From childhood to old age, the fear of the unknown affects people in many different ways, but most obviously in certain situations, such as being out at night or in a strange place. This fear is common to all animals, including humans, and seems to have been connected with survival in evolutionary history. An animal that is wary of strange and unknown situations is more likely to avoid danger than one that rushes headstrong into every new experience.
从童年到晚年，未知的恐惧以许多不同的方式影响着人们，但在某些情况下显然更为明显，例如在夜晚或陌生的地方出现。这种恐惧是所有动物，包括人类的共同特征，似乎与生物进化史上的生存相关。一个对陌生和未知情况保持警惕的动物比那些冲入每一个新体验的动物更有可能避免危险。
