Using information theory, astrophysicist Edward Argyle calculated the probability that a single organism arose on the early Earth by chance. Argyle concluded: “It would seem impossible for the prebiotic Earth to have generated more than about 200 bits of information, an amount that falls short of the 6 million bits in E. coli by a factor of 30,000.”
