Abstract

Here we respond to Carter and colleagues’ (2013) remarks concerning our Science article (Irish et al., 2013). The goals for that article were to: 1) further characterize Australopithecus sediba by describing 22 Arizona State University Dental Anthropology System (ASUDAS) traits, 2) compare the traits in A. sediba with those previously recorded in other hominin samples, and 3) present initial phylogenetic analyses using these data. Given the subset of traits, out of 125 possible (below), and small A. sediba sample, our conclusion was that the results “further define [the species’] position relative to other genera,” but that “the phylogenetic place of A. sediba has not been settled” (Irish et al., 2013: 1233062–12330624). These goals were met, as a basis for more comprehensive study. Below we summarize and reply to the eight objections of Carter et al. (2013), while: 1) demonstrating that there is a strong theoretical basis for using the ASUDAS in phylogenetic analyses, 2) presenting results (which corroborate previous cladistic analyses) that are congruent using different methodological approaches, and 3) introducing new results using a second outgroup, Pan troglodytes, that fully uphold our original analysis.
