Abstract

Multiple species of pigs are endemic to Maritime Southeast Asia. Some of them exhibit a distinctive tooth shape and mitochondrial DNA haplogroups, but the history of pigs in this region is not clear. Stanton et al. collected genetic data from 117 modern, historic, and ancient individuals and examined morphometric data from over 700 modern and archeological samples. After comparing with 585 published mitochondrial genomes, the authors found that domestic pigs, which were likely introduced by Austronesian-speaking groups, contributed to most pigs found today from Hawaii to the Philippines. However, early specimens from these groups show no admixture with endemic species, mirroring the lack of mixture between these early human groups with local groups during their initial migrations.
