  text: Speciation is a key evolutionary process that is not yet fully understood.
    Combining population genomic and ecological data from multiple diverging pairs
    of marine snails (Littorina) supports the search for speciation mechanisms. Placing
    pairs on a one-dimensional speciation continuum, from undifferentiated populations
    to species, obscured the complexity of speciation. Adding multiple axes helped
    to describe either speciation routes or reproductive isolation in the snails.
    Divergent ecological selection repeatedly generated barriers between ecotypes,
    but appeared less important in completing speciation while genetic incompatibilities
    played a key role. Chromosomal inversions contributed to genomic barriers, but
    with variable impact. A multidimensional (hypercube) approach supported framing
    of questions and identification of knowledge gaps and can be useful to understand
    speciation in many other systems.
