The paper uses a coalescent model to show that all modern humans share deep ancestral structure from two populations that admixed ~300k years ago, with the minority ancestry linked to deleterious effects and majority ancestry linked to archaic human divergence.

The paper shows a bottleneck model fits worse than a panmictic model, refuting a recent claim of a severe population bottleneck during the Early to Middle Pleistocene transition.

The paper identifies and resolves false population size peaks in PSMC analyses, showing they result from parameter settings and not true population dynamics.

The paper extends coalescent-based inference to deep time scales using high-quality genome assemblies, revealing a population size peak in humans, chimpanzees, and bonobos around 3-6 million years ago.

This paper introduces PSMC+, an extension of the PSMC algorithm that accounts for background selection in demographic inference, improving accuracy in effective population size estimation.

This study uses long-read sequencing to analyze 88 Lepidoptera genomes, identifying genomic signatures linked to conservation concerns like low heterozygosity and high inbreeding.
