In biology, abiogenesis (from Greek ἀ- a- 'not' + βῐ́ος bios 'life' + γένεσις genesis 'origin') or the origin of life is the natural process by which life has arisen from non-living matter, such as simple organic compounds. The prevailing scientific hypothesis is that the transition from non-living to living entities on Earth was ...And, taking the implication all the way, all of life must thus have one (or at most a few) common ancestor(s).

Then we can go on turning the clock yet further back, into the truly ancient "Planck epoch" – a period so early in the Universe's history that our best theories of physics break down. This era ...

The question of how life began is one of the most profound in science, and although many theories exist, scientists still cannot agree on an answer. It continues to be a topic for debate, as understanding life’s origin would help us grasp our place in the universe, as well as guiding our search for extraterrestrial life.How did life begin? What drove the transition, more than 3 billion years ago, from physical chemistry to biology (Pchem 2 Bio)? We seek the origins of biology’s forces of sustainability and persistent innovation. To be clear, this is not the same as seeking mechanisms of self-replication.Fundamental mysteries.
