For most of history sea levels were much lower than they were today, with more land for people to cultivate on. However, in recent years temperatures have caused our ice caps to melt resulting in higher sea levels. These higher sea levels means much of our history has become lost underwater. Recently researchers have found new archaeological artefacts that help us fill in the gaps of Indigenous culture and history such as grinding stones and stone cutting tools which predate 5000 BC.

To discuss these findings we were joined by Deputy Director of the ARC Centre of Excellence for Australian Biodiversity and Heritage, Sean Ulm.
