The paper introduces a statistic to detect population continuity and ghost admixture in ancient genomes by analyzing temporal drift and admixture effects.

This study uses whole-genome sequencing and machine learning to reconstruct demographic history and gene-flow patterns among African populations, finding that tree-like histories with gene-flow pulses better explain genetic diversity than continuous gene-flow.

This paper introduces two methods for estimating divergence times from DNA sequences using coalescent theory and demonstrates their robustness to demographic complexities.

The paper analyzes ancient genomes from southern Africa to show that modern human divergence occurred over 260,000 years ago, pushing back previous estimates and linking it to the Middle Stone Age and anatomical changes in the fossil record.
