Experimental Archaeology and Technological Variability
Experimental archaeology plays a central role in lithic studies by exploring the technical feasibility of proposed manufacturing procedures. However, its interpretive value depends on how experimental results are integrated with archaeological variability. This paper argues that experimental archaeology does not provide proof of past technological practices, but rather identifies technological possibilities under controlled conditions. Focusing o…
Reevaluating the MacNeish Legacy Collections
A ground-breaking endeavor led by Richard MacNeish between 1966 and 1972 was the “Ayacucho Archaeological-Botanical Project” in south-central Peru. For more than ten years, we have reviewed the lithics recovered in this fieldwork. As part of this research, we carried out detailed reevaluations of the lithic remains from the lower strata of three caves excavated in this project. Presented here are the artifacts from the lower levels of Pikimachay,…
Esferoides líticos atípicos entre grupos de cazadores-recolectores de laregiónpampeana
3Artifacts made from non-local raw materials, some of which may have held symbolic value, havebeen recovered in various areas and archaeological sites of the Pampaean region associated withhunter-gatherer groups. Their presence has been interpreted as theresult of processes thatdeveloped especially during theLate Holocene, including the formation of extensive alliancenetworks, an intensification of social interaction, and long-distance exchange o…
Through the Eyes of the Megafauna
As humans expanded across the globe, the Americas were the last continents to be colonized. While debates persist regarding the timing and mechanisms of this process, it is widely accepted that by the Pleistocene–Holocene transition, the New World was populated from Alaska to Tierra del Fuego. During this period, hunter-gatherer societies demonstrated remarkable cultural and adaptive diversity, particularly in subsistence strategies and technolog…
