As a lurker who's merely read some of Leakey's popular science books,
I am unconvinced that hominids such as Homo Habilis or the
Australopithecines would have practised persistence/endurance hunting.
1) If they did, surely they would have been mobile enough to migrate
out of Africa, and Homo Erectus is the first human to do this.
2) The Austraopithecines, like gorillas and unlike homo and
chimpanzees, had strong sexual dimorphism. This implies that the males
of a group were unrelated and competed with each other for access to
related females, which implies they were power rather than endurance
athletes.
Therefore this line of evidence seems poor ammunition to use against
the various crackpot alternate theories seen on this group.
"Specifically, longer, more linear bodies are better adapted
for heat loss in dry open environments, where evaporative
heat loss from sweating is very effective. All modern-day tall
"elongated"
African (e.g., Nilotics) are restricted to such environments."

"Two indepandent lines of research converged on the
conclusion that early Homo was an efficient runner, the first human
species to be so (Leakey 1994:55)."
They were referring to the Turkana Boy and his long legs, not A'piths
or the other questionable cousins.
