  2. raoscaos said: “If you knew anything about human development” is a bold opener for a claim that ignores basic evolutionary biology. Baby, menstruation is not a historical or cultural invention. It’s an evolved reproductive trait that predates human civilization by millions of years and occurs in other mammals, including primates (apes and Old World monkeys), certain bats, and species like elephant shrews. If you’re genuinely interested in evidence-based research, I recommend starting with Beverly Strassmann’s peer-reviewed article “The evolution of endometrial cycles and menstruation” (1996), published in The Quarterly Review of Biology.
