Speciation is a continuous process driven by barriers to gene flow. Based on genome‐wide SNPs (single nucleotide polymorphisms) of 190 toads from 31 sampling sites of Scutiger boulengeri complex, we found evidence for monophyly which represented a continuous speciation process of at least six lineages in S. boulengeri , which radiated and exhibited varying degrees of divergence and gene flow. The SNP‐based phylogenetic tree wa...
