Resolving out of Africa event for Papua New Guinean population using neural network
Overview
Paper Summary
This study uses genomic data and simulations to challenge the previous idea that the Papua New Guinean population's unique genetic makeup comes from an extremely early migration out of Africa. Instead, they find a strong population bottleneck and slower growth are the primary reasons for the observed differences, suggesting PNG people are closely related to East Asians.
Explain Like I'm Five
A genetic study suggests that a population crash and slow growth, not an early exit from Africa, explain why Papua New Guineans seem so genetically different. They're likely close cousins of East Asians.

Rating Explanation
This study uses robust methods and large datasets to address an important question in human population genetics, presenting compelling evidence for a revised understanding of PNG demographic history. While some minor limitations regarding detecting low-level admixture and the inherent model-dependence exist, these do not detract significantly from the overall quality of the study.
