Muttertier - Muttermensch(1999)

Lucy, who is already human-like, claims that the first humans were mothers: The mother built a nest to secure the child when it became too heavy to carry. This is how she invented the house. She penetrated the dense branches with her voice to maintain contact with the child. That's how she invented language. Today, Lucy shakes her head and asks: "How did you let yourself be dragged down like that?".
