Boas Coordinates, Bookstein coordinates, Geometric morphometrics, Procrustes Coordinates, Shape analysisBy: RITWIK BANERJEE – This study compares legacy and modern coordinate systems used in shape analysis, evaluating their impact on morphometric outcomes using a Homo naledi third metacarpal (MC3). Nine fixed landmarks were placed along the palmar curvature of a Homo naledi MC3 (MorphoSource ID: 0000S2122). Thirty specimens were simulated by applying small positional noise…
