在最新版的自然通讯杂志上,他们发表了他们的结论,标志着25年的研究工作到达了定点。
‘This study caps questions in developmental and evolutionary biology, popularly called “evo-devo” that I've been interested in for 35 years,’ said Willy Bemis, Cornell professor of ecology and evolutionary biology and a senior author of the paper.
“这项研究覆盖了我已经研究了35年的发展与演化生物学上的问题”,康奈尔大学生态学和生物进化学的教授维利·彼米斯说。
He explains that hundreds of millions of years ago, there was a major split in the evolutionary tree of vertebrates.
他解释在几百万年前,在脊柱动物的进化史上有一次主要的改变。
One lineage led to the ray-finned fishes, or actinopterygians, and the other to lobe-finned fishes, or sarcopterygians.
一种进化成为了鳍刺类鱼,一种进化成了总鳍类鱼。
The latter gave rise to land vertebrates, some of which, such as the Mexican axolotl salamanders, retained electrosense ability.
后者是陆地脊柱动物的祖先,他们当中的一些还保持着探测电磁场的能力。
Some ray-finned fish, including paddlefish and sturgeon, also retained these receptors.
一些鳍刺类鱼,包括白鲟和鲟鱼,也有这样的探测神经。
Professor Bernis and his team found that the electrosensors of the ray-finned fish and the salamander developed in precisely the same pattern from the same embryonic tissue in the developing skin, confirming that this is an ancient sensory system.
