The Equipment of the Tyrolean Iceman: Innovation versus Adaptation in the Cultural Evolution of Prehistoric Technologies.

Abstract

This study argues that the equipment of the Tyrolean Iceman offers a unique perspective for understanding the macroevolutionary-scale functional continuity between later Pleistocene and Holocene human technologies. The Iceman was discovered in 1991 in the Ötztal Alps and can be dated to around 3300 BC, corresponding to the North Italian early Copper Age. In his gear there are several technologies which are rarely found at prehistoric archaeological sites, including archery equipment, a complete set of clothing, and a personal tool kit. Our paper will discuss this technological assemblage within the framework of cultural evolutionary theories (subsequently abbreviated as CET). According to the concept of cumulative culture, tools and technologies may become the subject of cultural "descent with modification" which leads to the emergence of complex technological innovations. In conventional narratives, the Neolithic represents the single greatest macroevolutionary transition in human cultural evolution, accompanied by a whole set of novel innovations and encompassing the transition to agriculture. However, as we highlight, the Iceman's equipment includes several technologies with a pre-Neolithic cultural origin. Earlier variants of these technologies were used by cultural groups belonging to the Mesolithic and even the Upper and Middle Paleolithic. Our main goal will be to present an explanatory framework for this macroevolutionary-scale technological continuity. In order to achieve this goal, we explore the heuristic value of two basic concepts of cultural evolutionary explanations-namely, the concepts of innovation and adaptation. Building on this background, we present an overview of the data currently available on the evolutionary history of each technological adaptation found in the equipment of the Iceman. Our results suggest that these technologies were not primarily cultural innovations, but simultaneously they were "obligatory" functional adaptations with a deep evolutionary history.
