M. emersoni populations have been isolated from each other over the last 200,000 years and modern population structure reflects geography. a Simulations showing approximate timing of isolation events between M. emersoni populations in the Arizona Sky Islands during the last 200,000 years (see also Additional file 1: Figure S2). These simulations revealed two geographical groupings of Sky Islands: North and South. b Redundancy analysis showing that most of the mtDNA genetic variation is explained by geography (site). The Venn diagram represents the percentage of the genetic variation that can be attributed to each factor (circles) or their combined effect (overlapping areas). This analysis supports the hypothesis of multiple origins of the wingless phenotype, where genetic variation is structured by geography rather than habitat, phenotype or elevation (see also Additional file 1: Figure S3 and S4)
