Ascertain the extent and impact of modern and archaic human migrations in Oceania

Ascertain the extent and impact of modern and archaic human migrations across Oceania by reconstructing migration routes and quantifying their demographic effects on island and coastal populations using genome-wide analyses.

Background

The authors emphasize that Oceania has a complex demographic history involving multiple waves of settlement and admixture, including archaic hominin introgression.

Despite prior studies, they explicitly note that the overall extent and impact of both modern and archaic migrations that may have occurred across the region remain unresolved, motivating their comprehensive genomic analyses.
