Intelligence in animals refers to their ability to learn, solve problems, and adapt to their environment. Different species exhibit various forms of intelligence, such as tool use in crows and chimpanzees, or social intelligence in dolphins and elephants. These abilities help animals find food, communicate, and navigate their surroundings. Research shows that intelligence is not limited to mammals; octopuses demonstrate remarkable problem-solving skills, while parrots can mimic human speech and understand complex commands. Understanding animal intelligence helps scientists learn more about evolution and the cognitive abilities shared across species.
