Evolution is a theory about the origins of life.


Although certainly contiguous with evolution, research into life’s origins is not usually considered evolutionary research.

It’s an active and quite contentious field, one full of open questions and competing hypotheses. Did life emerge as a simple system in a complex environment or as a complex system in a simple environment? Was replication first or was metabolism first? Were cells latecomers or early arrivals? Did it happen in a warm little pond or at a hydrothermal vent or on a different planet altogether? To a scientist or science enthusiast, these types of questions are exactly what make origins-of-life research so fascinating.
