On the basis of allele frequency spectrum, it was shown that the recent admixture model had the best fit to the results while the ancient population sub-structure model had no fit–demonstrating that the best model was a recent admixture event that was preceded by a bottleneck event among modern humans—thus confirming recent admixture as the most parsimonious and plausible explanation for the observed excess of genetic similarities between modern non-African humans and Neanderthals.
Na osnovi spektra frekvencije alela pokazalo se da model recentne primjese najbolje odgovara rezultatima dok im model supstrukture drevne populacije uopće ne odgovara – to pokazuje da je najbolji model bila recentna primjesa kojoj je prethodio efekt grla boce među modernim ljudima – potvrđujući tako recentnu primjesu kao najparsimoničnije i najizglednije objašnjenje uočenog viška genskih sličnosti između modernih neafričkih ljudi i neandertalaca.
