The age of the Taung child remains more difficult to determine and is the focus of a current dating project.It demonstrated the power that the people like British tabloid magnate Alfred Harmsworth held in society, but the scientific process in the case of Piltdown was relatively immune to this.Instead of it being a direct ancestor of later hominins and thereby of humans, some researchers believe that A. Evidence of human-like sexual dimorphism in the lumbar spine has recently been described in the (bipedal) primate A. This character of morphology has been seen as an evolutionary adaptation by female bipeds in order to more efficiently bear load on the lumbar column during pregnancy, an adaptation that non-bipedal primates do not need.africanus evolved into Paranthropus, and specifically that P. A 2011 study using ratios of strontium isotopes in teeth suggested that both A. robustus groups in southern Africa were patrilocal: that is, females tended to settle farther from their region of birth than did males.

Keith's persistent animus towards the Taung child discovery caused serious consequences; from Dart's announcement in 1924, it took nearly 30 years before the inevitable methods of science revealed the Piltdown man hoax and supported the validity of the claims (of hominin status) for Australopithecus.

But his claim was rejected by the scientific community, generally in deference to the broadly-held idea (idée fixe) that the early development of the line to humans required that a large cranium ("big brain") would precede bipedal locomotion; (see below, Mrs. And the rejection was buttressed by the widespread belief then, especially in British academia, that the Piltdown Man recently found in England was the likely progenitor of the human lineage.

(Piltdown man was later exposed as a forgery.) Sir Arthur Keith was an anatomist and anthropologist fellow in 1924, and a scientist whose personal prejudice looked to Europe—not to Asia or Africa—as the place where the early hominins would be shown to have emerged.

In 1936, the Sterkfontein caves yielded the first adult australopithecine, substantially strengthening Dart's claim for Broom.

Later, Broom classified an adult endocranial cast having a brain capacity of 485 cc (found by G. Barlow) as Plesianthropus transvaalensis (near-man from Transvaal).
