More evidence against a “metabolism first” origin of life
New research by Universitat Autònoma de Barcelona, published in the Proceedings of National Academy of Sciences, has revealed problems with origin of life hypotheses that are based on metabolic systems developing first, as opposed to an RNA or DNA system.
The researchers found that compound genomes, or “composomes”, the basic unit of proto-life in metabolism-based hypotheses, are unable to undergo Darwinian evolution, putting serious doubt onto thoughts that they could foster the beginning of life on planet Earth.
However, this is just one study – more research needs to be done to confirm or deny these results.
