Johnson says the model shows that the decay of evidence from abandoned sites can not account for a stable population appearing to increase exponentially.
He says the Aboriginal population grew at about 40 per cent every 1000 years over the past 5000 years, and about 10 to 15 per cent in the 5000 years before that.
“It’s not a particularly fast growth rate in itself,” he says. “But when our time scale is 10,000 years, it’s very dramatic.”
