AbstractThis thesis, in the form of a literature review, surveys the body of knowledge pertaining to the human placenta. It begins with an introduction to placental morphology and human placental evolution in a comparative anatomy context, demonstrating the special role of placental invasiveness in humans. Next, discussions of parent-offspring conflict, parent-of-origin imprinting, life history theory, and plasticity explore the adaptive value of human placental morphology and function. The thesis concludes with an overview of obstetric disorders and their relationship to the trajectory of human placental evolution. I emphasize the importance of the parent-offspring conflict in understanding the evolution of human placental physiology and variation, as well as resultant obstetric disorders.
