The human footprints of Ojo Guareña (Phys.org 08/3/21)

The CENIEH has participated in the study of the prints of bare feet found at the Sala y Galerías de las Huellas site in the Ojo Guareña Karst Complex (Burgos), which are the marks left in a soft floor sediment of an exploration by a small group of people between 4600 and 4200 years ago.

Neanderthal and early modern human stone tool culture co-existed for over 100,000 years (phys.org 01/03/21)

The Acheulean was estimated to have died out around 200,000 years ago but the new findings suggest it may have persisted for much longer, creating over 100,000 years of overlap with more advanced technologies produced by Neanderthals and early modern humans.
