The origin of life (OOL) took place around 4 billion years ago, soon after the Earth cooled in the Hadean Eon. Water-based chemistry converted small building blocks to large polymeric molecules. Polymers have incredible properties, including ability to form assemblies. Polymers can assemble into compartments, fibers, enzymes and motors and can store and transduce information.

We have models, that are testable by experiment, to explain how increasing complexity of polymers led to simple microbial cells. For nearly 3 billion years microbes ruled the planet. Complex plants and animals are relatively recent branches on the tree of life.

The OOL can be studied from the bottom up (using chemical principles) or from the top down (mining information from biological systems). In this presentation I will discuss progress from long-running efforts at Georgia Tech that use both top-down and bottom-up approaches to unravel the OOL.

Consideration of OOL forces us to frame and confront the most profound and vexing questions in science and philosophy. The OOL tests our understanding of geological, chemical and biological principles and unsettles our sense of place in the universe.
