There is very good evidence for the genetic and geographical isolation of Tasmania, but that doesn’t imply genealogical isolation. There are no peer-reviewed publications on the genealogical isolation of Tasmania, because genealogical isolation might be too difficult to evidentially establish, it might be outside our view.
Note, the “nearly” qualifier only becomes required if AE are really recent, say less than 8,000 kya, and Tasmania was in fact genealogically isolated. I think most would gladly consider AE at 10,000 years ago or even more ancient. So this is a lot of hoopla about a boundary condition and less than 0.001% of the population.
