BERLIN (AP) — Scientists say a previously unknown group of Stone Age farmers may have introduced agriculture to South Asia, challenging earlier theories that attributed the spread of farming to a different population. Scientists from Europe, the United States and Iran who examined the DNA of 9,000 to 10,000-year-old bone fragments discovered in a cave near Eslamabad, 600 kilometers (370 miles) southwest of the Iranian capital of Tehran, found they belonged to a man with black hair, brown eyes and dark skin. The Zagros people had very different genes than modern Europeans or their crop-planting ancestors in western Anatolia and Greece, said Burger, an anthropologist and population geneticist at Johannes Gutenberg University in Mainz, Germany.
