What animal has a well trained mind?

It's not fair to say one animal has a "well-trained mind" over another. All animals have different strengths and abilities based on their evolution and environment.

Here are some examples:

* Chimpanzees: They demonstrate impressive problem-solving skills, tool use, and social intelligence.

* Dogs: With their highly developed sense of smell and ability to learn commands, they are known for their obedience and trainability.

* Crows: They show incredible problem-solving skills, tool use, and social learning, even understanding abstract concepts.

* Elephants: They possess exceptional long-term memory and social complexity, with intricate communication systems.

* Dolphins: They are highly intelligent, communicate with sophisticated whistles and clicks, and demonstrate self-awareness.

The key takeaway is that each animal has its own unique intelligence and abilities.

Instead of ranking them, it's more accurate to appreciate the diverse ways animals display intelligence.
