Well always keen to better understand the evidence. Seems to me there's a smoking gun with fauna/megafauna extinctions closely associated with man's arrival all around the globe. Possibly the only immune continent being Africa where we're now doing our best to make up for lost time...
It would be interesting to see where that particular piece of research leads ....
The thing is, in Australia at least, that the Original people have been here for 100's of 1000's of years - well before the land bridge theory says they 'arrived'.
As such they co-existed with megafauna for 10's to 100's of 1000's of years - both witnessing meteor impacts (local extinctions and 'nuclear winter) , decades long droughts, decades long floods, glaciation, volcanic activity, sea level rises, inundation, and sea level falls, climate changes, etc - along with any pole shifts ....
Original law has strict custodianship of creation through the totemic system etc - hunting anything to extinction is distinctly at odds with the entire culture.
None of this is to say that Dingoes didn't displace Thylacines from some areas, but overall you would be surprised at what still exists, hidden, throughout the country.
I am sure there will be interesting revelations, both from the bones, and directly, when the time, and importantly, the conditions are right ....
