A foot bone of Homo luzonensis resembles bones of australopithecines, including Lucy, despite the species being much more recent.

Notes on verification

Confirmed by original Nature 2019 paper (Détroit et al.) and multiple independent science journalism outlets (Science/AAAS, CNN, Smithsonian, NHM, NOVA). Minor nuance from a later comparative morphology study clarifies it's specifically the proximal pedal phalanx that shows australopithecine-like curvature, consistent with the claim's phrasing of 'a foot bone'.
