When the researchers compared the human ultraconserved element to all the DNA sequences in the public database GenBank, the closest match was to DNA from the coelacanth -- an ancient fish thought to have gone extinct millions of years ago until a live specimen was caught in 1938 off the east coast of South Africa.

该鱼类一度被认为已经绝种,直到1938年在南非的东海岸又重新被发现。腔棘鱼是一种3亿6千万年海洋生物向陆地脊椎动物进化过程中至关重要的鱼类的后裔。虽然人类和腔棘鱼的演化从那时就分道扬镳,然后经过百万年的演化人类和腔棘鱼仍然共享着类似的重要基因片断。

Researchers expected that the gene responsible would vary from lake to lake. Instead, they found that each group of stranded sticklebacks had lost its armor by the same mechanism: a rare DNA defect affecting a signaling molecule involved in the development of dermal bones and teeth. That single preexisting variant--rare in the open ocean--allowed the fish to adapt rapidly to a new environment.

研究者希望不同的湖之间相关的基因有所差别,可是,他们发现每一组搁浅的棘鱼都通过同样的机制失去了它们的装甲:一种罕见的DNA缺陷影响了一个涉及皮内骨和牙齿生长的信号分子,这一个先前存在的变数——在开放的海洋中很少存在——使得鱼可以迅速适应新的环境。
