Abstract
An evolutionary hypothesis suggested by studies of the genome of the tiger pufferfish Takifugu rubripes has now been confirmed by comparison with the genome of a close relative, the spotted green pufferfish Tetraodon nigroviridis. Ray-finned fish underwent a whole-genome duplication some 350 million years ago that might explain their evolutionary success.
摘要
通过对虎河豚（Takifugu rubripes）基因组的研究提出的一个进化假说，现已通过与近亲——斑纹绿河豚（Tetraodon nigroviridis）的基因组进行比较得到证实。辐鳍鱼在约3.5亿年前经历了一次全基因组复制，这可能解释了它们在进化上的成功。
