Using oxygen stable isotope analysis of tooth enamel from animals butchered by humans at the site of Bacho Kiro Cave, Bulgaria, Max Planck researchers show that human groups belonging to an early wave of dispersal of our species into Europe were faced with very cold climatic conditions while they occupied the cave between about 46,000 and 43,000 years ago. Archaeological remains at Bacho Kiro Cave currently represent the oldest known remnants of Upper Palaeolithic Homo sapiens in Europe, and thus open a unique window into the time when our species started to move out of the Levant and establish itself across the mid latitudes of Eurasia as part of an archaeological phenomenon called the Initial Upper Palaeolithic.

Early Maya cities featured monumental complexes, which centered on a shared form of religion but these complexes transformed radically once kingship emerged in 400 B.C.
