🧬 Fact: Around 8% of the human genome is made up of ancient viral DNA—remnants from retroviruses that infected our ancestors millions of years ago.
🔍 Why it’s wild: These viral “fossils” can sometimes still affect how your genes work, and some scientists believe they even played a role in the evolution of the human placenta!
