The Future of Biotechnology: Revisiting the Spontaneous Generation of Living Organisms
Abstract: The emergence of life as a system of thermodynamically stable components capable of self-replication has been elucidated since Aristotle´s “Spontaneous Generation”. This chemical evolution begat primordial cells which then underwent evolutionary change, diversity and evolution stability at the ecological level; extinction for our planet is not foreseable in the near future. Life, single or pluri-cellular, can theoretically emerge from chemistry even nowadays but are less probable from the spontaneous assembly …
