Supplementary_Data_S1-S5 for the Manuscript PNAS2025-35242

Supplementary data for the manuscript titled "Early catarrhine evolution in the light of semicircular canal and vestibule shape" ref. PNAS2025-35242 The compressed folder contains: Supplementary Data S1 - Interactive 3D plot for the canonical variate analysis of the anthropoid semicircular and canal shape (Figure 4). Supplementary Data S2 - Interactive 3D plot for the phylomorphospace based on a phylogenetically-aligned component analysis of the anthropoid semicircular and canal shape including Saadanius as a stem catarrhine less derived that pliopithecoids (Figure 5). Supplementary Data S3 - Interactive 3D plot for the phylomorphospace based on a phylogenetically-aligned component analysis of the anthropoid semicircular and canal shape including Saadanius as a stem cercopithecoid less derived than Victoriapithecus (Supplementary Figure S4). Supplementary Data S4 - Interactive tree plot showing the evolutionary model hypotheses fitted to the shape data. Supplementary Data S5 - R code and associated data to perform all the analyses described in the paper.
