Two random numbers generated between 0-500 until they match.

Such is the explanation of the origin of life. Among the chemical combinations formed in the course of geological evolution under the influence of cosmic forces, some had the properties required for sustaining life. It was in this way that the simplest biological units started their existence. Life, which evolved into ever more complex structures, was nature's substitute for directly bred computers. Yet it was more than a substitute: it was a road—a winding road, yet one which despite all errors and hazards, crises and catastrophes, arrived at last at its destination.

—Olof Johannesson, The End of Man? (1966)
