Nawarla Gabarnmang is the archaeological site in Jawoyn country from which the 35,000 year old piece of ground-edge axe was found.
In his book The Artificial Ape, Dr Timothy Taylor convincingly argues that humans are biologically a product of technology. If Taylor is correct, then the ground edge stone tool pictured is of enormous significance. Stone tool-use among our earliest hominid ancestors dates to 3.4 million years ago, but the use of grinding to sharpen stone tool edges is very recent. This is the oldest ground-edge stone tool ever found and represents bleeding edge technology 35,000 years ago.
