Story summary

A groundbreaking study uncovers that nearly half of our genome is made up of transposable elements, once dismissed as "junk" DNA. Researchers from Japan, China, Canada, and the U.S. discovered that around 8% of our DNA comes from ancient viruses. This revelation could reshape our understanding of gene regulation, disease mechanisms, and human evolution.
