Bayesian analysis of the astrobiological implications of life’s early emergence on Earth
- History, Physics
- Proceedings of the National Academy of Sciences
- 2011
Although terrestrial life's early emergence provides evidence that life might be abundant in the universe if early-Earth-like conditions are common, the evidence is inconclusive and indeed is consistent with an arbitrarily low intrinsic probability of abiogenesis for plausible uninformative priors.

It is shown that bolide impacts between about 3.6 and 4.0 billion years ago could have episodically melted an ice-covered early ocean and could have been important for the initiation of abiotic reactions that gave rise to the first living organisms. Expand
