a–f, Box-and-whisker plots of crown area of the dm2 (a), C1 (b), P3 (c), C1:P3 ratio (d), P4 (e) and M1 (f) in A. ramidus, A. anamensis, A. afarensis and A. africanus compared with A. deyiremeda. The box in each plot represents the first to third quartiles of the dimensions, the line inside the box shows the median, and the horizontal lines outside the box represent the maximum and minimum values. The sample size is indicated by n. A statistical summary of the dental metrics used for this figure is provided in Supplementary Table 2 and Supplementary Data 2. The data were compiled from refs. 18,30 (A. ramidus), refs. 26,29 (A. anamensis), refs. 10,20,21,27 (A. afarensis) and ref. 28 (A. africanus).
