title: Data from: Transitions between phases of genomic differentiation during stick-insect speciation

description: Speciation can involve a transition from a few genetic loci that are
 resistant to gene flow to genome-wide differentiation. However, only
 limited data exist concerning this transition and the factors promoting
 it. Here, we study phases of speciation using data from &gt;100
 populations of 11 species of Timema stick insects. Consistent with early
 phases of genic speciation, adaptive colour-pattern loci reside in
 localized genetic regions of accentuated differentiation between
 populations experiencing gene flow. Transitions to genome-wide
 differentiation are also observed with gene flow, in association with
 differentiation in polygenic chemical traits affecting mate choice. Thus,
 intermediate phases of speciation are associated with genome-wide
 differentiation and mate choice, but not growth of a few genomic islands.
 We also find a gap in genomic differentiation between sympatric taxa that
 still exchange genes and those that do not, highlighting the association
 between differentiation and complete reproductive isolation. Our results
 suggest that substantial progress towards speciation may involve the
 alignment of multi-faceted aspects of differentiation.
