| contents | <p>Current astrobiological models struggle to reconcile two distinct anomalies: (1) the rapid emergence of complex biological features on Earth (e.g., the Cambrian Explosion) and (2) the existence of "pre-adapted" traits in Earth organisms (e.g., radiotolerance in Deinococcus, vacuum survival in Tardigrades) that have no evolutionary precedent in Earth’s geological history. This paper proposes the "Galactic Repository Hypothesis": that Earth’s biosphere is not solely the product of local evolution, but a collection of genetic "legacy code" accumulated via lithopanspermia from diverse exoplanetary environments. We argue that this code, while dormant in Earth’s temperate environment, is retained in non-coding DNA regions ("Junk DNA"). Furthermore, we propose that the universal transport vector for this information is not DNA/RNA, but Peptide Nucleic Acid (PNA), due to its chemical robustness in interstellar space. Finally, we outline an experimental protocol, "Project Genesis," to test this hypothesis by transcoding Earth’s microbial metagenomes into PNA and deploying them to Venus, Mars, and Titan to trigger the reactivation of these ancestral, alien adaptations.</p> |
