You mean it doesn't fit your preconceived notions. They go where the data
leads them, not the other way around.
Have you ever been allowed to study real finds?

And now for the REAL abstract, not the made up stuff from mv (whi is not to be

The foot of Homo naledi
Abstract
Modern humans are characterized by a highly specialized foot that reflects
our
obligate bipedalism. Our understanding of hominin foot evolution is,
although,
hindered by a paucity of well-associated remains. Here we describe the
foot of
Homo naledi from Dinaledi Chamber, South Africa, using 107 pedal elements,
including one nearly-complete adult foot. The H. naledi foot is predominantly
modern human-like in morphology and inferred function, with an adducted
hallux, an elongated tarsus, and derived ankle and calcaneocuboid joints. In
combination, these features indicate a foot well adapted for striding
bipedalism.
However, the H. naledi foot differs from modern humans in having more curved
proximal pedal phalanges, and features suggestive of a reduced medial
longitudinal arch. Within the context of primitive features found
elsewhere in
the skeleton, these findings suggest a unique locomotor repertoire for H.
naledi,
thus providing further evidence of locomotor diversity within both the
hominin
clade and the genus Homo.
Note the REAL last sentence, not the one mv rewrote.
"We show here that the foot of H. naledi is predominantly modern human-like
in bony morphology and inferred function. When considered against the
primitive
features found elsewhere in the H. naledi postcranial skeleton10, these
results
indicate a locomotor repertoire that would have been distinct from that of
other
basal members of the genus Homo, such as H. erectus and H. habilis. The
foot of
H. naledi thus expands the range of locomotor diversity in both the hominin
lineage and the genus Homo."
