What claim did Thorne make? What evidence supported his claim? Mungo Lady and Mungo Man

Dr. Thorne proposed a view called regional continuity.

Dr. Thorne believed that it was actually a Homo sapien species that migrated from Africa, and this was the only species to ever leave Africa.

Mungo Lady and Mungo Man are the oldest humans ever found in Australia.

The DNA sequence of Mungo Man is unlike any other human, living or fossil.
