The paper introduces a Bayesian MCMC method for inferring admixture graphs and applies it to Native American and Arctic populations, finding that the Koryak population, not Saqqaq, is the best proxy for gene flow into Athabascans.

The paper identifies extreme selective sweeps on the human X chromosome that displaced Neanderthal admixture around 50,000 years ago, suggesting a population without Neanderthal admixture contributed these haplotypes.

The paper estimates mutation rates in great apes and finds a recent slowdown in the human mutation rate per year compared to other species.

Ohana improves admixture analysis by introducing a new optimization algorithm and Gaussian-based tree estimation, showing better likelihood results than existing methods.
