Abstract

American archaeology has long been focused on reconstructing past cultures through the description and chronological ordering of items found in the archaeological record. This goal was most evident starting in the early 20th century through what became known as culture history, which in retrospect produced results based on common sense and ethnographic analogues rather than on formal theory. By the mid-1930s, some culture historians realized the lack of testability in their conclusions and began exploring Darwinian evolutionary theory as an alternative. However, their efforts were often ignored or ridiculed, and it wasn’t until the early 1980s that evolutionary theory and associated methods began to play significant roles in archaeology. This acceptance grew from the development of a genetics-based theory of cultural transmission and the introduction of phylogenetic methods into anthropology and archaeology. These methods offered the necessary means for distinguishing between simple historical continuity—one thing following another chronologically—and heritable continuity—how one thing is related to another in terms of descent. Two concepts that play key roles in the reconstruction of cultural phylogenies are tradition and lineage, the former representing patterns of phylogenetic relationship and the latter patterns of genealogical descent.
