Abstract:
Some years ago, The Homogeneity to Multiplicity Model (HMM) was introduced as a structural framework for understanding the appearance and evolution of early stone tool techno-systems. Presently, the HMM provides an alternative and complimentary conceptual scheme with which to explain how and why particular morphotypes appeared and proliferated through time and space. This paper is especially dedicated to the very first stage of this model, Homogeneity, which refers specifically to the origins of human technologies in Africa more than 3 million years ago. Research on numerous ancient African and Eurasian stone tool assemblages provides empirical examples indicating that the oldest known hominin technologies most likely emerged out of a previous phase of long-term practice of percussive technologies. While primates and other animals make and use tools, only humans have evolved complex operative schemes involving chains of action that are intermediary to the primary goal of satisfying a survival-related desire; such as accessing or processing foodstuffs. Compared to other species, humans demonstrate total reliance upon toolmaking for survival. This adaptive strategy precludes elaborate and lengthy learning and socialization processes that are the very foundation of human material culture. The Homogeneity phase marks a turning point for humanity, from which our destiny would be irrevocably detached from that of all other animal species with which we share the planet. It characterizes the very basic structural nature of first toolmaking, with simple cores, flakes and percussion implements, which provided the foundational Potential to evolve towards Oldowan Variability.
