Our manuscript describing biases in summary statistics like genetic differentiation (Fst), diversity (pi), Tajima’s D, and estimates of theta, migration rates, and divergence times when not accounting for ghost gene flow is now published in G3! We establish theoretical expectations for summary stats, use a gamut of simulations (shoutout to msprime + tskit) under the island, and isolation with migration models, & genomes from Native African hunter-gatherers, in this multiyear effort from my grad students Melissa, Michael, and Margaret - congratulations to all of them!
