Understanding the movements and migrations of ancient humans can often be an intricate puzzle. In this episode, we explore this fascinating topic with Dr. Yue-Chen Liu, who has delved into the peopling of the Micronesian islands. By examining 164 ancient human remains from five different archaeological sites in Remote Oceania, along with 112 present-day individuals from the same area, Liu and his team have unraveled the intricate threads of human migration.

Dr. Liu explains how their analysis unveiled five migratory streams into Micronesia, with three being East Asian-related, one Polynesian, and a fifth from a Papuan source related to mainland New Guineans. Interestingly, this Papuan source, derived from male migrants around 2000-2500 years ago, was distinct from the New Britain–related Papuan source for southwest Pacific populations.
