Lifelines Beyond the Genome: Why Chickens Come Before Eggs

Abstract

Contrary to the prevailing view that life began on Earth with the emergence of so‐called self‐replicating molecules – DNA and RNA – it can be argued that cells, and mechanisms for generating cellular energy, must have been present before replication in the sense we now understand it could have arisen.

Keywords: cells; membranes; nucleic acids; autopoies; metabolic webs; abiotic synthesis
