Philosopher: Wolves do not tolerate an attack by one wolf on another if the latter wolf demonstrates submission by baring its throat.
Conclusion
You can't say that "animals don't have rights" based on the notion that "only humans can obey moral rules".
Evidence
Foxes, dogs, and wolves all follow a rule that .
Evaluation
We just need to describe the type of evidence or type of move the author made. The author supplied a specific example of a non-human animal that appears to follow some sort of moral rule, in order to make a very general conclusion. The author's conclusion isn't saying that animals do or don't have rights; it's saying you can't argue that animals don't have right based on the notion that animals can't follow moral rules ... because I just showed you an example of animals following moral rules.
Goal
Look for an answer that describes the conclusion as rejecting an argument or rejecting the basis for a certain general conclusion, and that describes the evidence as a specific example that seems to contradict that basis.
