Answer 1

Answer:

Some nonhuman animals, including chimpanzees, orangutans, and perhaps dolphins, have at least a primitive sense of self (Boysen & Himes, 1999). We know this because of some interesting experiments that have been done with animals. In one study (Gallup, 1970), researchers painted a red dot on the forehead of anesthetized chimpanzees and then placed the animals in a cage with a mirror. When the chimps woke up and looked in the mirror, they touched the dot on their faces, not the dot on the faces in the mirror. This action suggests that the chimps understood that they were looking at themselves and not at other animals, and thus we can assume that they are able to realize that they exist as individuals. Most other animals, including dogs, cats, and monkeys, never realize that it is themselves they see in a mirror.
