很多人天生就怕蛇或蜘蛛(zhi1 zhu2)，这是什么原因呢？它们并没有给过这些人同年阴影，可是为什么人们就是这么怕它们呢？

“The idea is that throughout evolutionary history, humans that learned quickly to fear snakes would have been at an advantage to survive and reproduce,” said Vanessa LoBue, a post-doctoral fellow in psychology at the University of Virginia. “Humans who detected the presence of snakes very quickly would have been more likely to pass on their genes.”

人们不是天生怕蛇，可以说是学会怕蛇。科学家推测怕蛇的性格导致人类能够继续生存以及繁殖。虽然蛇不是满地爬，不过人类能够把周围的东西当作蛇的影像，进而提高警觉。蛇对人类的进化做出了很大的贡献。或许很多很多年以后，人类一看到枪也能够马上躲避。可能还会进化出躲开子弹的超能力呢。
