In short:

A new DNA study suggests the first humans came to the ancient landmass that is now Australia via two distinct routes 60,000 years ago — much earlier than previous genetic evidence.

Archaeologists say the research is the first to "comprehensively" close the gap between genetic and archaeological evidence, which places arrival about 65,000 years ago.

What's next?

Some scientists still believe the case is not settled, with more research needed to confirm the genetic time frame.
