Chemical evolution in space — A source of prebiotic molecules

Advances in Space Research, 1983
In Laboratory Astrophysics at Leiden University a laboratory analog for following the chemical evolution of interstellar dust in space shows that the dust contains the bulk of organic material in the universe. We follow the photoprocessing of low temperature (10 K) mixtures of ices subjected to vacuum ultraviolet radiation in simulation of interstellar

Systems-chemistry approach to prebiotic evolution

, 2014
The puzzle of the origin of life is grand. A major challenge is to understand the transition from a mixture of molecules into an entity with basic life faculties, such as a protocell, capable of self-replication and inheritance. Two major schools tackle this problem: the genetic, or replicator-first approach, and the metabolism-first approach.
