THE ORIGINS OF HUMAN TECHNOLOGY

Homo heidelbergensis is an extinct species of archaic human that lived in Europe, Africa, and possibly Asia from approximately 700,000 to 300,000 years ago. The species is named after the town of Heidelberg, Germany, where the first specimen was discovered in 1907, and named shortly thereafter by anthropologist Otto Schoetensack. Homo heidelbergensis is considered to be the most recent comm💛on ancestor between modern humans and Neanderthals.

Although stone toolmaking has been attributed to both Homo habilis and various australopithecines between 2.5 and 1.5 million years ago, the Acheulean stone tool industry of Homo erectus and Homo heidelbergensis constituted a technological revolution, best characterized by the handaxe as offered here (see also Lots 47 and 48). Acheulean handaxes were the first stone tools to be worked symmetrically on both sides, and would have been used for cutting, hunting, butchering, and digging in soil. The shaping of two-sided handaxes – also known as bifaces – through the process of knapping (r𓃲emoving flakes around the 🍌core of a stone) is a complex skill that archaeologists have attributed to increased prefrontal brain activity and a high degree of working memory, both vital to the development of modern human cognition.
