How many animals are self aware?

This is a very complex question and there's no easy answer. There's no scientific consensus on what constitutes "self-awareness" and how to definitively measure it.

Here's what we know:

* We can't definitively say how many animals are self-aware. There are many different interpretations of self-awareness, and the criteria used to define it can vary widely. Some consider it the ability to recognize oneself in a mirror, others focus on complex social interactions, and others on problem-solving skills.

* Some animals exhibit behaviors that suggest self-awareness. For example, chimpanzees, bonobos, and orangutans have shown the ability to recognize themselves in mirrors. Elephants, dolphins, and even some birds have demonstrated complex social behaviors that might be considered self-aware.

* Research on animal self-awareness is ongoing. Scientists are constantly learning more about animal cognition and behavior, and the field of animal consciousness is an active area of research.

It's important to remember that attributing human-like consciousness to animals can be misleading. We need to be careful about drawing conclusions about animal self-awareness based solely on our own human experiences.

Ultimately, the question of how many animals are self-aware is still open for debate and further investigation.
