In the study of the origin of life, evolutionary biology provides an important complement to prebiotic chemistry. The RNA world hypothesis, that modern DNA genomes and protein synthesis evolved from RNA-based precursors, has prompted efforts to reconstruct the RNA world by comparing contemporary RNA-based processes. We report recent results from large-scale comparative genomics screens aimed at gauging the extent to which intracellular RNAs can be traced back in evolution.
