Two speleothem stable isotope records from East-Central Europe demonstrate that Greenland Stadial 12 (GS12) and GS10-at 44.3-43.3 and 40.

Cueva de los Aviones (southeast Spain) is a site of the Neandertal-associated Middle Paleolithic of Europe. It has yielded ochred and perforated marine shells, red and yellow colorants, and shell containers that feature residues of complex pigmentatious mixtures. Similar finds from the Middle Stone Age of South Africa have been widely accepted as archaeological proxies for symbolic behavior.

The Middle Pleistocene is a crucial time period for studying human evolution in Europe, because it marks the appearance of both fossil hominins ancestral to the later Neandertals and the Acheulean technology. Nevertheless, European sites containing well-dated human remains associated with an Acheulean toolkit remain scarce. The earliest European hominin crania associated with Acheulean handaxes are at the sites of Arago, Atapuerca Sima de los Huesos (SH), and Swanscombe, dating to 400-500 ka (Marine Isotope Stage 11-12).

Article Synopsis
  • This study presents the first rainfall record from speleothems in central North Africa during the last glacial period, identifying three major wet phases between 65-33 ka.
  • These wet periods correspond with shifts in Earth's orbital patterns and coincide with increased rainfall linked to North Atlantic moisture sources.
  • The findings suggest that these wetter conditions supported the expansion of modern humans and their interaction with Neanderthals, with migrations influenced by changes in climate, particularly dry phases after 50.5 ka and wet phases between 37.5 and 33 ka.
