The discovery of viruses that could cause cancer (like Rous Sarcoma Virus) provided the first clear, reproducible experimental model showing that an external agent could transform normal cells into cancer cells. This shifted the paradigm and led directly to the discovery of the first oncogenes (e.g., src), revealing that cancer-causing genes could be captured from viruses and were originally derived from normal host cell genomes.
