Australopithecus robustus is thought by some to be transitional between apes and humans. But the evidence shows that this is not so. Robustus ‘possessed very ape-like upper bodies with long, powerful arms that would have made them agile tree climbers’.[1]

The pelvis and hip morphology suggests that ‘the gait of P. robustus probably resembled that of the ‘gracile‘ australopiths’.[2] The fossils show that robustus had huge chewing teeth and rugged skulls, but they also had small brains and bodies like other apes.[3]

The semicircular canal dimensions of robustus are similar to those of extant great apes, as determined by CT scans of the bony labyrinth of the inner ear.[4]

The fossils of robustus are extremely robust (hence the name), and many scientists have attributed it to a side track to human evolution ‘because their teeth and skulls were so specialized and because they coexisted with more plausible ancestors after 2.5 million years ago’.[5] Thus, robustus is not greatly important in terms of our supposed evolution.

It is plain that robustus was simply an ape with no real similarities to humans at all. Only with imagination, can evolutionists claim it is transitional — because the evidence shows nothing more than an ape.
