New fossils reveal the hand of Paranthropus boisei

Abstract

When Mary Leakey discovered the OHrCe5 cranium of Paranthropus boisei alongside Oldowan stone artefacts, it was declared rCLthe oldest yet discovered maker of stone toolsrCY1. Whether Paranthropus made and used
tools has been debated ever since, largely because there are no known
hand bones that can be definitively attributed to this genus. Here we
report fossil hand and foot bones unambiguously associated with
craniodental material of P.rCeboisei. KNM-ER 101000 demonstrates that P.rCeboisei shared key manipulative and bipedal adaptations with the genus Homo. Moreover, the hand morphology of KNM-ER 101000 converges on that
of gorillas in ways that are consistent with manual food processing and
would have facilitated powerful grasping, such as that used in climbing.
These fossils suggest that P.rCeboisei was capable of tool making and use
in some capacity while also supporting the proposed dichotomy of
distinct dietary adaptations between Paranthropus and Homo. In addition
to offering insights into the poorly known postcranial functional
anatomy of Paranthropus, this discovery illuminates broader patterns of hominin hand evolution and tool use.

First known fossil hand of the hominin Paranthropus boisei

Hand bones from a human relative, found in Kenya,
reveal features similar to those of living gorillas,
complicating the evolutionary history of hand and
tool manipulation.
