It happens to some of our phylatic cousins, because if you're a monkey, and you look at another monkey, and that monkey has a higher hierarchy position than you, and that is considered to be a signal or threat, well, you are not going to be alive for long.
对于我们进化上的远亲,也是如此 如果你是一只猴子 你正在看着另一只猴子 另一只猴子比你的等级更高 如果这被看成是一种信号或威胁, 你是不会活很久的
