My Ancestors Were One-Celled Organisms.

Abstract

This first-person essay explores wonder in the medical encounter from a patient's point of view, considering times when medical technology has given the author insight into her body and the wonder that has been evoked by these experiences. Two medical encounters are detailed: one in which post-polio vocal cord weakness was explored using a miniature camera, which evoked a sense of wonder at the process of evolution; and the second in which an MRI of the author's skull became a memento mori. The author reflects on the long processes of genetic mutation from single-celled organism to human being, and on the devolution after death to food for bacteria and insects.
