In a recent paper in Nature Communications, collaborator Gonen Ashkenasy and co-workers report on their continued investigations related to the origin of life, analyzing a complex web of reactions in β-sheet peptide networks, and focusing on the formation of specific intermediate compounds and template-assisted replication. Specifically, they show that the enrichment of one ‘‘master sequence’’ is a result of a collective network behavior manifested by multiple template-assisted processes. They suggest that their findings may shed light on molecular evolution processes that led to current biology.
