This is not a trivial finding.

It means that the connection between the Aegean collapse and the Bronze Age Collapse of the Levant is not just cultural or commercial but is visible in the biological ancestry of the people who moved between regions.

The Philistines were not Canaanites who had adopted Aegean material culture; they were people who came, at least in part, from a population with genuine biological connections to the Aegean world.

What the science has not established is the origin of the other Sea Peoples groups.
