• Oaxaca temple complex hints at archaic Mexican state

    Much of what we know about past civilizations in Mexico comes from the writings of colonial Europeans -- Spanish conquerors and priests -- who arrived in the Americas in the 1500s. But archaeological evidence from recent excavations at a site called El Palenque in the Valley of Oaxaca, Mexico, shows that temple precincts similar to the ones the Europeans encountered had existed in the region some 1,500 years earlier.Married archaeologists Elsa Redmond and Charles Spencer, both of the American Museum of Natural History in New York, reported the discoveries Monday in the journal Proceedings of the National Academy of Sciences.
