Population divergence time estimation using individual lineage label switching
G3: Genes, Genomes, Genetics, 2022 Divergence time estimation from multilocus genetic data has become common in population genetics and phylogenetics. We present a new Bayesian inference method that treats the divergence time as a random variable. The divergence time is calculated from an
