Questions remain, however, concerning whether the conditions that allow synthesis of these compounds in the laboratory accurately simulate those that might have been present on the early Earth, and a closer convergence between plausible prebiotic conditions and laboratory simulations remains a challenge for experimentalists.

Of the various scenarios that have been invoked for studying the origin of life, the ‘‘RNA first’’ model continues to be one of the most favored, due to the great explanatory power the hypothesis provides for understanding how Darwinian evolution might have begun.
Dissolved humic substances – ecological driving forces from the individual to the ecosystem level?
