Interesting Facts & Summary
Insights from Life's Time Capsules
- Chronological Span: From mammoths tens of thousands of years ago to microscopic organisms from hundreds of millions of years ago, sequencing brings history back to life.
- Core Technology: The 'Molecular Clock' is the essential technique for measuring mutation rates in these ancient organisms.
- Trivia: The oldest genetic data often comes from permafrost regions where cold temperatures slow down DNA degradation. These sequences are not just evolutionary specimens; they are treasures for modern medical research and foundations for 'de-extinction' theories.
