Aboriginal Australian genomes reveal Indian ancestry (2013)
It's an emotionally charged subject, which is unfortunate as it's <i>objectively</i> fascinating from a purely historical perspective.<p>The simplified and (generally) commonly accepted narrative is that a cohesive group arrived here 45-60,000YA, lived peacefully and in harmony with the land right up until Europeans arrived.<p>There's some debate about the megafauna extinctions, but no conclusive evidence either way.   (I did appreciate Dr Yuval Noah Harari's summary of the phenomenon in his book <i>Sapiens</i>.)<p>If it turns out that the original population was partly / mostly replaced (linguistically, culturally, genetically) relatively recently, that potentially complicates a lot of the cultural positioning.<p>As I say, it's a shame, as the migration (including ethno & linguistic) paths over the past ~100k years are just amazing.
