最近，美国的一组科研人员发现，一种发生了基因突变的斑马鱼特别喜欢冒险，面对它的捕食者，它不像正常的斑马鱼那样马上逃避掉，而是勇敢地向危险的敌人游去。 科研人员将小木棍伸到水中去戳斑马鱼，正常的斑马鱼马上就游走了，而一种发生了基因突变的斑马鱼却兴奋地 围着小 Recently, a group of researchers in the United States found that a zebrafish that has undergone a genetic mutation is especially adventurous. In the face of its predators, unlike the normal zebrafish, it does not flee immediately, but instead bravely gives the dangerous enemy Go tour. Researchers will be small sticks into the water to stamp the zebrafish, normal zebrafish swim immediately, and a genetic mutation in zebrafish but excited around the small
