Proteins from 'deep time' found in ostrich eggshell
Scientists have found preserved proteins in 3.8-million-year-old ostrich eggshells from Africa. The researchers say these biological building blocks - bound into the eggshell - could provide genetic information up to 50 times older than any DNA. These proteins, the team said, had been protected because they had been "entrapped" in surface minerals.
