An archaeological dig in New Guinea by UNSW scientists has unearthed artefacts to provide strong evidence that a Neolithic period existed there 5000 years ago.
It is well known that agriculture developed independently in New Guinea 7000 years ago, but evidence of its influence on how people lived has eluded scientists – until now.
A study of the fossil teeth of megafauna from Cuddie Springs in NSW suggests that climate change had a significant impact on the diets of these giants and may well have been a primary factor in their extinction.
Most species of gigantic animals that once roamed Australia had already disappeared by the time people arrived, a major review of the available evidence has concluded.
