The paper develops new theory to explain a 5-fold decline in Neanderthal effective population size over 20 ky using genetic variation and geographic structure.

The paper introduces a deterministic algorithm for estimating population history from genetic data, improving speed and accuracy over previous stochastic methods.

The paper shows that in resource competition scenarios, there is no evolutionarily stable strategy, and the Nash equilibrium is unstable yet predictive of behavior under certain conditions.

The paper documents the earliest known interbreeding between ancient human populations and an expansion out of Africa early in the middle Pleistocene.

Legofit estimates population history and admixture parameters simultaneously, outperforming existing methods by addressing statistical identifiability and model selection.
