Ah, Sweet Mystery of Life, OSIRIS-REx May Find YouThe nature of the origin of life is a topic that has engaged people since ancient times. Where did we come from? What was the first life? How are we related? Are we alone? The study of biologic remains and environments preserved in rocks (fossils) and biochemical pathways and structures found across organisms (molecular fossils) can address these questions. Molecular evidence shows that all life on Earth is related fundamentally, biology shares a genetic language, related molecular machinery, and common chemistry By looking at the details of genetic and protein sequences more detailed relationships can be determined for modern organisms.
