As far back as 45,000 years ago, groups of hunter-gatherers lived in what is now called El Mirón Cave near the northern coast of Spain. First discovered for science in 1903 by local archaeologists and surveyed by University of New Mexico Professor of Anthropology Lawrence Straus in 1973, systematic excavation of the cave began in 1996 when Straus and Manuel González Morales of the University of Cantabria began their major ongoing research in the cave, leading to the discovery of prehistoric remains ranging from the time of the last Neanderthals through the Bronze Age.
