Why Humans Invented Marriage

For most of human history, one question had no certain answer: Who is the father? Before DNA testing, written records, or modern medicine, humans had no reliable way to verify biological paternity. This documentary explores how anthropologists, evolutionary biologists, and historians believe that uncertainty may have influenced human relationships, family structures, and social institutions throughout history. Drawing on research in evolutionary biology, anthropology, archaeology, and psychology, this video examines the scientific evidence, competing theories, and ongoing debates surrounding paternity uncertainty and its possible impact on human behavior. Because human evolution spans millions of years and prehistoric societies left no written records, some topics discussed in this video are scientific hypotheses and interpretations rather than established historical fact. Where researchers disagree, multiple perspectives are acknowledged. This video is intended for educational and documentary purposes and encourages viewers to explore the scientific literature behind these fascinating questions.
