"Dogs"

Any animal is divided into two modes of memory: short-term memory and long-term memory, where short-term memory is something that is stored in the animal's brain for only a few seconds, usually such things are arbitrary events for the animal.

In the wild, wolves are pack animals, and by living in packs they stand at the top of the food chain, but despite this, they face daily threats

Under human domestication, people are more like the head wolf of the pack in the eyes of dogs, and when people are alive, they are absolutely loyal. However, when the "head wolf" dies, this obedience disappears, so there is no difference between the human corpse and the meat of animals in nature in front of the dogs

This phenomenon could not be detected through traditional dietary research methods, but by using DNA-based techniques, such interactions were revealed for the first time, leading to important questions about how human activities affect wildlife.
