies, both of which had been associated with evolutionary accounts of gender differences. Zihlman's stance as a feminist scientist allowed her to focus on heterogeneity and complexity, which made generalizations about sexual dimorphism highly problematic and undermined associations of general sexual dimorphism with male dominance.
