By taking a new approach to examining human civilization, Prof. Sturt Manning, classics, and his team of undergraduate and graduate students from Cornell, the University of Toronto and the University of Cyprus, have uncovered new evidence that agricultural settlements had been formed up to half a millennium earlier than previously believed.

SAQQARA, Egypt (AP) — Archaeologists have discovered a new pyramid under the sands of Saqqara, an ancient burial site that has yielded a string of unearthed pyramids in recent years but remains largely unexplored.

The 4,300-year-old monument most likely belonged to the queen mother of the founder of Egypt's 6th Dynasty, and was built several hundred years after the famed Great Pyramids of Giza, antiquities chief Zahi Hawass told reporters in announcing the find Tuesday.

The discovery is part of the sprawling necropolis and burial site of the rulers of ancient Memphis, the capital of Egypt's Old Kingdom, about 12 miles south of Giza.

All that remains of the pyramid is a 16-foot-tall structure that had been buried under 65 feet of sand.
