The paper estimates speciation clocks in Caenorhabditis nematodes, finding post-zygotic reproductive isolation accumulates faster than pre-zygotic isolation.

This study identifies multiple developmental defects in hybrids of Caenorhabditis species that contribute to postzygotic reproductive isolation, but finds no evidence of premating isolation or ectopic sperm migration as barriers.
