What is the widely accepted theory for the origin of life?

RNA World has been the prevailing theory for the origin of life since the 1980s. The emergence of a self-replicating catalytic molecule accounts for signature capabilities of living systems, but it doesn’t explain how the protobiological molecule itself arose.

What was John Needham’s experiment what was its result?
