Media coverage has at times emphasised his claims of mysterious races. Pettigrew suggests that the Gwion Gwion paintings depict people with 'peppercorn curls' and small stature that characterise San groups; he speculates that African people travelled, shortly after the Toba eruption some 70,000 years ago, by reed boat across the Indian Ocean, provisioning themselves with the fruit of the baobab tree. The Australian archaeological community has generally not accepted such claims and believes that Gwion Gwion are indigenous works. For example, Dr Andrée Rosenfeld argued that the aesthetics of the art did not support claims for a non-Aboriginal origin when comparison is made to the aesthetic value of contemporary Aboriginal art. The Australian Archaeological Association in a press release stated, "No archaeological evidence exists which suggests that the early colonisation of Australia was by anyone other than the ancestors of contemporary Aboriginal people", the release quoted Claire Smith: "such interpretations are based on and encourage racist stereotypes".
