TL;DR: It is demonstrated that indigenous Australians, New Guineans and Andamanese do not derive substantial ancestry from an early dispersal of modern humans; instead, their modern human ancestry is consistent with coming from the same source as that of other non-Africans.

TL;DR: Analysis of the oldest genomes suggests that there was an early split within Beringian populations, giving rise to the Northern and Southern lineages, and that the early population spread widely and rapidly suggests that their access to large portions of the hemisphere was essentially unrestricted, yet there are genomic and archaeological hints of an earlier human presence.

TL;DR: Differences in the recombination landscape across the genome and between populations are driven by variation in the gene that encodes the DNA binding protein PRDM9, and a demography-aware method is developed and applied to 26 diverse human populations, inferring population-specific recombination maps.

TL;DR: Evidence that selection against Neanderthal ancestry was due to higher genetic load in Neanderthals resulting from small effective population size, rather than widespread Dobzhansky–Müller incompatibilities (DMIs) that could contribute to reproductive isolation is found.

TL;DR: This article developed an exchangeable neural network that performs summary statistic-free, likelihood-free inference for recombination hotspot testing, which can be applied in a black-box fashion across a variety of simulation-based tasks.
