We used 20 de novo genome assemblies to probe the speciation history and architecture of gene flow in rapidly radiating <i>Heliconius</i> butterflies. Our tests to distinguish incomplete lineage sorting from introgression indicate that gene flow has obscured several ancient phylogenetic relationships in this group over large swathes of the genome. Introgressed loci are underrepresented in low-recombination and gene-rich regions, consistent with the purging of foreign alleles more tightly linked ...[more]
