Models of Migration into the Caribbean after the advent of admixture.

1Three migration models were tested for each admixed population: a simple model of single pulses of migrants from each source population, beginning with Europeans and Native Americans at T1 followed by African migrants at T2 (EUR,NAT+AFR); the simple model followed by an additional pulse of European migrants (EUR,NAT+AFR+EUR); the simple model followed by an additional pulse of African migrants (EUR,NAT+AFR+AFR). Log likelihoods given either model were compared and we present the model with the best Bayesian Information Criterion (log likelihood values in bold).
2The maximum likelihood estimate of time since admixture initially began. We assume prior migration between the populations was zero. Time since migration began is indicated in generations.
