Are the Kow Swamp hominids "archaic"?

Initial reports of hominids recovered at Kow Swamp, in the Murray Valley of Victoria indicated that, on the basis of cranial analyses, there was a "survival of Homo erectus features in Australia until as recently as 10,000 years ago (Thorne and Macumber, 1972, p. 316). This claim was later refuted by others, who suggested that artificial cranial deformation may have been responsible for at least some of the distinctive and "primitive" traits seen in the Kow Swamp individuals. Previous research by this worker and others has indicated that taxonomic traits at both specific and subspecific levels are present in hominine femora. Therefore, it may be possible to evaluate the "primitiveness" of the Kow Swamp sample on the basis of their femoral anatomy. Morphometric analyses were undertaken, using as controls femora of Romano British, Tasmanian, and other Murray Valley populations. On the basis of bivariate and multivariate analyses it was found that, at least in this single element of the postcranium, no primitive features were present. The Kow Swamp sample, in fact, shows a very close morphometric relationship with all included Homo sapiens controls and is significantly distinct from Homo erectus.
