What is most like a monkey?

That's a tricky question! It depends on what aspect of a monkey you're interested in. Here are some possibilities:

Physical appearance:

* Apes: Chimpanzees, gorillas, and orangutans are the closest living relatives to humans and share many physical similarities with monkeys.

* Other primates: Lemurs, lorises, and tarsiers are all primates, though they might not look as similar to monkeys as apes do.

Behavior:

* Other social animals: Many animals live in social groups, like wolves, dolphins, or even some birds. They might show similar social dynamics to monkeys.

* Other playful animals: Many animals, like puppies or kittens, are known for their playful nature. Monkeys are also very playful, so these animals share that characteristic.

Intelligence:

* Other primates: Chimpanzees, bonobos, and gorillas are known for their complex intelligence and problem-solving abilities, which are comparable to monkeys in many ways.

* Cetaceans: Dolphins and whales are also highly intelligent creatures, capable of complex communication and tool use.

Ultimately, the answer depends on your definition of "most like a monkey." You need to be more specific about which aspects of a monkey's life you are interested in to get a more accurate answer.
