What Happens to Your DNA After You Die — It Doesn't Disappear

You're buried. Your heart stops. Your cells go dark. But your DNA? It's just getting started on the longest journey of its existence. In this video, we explore the hidden afterlife of DNA — from the enzymatic onslaught that begins minutes after death, to the astonishing discovery that readable genetic sequences can survive for over a million years inside permafrost-preserved teeth. Inspired by Richard Feynman's approach to building understanding from the ground up. 📚 SOURCES: Allentoft et al., "The half-life of DNA in bone: measuring decay kinetics in 158 dated fossils," Proceedings of the Royal Society B, 2012 van der Valk et al., "Million-year-old DNA sheds light on the genomic history of mammoths," Nature, 2021 Adler et al., "Survival and recovery of DNA from ancient teeth and bones," Journal of Archaeological Science, 2011 Rohland & Hofreiter, "Ancient DNA extraction from bones and teeth," Nature Protocols, 2007 Dabney & Meyer, "Extraction of highly degraded DNA from ancient bones and teeth," Ancient DNA: Methods and Protocols, Springer, 2019 Loreille et al., "DNA recovery and analysis from skeletal material in modern forensic contexts," Forensic Sciences Research, 2018 Peyrégne et al., "Ancient human DNA recovered from a Palaeolithic pendant," Nature, 2023 Taberlet et al., Environmental DNA: For Biodiversity Research and Monitoring, Oxford University Press, 2018 TIMESTAMPS: 0:00 — The moment your cells go dark 3:12 — Your own enzymes turn against you 7:45 — Why teeth outlast everything 12:30 — The 521-year half-life nobody expected 16:18 — DNA that leaks into the earth 20:40 — When bacteria steal the dead's genetic code 23:15 — A 20,000-year-old woman's necklace still holds her DNA 🎙️ AI-generated narration & visuals 📝 Script & research by the Feynman Reborn team ⚠️ WARNING: [This video is AI-generated (synthetic voice and visuals).
