Over an estimated 10,000 generations, the sticklebacks show structural differences that are greater than those seen between different genera of fish including variations in fins, changes in the number or size of their bony plates, variable jaw structure, and color differences.
估计已经有10000世代了，三刺鱼表现出的结构性差异大于我们看到的不同属的鱼类之间的差异，包括鳍的不同，骨板的数量或大小出现变化，可变的颌骨结构以及颜色的差异。

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。
