Hunt for the Oldest DNA

For decades, scientists have tried to unlock the secrets of ancient DNA. But life’s genetic blueprint is incredibly fragile, and researchers have struggled to find genetic material in fossils that has survived for millions of years. Then, one maverick scientist had the controversial idea of looking for DNA not in fossils or frozen ancient tissue – but in the soil.

This film follows the scientists deciphering the oldest DNA ever found and revealing for the first time the genes of long-extinct creatures that once thrived in warm, lush Arctic landscapes.
