Cephalopods have recently moved into the research focus due to the growing number of sequenced genomes, molecular tools, and laboratory culture (Albertin & Simakov, 2020). Genome data now allows us to ask how the many known novelties of cephalopod morphology are reflected in their genomes and gene regulation. A crucial gap in this understanding has been the limited information for the Nautilus, the last survivor of a cephalopod lineage that diverged from the highly derived coleoid clade (octopus, squid, cuttlefish) around 400 million years ago. The publication of Nautilus genomes (in this issue of Molecular Ecology [Huang et al., 2021; Zhang et al., 2021]) will help us understand which genetic changes happened when, and ultimately how they contributed to cephalopod evolution.
由于已测序基因组数量的增加、分子工具的发展以及实验室培养技术的进步,头足类动物最近已成为研究热点(阿尔贝廷和西马科夫,2020年)。基因组数据现在使我们能够探究头足类动物形态学中众多已知的新奇特征是如何在其基因组和基因调控中体现的。在这一认识过程中,一个关键的空白在于对鹦鹉螺的了解有限,鹦鹉螺是头足类动物谱系的最后幸存者,该谱系在约4亿年前从高度特化的鞘亚纲分支(章鱼、鱿鱼、乌贼)中分化出来。鹦鹉螺基因组的发表(本期《分子生态学》[黄等人,2021年;张等人,2021年])将有助于我们了解哪些基因变化在何时发生,以及它们最终如何对头足类动物的进化产生影响。
