Oldest protein dating back to 3.8 mn yrs recovered
African scientists have extracted the oldest protein fragments encased in an ostrich eggshell dating 3.8 million-years-old. The proteins were preserved as they were "entrapped" in the surface minerals. Until now, the oldest sequenced protein was believed to have come from a 7,00,000-year-old horse. The find is believed to enhance future understanding of ancient organisms, including human beings.
