What Were the Chances of Abiogenesis?

Life arose early in Earth’s history. Was this an inevitable process, or an extremely unlikely event that happened early on, and what does this tell us about the likelihood of life on other worlds? In a new paper, a researcher calculated the variables that went into the formation of life and found that a spontaneous emergence is theoretically feasible, but extremely unlikely. Instead, he suggests that there could be protection mechanisms or unknown self-organising principles that got life going.
