Fig. 3: Reconstructed left hand of KNM-ER 101000.

Palmar (left) and dorsal (right) views. The following right elements were mirrored: hamate, lunate, Mc5 and proximal phalanx (second ray). See Supplementary Table 1 for a full list of element attributions and sides (where known). The outline is for illustrative purposes only and not an interpretation of the relative phalangeal lengths (see Extended Data Fig. 3 and Supplementary Fig. 3 for analyses of digit proportions). Scale bar, 10 mm. The hand outline was created by Francis Tre Lawrence.
