I am an environmental historian who focuses on the United States but I often teach World History surveys and I am at a loss when students ask about the emergence of patriarchy. Every text I have used in my world history courses discusses the general equality between sexes that most hunter-gather societies enjoyed but they never fully explain the transition toward patriarchal communities especially after the Neolithic Revolution. I've have done some additional research and read Barbara Smuts' work on The Evolutionary Origins of Patriarchy and Sebastian Kramer's argument that ties the emergence of patriarchy to the concept of fatherhood. Both of these studies are now decades old and I do not have any familiarity with the literature so I don't know how they were received by other historians. Unfortunately, the FAQ on the sidebar contains very little about this question. I really want to know more so I feel more confident discussing this topic in my courses.
