Hypothesis of Apis mellifera origin and dispersal routes. Solid black arrows are based on well-supported relationships inferred from Bayesian analysis of mitochondrial genomes while dashed grey arrows represent hypothetical dispersal routes. Lineage ranges are based largely on Ruttner6 and Dogantzis and Zayed20.
