For more than a million years their australopithecine predecessors — Lucy and her kind, who walked upright like us yet still possessed the stubby legs, tree - climbing hands and small brains of their ape forebears — had thrived in and around the continent's forests and woodlands.
This was a presentation given by Tom Schoenemann of the University of Michigan at Dearborn, and what he did was to survey cranial capacity and body weight data, so brain size and body weight data for a bunch of modern humans and also [a] fossil one, and he plotted all of this on a graph and he determined that the brain size of the Flores hominid relative to her body size more closely approximates that what you see in the Australopithecines, which are much older, you know.
So, given three possible explanations for what the Flores hominid is, and those three possibilities are that, you know, a dwarfed species descended from Homo erectus or an Australopithecine or a microcephalic modern human, he says that the most parsimonious diagnosis is the one that requires the fewest assumptions — would be microcephaly.
For this reason, a few anthropologists, such as David Begun at the University of Toronto in Canada, have suggested that our ape ancestors spent a formative period in Europe — although they still agree that later hominin evolution, including that of the australopithecines and the origin of our own species, occurred solely in Africa.

The predicted stature of S1 exceeds any australopithecine: a mean value of 158 cm was estimated for the large Au.
The use of the modern human reference samples for stature estimates are inappropriate because they assume body proportions akin to modern humans, which are not possessed by australopithecines.
In order to contextualise the australopithecine and early Homo stature estimates and range of variability obtained from the footprints within a broader picture (Figure 12), and to compare them with a larger sample, we extended our analysis to consistent data based on skeletal elements, namely femurs (see Materials and methods for details).
Except for having small rather than large teeth, and a quadrupedal rather than a bipedal pelvis, pygmy chimpanzees are remarkably like early gracile australopithecines in their skeletal dimensions.
In a small teaching resource booklet, which to my knowledge is his latest written opinion on the matter (Oxnard, 1991:30 - 31), he first gives the basic data on australopithecine postcranial anatomy, then discusses possible functional interpretations, and finally comes to what it means for human evolution.
What AiG missed in that paper is — well, they obviously missed the entire message of it, but the implication which Spoor et al. draw for australopithecine locomotion is encapsulated in a statement on p. 648,
