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.

AUSTIN, Texas — For centuries, the fate of the original Otomí inhabitants of Xaltocan, the capital of a pre-Aztec Mexican city-state, has remained unknown. Researchers have long wondered whether they assimilated with the Aztecs or abandoned the town altogether.According to new anthropological research from The University of Texas at Austin, Wichita State University and Washington State University, the answers may lie in DNA. Following this line of evidence, the researchers theorize that some original Otomies, possibly elite rulers, may have fled the town. Their exodus may have led to the reorganization of the original residents within Xaltocan, or to the influx of new residents, who may have intermarried with the Otomí population.Using ancient DNA (aDNA) sampling, Jaime Mata-Míguez, an anthropology graduate student and lead author of the study, tracked the biological comings and goings of the Otomí people following the incorporation of Xaltocan into the Aztec empire. The study, published in American Journal of Physical Anthropology, is the first to provide genetic evidence for the anthropological cold case....
