The question of the origin of life was probably asked as soon as humans developed self-consciousness. Our ancestors realized very early that plants, animals, and humans, are distinct from non-living entities on Earth such as rocks, water, and air. Where did life come from?

Primitive life – defined as a chemical system capable of transfering its molecular information via self-replication and also capable of evolving – probably originated about 4 billion years ago from the processing of organic molecules by liquid water. Organic matter might have been formed in the primitive atmosphere from methane or carbon dioxide but ...

A formal solution of the main problems concerning the origination of life is attempted, adopting as fundamental axiom the plausible assumption that it was a spontaneous, natural sequence of "most probable" events. Survival by natural selection is a particular example of a most probable event, and therefore operated at all stages of the origination ...

It is beyond denying that life has become the focal point of presentday philosophical investigation. And the question of life’s origins, in particular, once dismissed by philosophers as meaningless, is becoming the focal point of interest for science, one hiding a cluster of issues around which all scientific investigation turns, and on which they ...
