Not studies of Australian Aboriginals specifically but it is obviously hard to find large populations of insulated indigenous peoples to study.Originally Posted by David48atTD
South America probably has (or had until recently) the largest such populations.
The studies carried out by Napoleon Chagnon on the Yanomamo are considered some of the best available on capturing what human civilisation must have been like in pre-history.
We are all homo sapiens and it is likely that the behaviour of the Yanomamo is typical of pre-state human societies.
The behaviour is typically a semi-permanent state of tribal hostility where anyone wandering into the wrong territory can expect to be killed.
Inter-village raids are common with the objective being to kill males and abduct females.
In the words of Thomas Hobbes: life in pre-state human society was almost certainly 'nasty, brutish and short'.
