Our paper on speciation in stick insects made the cover of Nature Ecology and Evolution (image by Moritz Muschick). In this paper we show how multiple factors come together for speciation to move from early to late stages of isolation and genomic differentiation, and we identify a distinct gap in genomic differentiation between con- and hetero-specific populations in sympatry.
