The placenta is essential for life, but so much of its function is unknown. In this episode, we talk about how this disposable organ’s development within the early weeks of pregnancy shapes so much of what happens months later. We tackle what makes the human placenta so unique, what other animals like reptiles are teaching us about it, and how scientists are turning to evolution and computer models to see if we can better understand it.
