The Kalahari Origin Hypothesis of Bipedalism
The author analyzed that repeated
asteroid impacts caused Gondwanaland
to break apart, allowing seawater to
go into the fractured crust and cause
gigantic magma explosions at J/K
boundary. It is plausible that the
main part of magma was sent out of
the atmosphere to make a moon whilst
the rest got stuck to the surface by
the earth’s gravity, cooled and
solidified to make a plateau
stretching about 4 million square
kilometers without water system at
1,000 meters above sea level. The
Kalahari is a sign of a giant impact.
Raymond Dart said regarding the Taung
Skull, “This prairie land between the
tropical forests and Taungs had been
an effective barrier from Cretaceous
times (120 million years ago) against
the southward migration of any
semiarboreal anthropoid such as the
gorilla and chimpanzee. Yet this new
anthropoid group must have forced its
way through the barrier no more than
one million years ago, had sufficient
intelligence to find types of food
other than fruit and the agility and
resourcefulness to avoid the
carnivorous beasts of Africa.”
(Dart 1959)
It is plausible that the harsh
environment of the Kalahari made
Australopithecus bipedal. Because it is
so flat, having a higher perspective can
increase the chances of survival by
providing early warning of predators’
attack and finding food.
