Molecular de-extinction could offer avenues for drug discovery by reintroducing bioactive molecules that are no longer encoded by living organisms. Archaic human peptides display in vitro and in vivo antimicrobial activities with low host toxicity. Image credit: Ella Marushchenko. Human genomes and the genomes of our ancient ancestors express proteins with natural antimicrobial properties. Molecular de-extinction hypothesizes that these molecules...
