A sustained challenge to the dogma of female inferiority that applies evolutionary theory, comparative biology, and cross-cultural evidence to argue that the female organism often represents an advanced line of development. The work critiques scientific prejudices, surveys observed sexual dimorphism and purported male defects, and analyzes how social instincts and moral sensibilities evolved alongside sex differentiation. Drawing on ethnography and historical reconstruction, it traces prehistoric and early historic institutions, including gens, mother-right, marriage origins, and theories of wife capture, to show how male ascendancy emerged. The prose combines theoretical discussion with case studies to reassess assumptions about sex capacity and social consequences.
