How scientists are tracing Earth’s first complex life
Key Takeaways
- Researchers say the earliest eukaryotes were a foundational step toward complex life on Earth.
- The fossil record is sparse because organisms older than 500 million years lacked shells and skeletons.
- Scientists are pairing fossil searches with rock chemistry to identify environments that preserved ancient cellular remains.
- The work also informs how astrobiologists think about detecting complex life beyond Earth.
