R_1_07 — Viruses as Evolutionary Drivers — Endogenous Retroviruses and Genomic Integration
Viruses are not merely disease agents — they are fundamental architects of evolution. The human genome contains approximately ~8% endogenous retroviral (ERV) sequences (~100,000 ERV fragments), meaning roughly eight time
