Two recent interesting genetic papers:

1. Open Access Investigating the origins of eastern Polynesians using genome-wide data from the Leeward Society Isles, by Hudjashov et al., at Scientific Reports (2018)

Abstract:

The debate concerning the origin of the Polynesian speaking peoples has been recently reinvigorated by genetic evidence for secondary migrations to western Polynesia from the New Guinea region during the 2nd millennium BP. Using genome-wide autosomal data from the Leeward Society Islands, the ancient cultural hub of eastern Polynesia, we find that the inhabitants’ genomes also demonstrate evidence of this episode of admixture, dating to 1,700–1,200 BP.
