Abstrakt

Proper theory for the origins-of-life should propose a logical chain of events that would start with prebiotic soup and end with a living organism. RNA-world seems to be the only theory for the origin-of-life that succeeds at this task. Despite heavy criticism directed at it no alternative theories of similar scope have been put forward.
This talk will be an attempt at providing an alternative theory for the origin-of-life based on the so called “compartmentalistic school” approach.
We will start by the premise of prebiotic-ecology, in which complex molecules of prebiotic soup interact with each other giving rise to supramolecular-selection, a process in which different macromolecular assemblies are preferentially formed basing on their contingent properties. The second premise will be a spontaneous appearance of autopoietic entities trough the actions of supramolecular selection. It will be argued that an emergence of hereditary evolution leading to life will conclude such a scenario.
Finally, this consideration will result in the proposition of new set of research directions that should be pursued by the origin-of-life scientists.
