Abstract(s)

Darwin’s allegorical “warm little pond” was most probably located outside the Earth and Darwinian evolution, including genetic transfers occurred over a vast galactic scale. How did life arise? Not just on the Earth, but anywhere in the Universe? Does life emerge readily on every Earth-like planet by spontaneous processes involving well attested laws of physics and chemistry, or did it involve an extraordinary, even miraculous intervention? Science must necessarily exclude a miraculous option of course, but the other questions continue to be asked.
