    Interesting example of adaptationist thinking in human biology. Hyp: menstruation is the byproduct of spontaneous decidualization of the endometrium, which evolved as a line of defense against invasive fetal tissues and/or for embryo selection. https://t.co/fOimY10fqh https://t.co/jGwYlhtyDl

    Menstruation evolved at least 3 times - primates, bats and the elephant shrew (more closely related to elephants & shrews!), possibly via genetic assimilation, to protect against aggressive embryos & for better embryo selection - interesting read!: https://t.co/dcTDyLCUL9 https://t.co/E88397ztcz

Abstract Synopsis

  • The paper explains that human menstruation likely evolved from a process called spontaneous decidualization (SD), which is a hormone-driven change in the uterine lining, as a result of maternal-fetal conflicts over pregnancy.
  • It proposes that SD originally evolved in nonmenstruating species as a fetal-induced reaction, but in humans, it became genetically fixed, allowing the body to prepare for pregnancy independently of fetal signals.
  • The authors present three models of how SD might have evolved through genetic assimilation, and suggest that understanding this process can help us better understand reproductive health issues like endometriosis and pregnancy loss.]
