Especially with their long arms, they resembled australopithecines
from the neck down.
But a tooth brought back from the dig seemed to suggest something more like Homo erectus; the idea of an australopithecine
never even crossed Brown's mind.

Ample evidence has shown that australopithecines
were walking upright by this time, but the first traces of this skeleton - the four bones of an instep and beginning of the big toe - suggested that this species also was capable of grasping and climbing like a chimpanzee.
From the same publishers, Tombs, Graves Se Mummies, edited by Paul Bahn, charts fifty `extraordinary' archaeological discoveries based on human remains, from the 3 million-year-old australopithecine
from Ethiopia, to the fate of the Romanovs at the hands of the Bolsheviks in 1918.
erectus, with the brain showing an increase in size equal to that of the entire australopithecine
brain (Blinkov & Glesner, 1968).
Most of our evolutionary increase in brain size occurred after we reached the australopithecine
Chronological and ecological implications of the fossil Bovidae at the Sterkfontein australopithecine
In 1974 an American anthropologist, Donald Johanson, unearthed an unprecedentedly complete and ancient skeleton of an australopithecine
female, who was given the name Lucy.
Without a more complete skeleton, there's no way to know whether the jaw is the earliest representative of Homo "or just another australopithecine
," adds paleoanthropologist Christoph Zollikofer of the University of Zurich.
Most homo and earlier Australopithecine
species never had very large populations, and they all went extinct relatively quickly, compared to their nearest relatives, the great apes.
Similarly, the increased consumption of dietary fat has been linked to the evolution of vastly bigger brains in early Homo (especially between 700,000 and 250,000 years ago), relative to their australopithecine
A good way to become familiar with australopithecine
anatomy would be to use a point-by-point comparison of their skeletons with those of apes and humans.
That famed australopithecine
"Lucy" was very possibly male, yet by convention all smallish skeletal remains are female, which obviously skews the interpretation of home-sites and grave-goods.
Taken individually and collectively, population genomics studies strongly suggest that our lineage has not experienced an extreme population bottleneck in the last nine million years or more (and thus not in any hominid, nor even an australopithecine
species), and that any bottlenecks our lineage did experience were a reduction only to a population of several thousand breeding individuals.
