Somebody (I don't remember who) suggested that Australian Boabab trees were potential evidence of the direct population of Australia from Africa by a pre-Aboriginal people, based on the idea that the fruit of the Boabab tree would be an excellent food source for a long cross-ocean crossing, as well as supposed "African" characteristics in the Kimberley petrographs found in the same area as the trees. The theory is fringe-science at best (and I believe slightly offensive to Aboriginals) but I've been curious about the origin of the trees since coming across the theory. I skimmed through the paper but didn't see any estimate for a date for the genetic diversion of the Australian Boababs.
