These rules apply to all living creatures human or not.
Another point needing to be made about the theory of evolution is the fact that it is the most logical idea anyone has come up with to date. Almost all scientists believe in some sort of evolution, though they may not agree on all the details they all agree that evolution is the reason for mans place on earth. If speaking from the religious standpoint then you would say that God spontaneously created man from the dust of the earth. And that God then blew the breath of life into his nostrils. While this scenario is much more fascinating it is extremely hard to prove and much more unlikely. Even with all the proof pointing towards evolution the majority of the world still believes in spontaneous creation by God. The thought that man is a divine creature placed on earth to do God's bidding is unfounded. Man is the only animal marked by his thirst for blood and body mutilation. Only man has had the cannibalistic ways of pigmy tribes and scalping habits of the Indians among others. Man is also the only creature waging war on its own kind and doing everything in its power to completely annihilate its foe. These are not the ways of the natural creatures. Only man is corrupted in this sense. Wrangham and Peterson state, "That chimpanzees and humans kill member of neighboring groups of their own species is . . . a startling exception to the normal rule for animals". They go on to point out that this is especially true of adults killing adults. "Fighting adults of almost all species normally stops at winning: They don't go on to kill." (Wrangham and Peterson 155). Though some of this can be expected as of lions, wolves or hyenas. In fact most species are not equipped to kill one another such as a squirrel or a raccoon, it is much easier to just scare them away. Ancient scholars and theorist believed that anything natural is good.
