Multiple approaches to the study of bifacial technologies.

TL;DR: Almeida et al. as mentioned in this paper present a survey of how bifacial technology changed through time and according to different environments, complementing the evolution of human cognition and physical abilities, from the earliest African bifaces to North American Woodland projectile points.

Abstract: Bifacial chipped stones have been used by archaeologists to document the evolution of human technology and cognition during the Pleistocene and as index fossils for a myriad of cultures in both the Old World and the New. Bifaces provide some of the most convincing dimensions of stylistic variability observable in stone tool assemblages. With an international cast of contributors, from St. Petersburg to South Carolina, this volume shows how bifacial technology changed through time and according to different environments, complementing the evolution of human cognition and physical abilities. It also addresses how the different technological and social systems of past hunter-gatherers are reflected in bifacial technology, from the earliest African bifaces to North American Woodland projectile points.
