Not sure I agree with mitochondria, though of course they are very important to life. If we are talking origin of life I would say "membrane" which also begins with m. It's the cell membrane that allowed early life to separate itself from its environment and maintain homeostasis.
btw...mitochondria were originally free living organisms that became "captured" inside early cells through the process of endosymbiosis. And to make a connection back to astronomy... this theory was first proposed by Lynn Margulis the first wife of Carl Sagan!
Thanks for the challenge...the simplest questions are the most thought provoking.
