... Newly discovered lumbar
vertebrae contribute to a near-complete lower back of Malapa Hominin 2 (MH2), offering additional insights into posture and locomotion in Australopithecus sediba. We show that MH2 possessed a lower back
consistent with lumbar lordosis and other adaptations to bipedalism, including
an increase in the width of intervertebral articular facets from the upper to
lower lumbar column (‘pyramidal configuration’). ...
MH2’s nearly complete middle lumbar vertebra is human-like in overall shape
but its vertebral body is somewhat intermediate in shape between modern humans and great apes. Additionally, it bears long, cranially and ventrally oriented costal (transverse) processes, implying powerful trunk musculature. We interpret this combination of features to indicate that A. sediba used its
lower back in both bipedal and arboreal positional behaviors, as previously suggested based on multiple lines of evidence from other parts of the skeleton & reconstructed paleobiology of A. sediba. ...
"... Analysis of the fossils suggested that MH2 would have had an upright posture and comfortably walked on two legs, and the curvature of their lower back was similar to modern females. However, other aspects of the bones’ shape suggest that as well as walking, A. sediba probably spent a significant
amount of time climbing in trees. ...
Despite the presence of climbing adaptations, A. sediba also demonstrates clear evidence for bipedal locomotion. The knee and ankle possess human-like adaptations to bipedalism, demonstrating a valgus angle of the femur and a human-like ankle joint..."
"Furthermore, analysis of dental calculus from Malapa Hominin 1 (MH1) indicates
that this individual’s diet was high in C3 plants like fruit and leaves,
similar to savannah chimpanzees and Ardipithecus ramidus..."

Based on dental evidence.
Only incredible idiots assume their Plio-Pleistocene ancestors had snorkel noses.

Based on dental evidence.
-DDD
Based on wishful thinking.
0 evidence.
Savanna chimps running after antelopes??? :-DDD
The antelope runners become more & more idiotic:
evidence = MH1 had chimp-like diet.
Only incredible idiots assume their Plio-Pleistocene ancestors had snorkel >> noses.
Only incredible idiots are convinced human noses could not have been used for diving:
