"Contemporary Biology" reported that two groups of genes of minnows decided the trend of minnows. One set of genes controls the habit of fish to join a larger group, and the other set of genes determines how good the "swimming skills" of fish are in the formation of fish. The combination of behavioral habits and physical abilities produces a dazzling queue transformation of fish schools, which helps them avoid or defend against predators. "By gathering together, fish can feel the world in different ways."

So let's reveal that 1, the tragedy of subordinates is always caused by leaders. The most annoying thing for subordinates is to follow the worst leader.
