From their first appearance in the archaeological record, the varying degree of biface presence in individual assemblages has long been a notable aspect of discussions surrounding the nature of the Early Acheulean. These debates have largely focused on the relative influence of random processes, site formation dynamics, raw material constraints, biological and/or cultural groupings, and differences in ecology and activity. Here, we collate published technological information from Early Acheulean assemblages 1.8–1.2 Ma, attempting to document patterns of wider inter-assemblage variability, and focus on the potential role of seasonality in structuring some of this variation. We suggest that there are relationships between a number of lithic variables in the Early Acheulean that are a reflection of consistent activity variants and patterns of landscape use, and that these variables account for discrete clusters of sites according to shared technological bases. While data on seasonality at individual sites in this period are sparse, we hypothesise that there is a likely association between the absence of handaxes and dry season patterns of hominin behaviour, which may reflect a focus on bifaces during the wetter parts of the year. The implications of these findings for the Oldowan-Acheulean transition, seasonal patterns of hominin behaviour, and Early Acheulean landscape use are discussed.
