“…The species used as the experimental materials include human, mouse, rat, marmoset, dog, pig, ferret, hamster (cultured cells), Xenopus , Iberian ribbed newt, zebrafish, medaka, anemonefish, sea urchin, sea lily, sand roller, nematodes ( Caenorhabditis elegans and Pristionchus pacificus ), planarians, and Arabidopsis thaliana . We believe that this special issue facilitates the development of the cross‐species research platform and reveals the mechanisms generating the diversity of life on Earth, as we wrote in the preface at the start of this special issue (Ogino et al, 2021).…”
