New dates rewrite Neanderthal story. Modern humans and Neanderthals co-existed in Europe 10 times longer than previously thought, a study suggests.
The most comprehensive dating of Neanderthal bones and tools ever carried out suggests that the two species lived side-by-side for up to 5,000 years. The new evidence suggests that the two groups may even have exchanged ideas and culture, say the researchers. The study has been published in the journal Nature. Until now, Neanderthal remains have been dated by a number of laboratories but many have been considered unreliable. Now an international team of researchers collected more than 400 samples from the most important sites in Europe. Ancient 'Evil Eye' Box Discovered In Nile River Cemetery. A 2,000-year-old cemetery with several underground tombs has been discovered near the Nile River in Sudan.
Archaeologists excavated several of the underground tombs, finding artifacts such as a silver ring, engraved with an image of a god, and a faience box, decorated with large eyes, which a researcher believes protected against the evil eye. Villagers discovered the cemetery accidently in 2002 while digging a ditch near the modern-day village of Dangeil, and archaeological excavations have been ongoing since then. The finds were reported recently in a new book. In the Sudan cemetery, researchers found a faience box decorated with large eyes that may have been meant to protect against the "evil eye.
