All animals have instincts. They're born with natural abilities to do certain things. Wild animals also learn by copying their parents and practicing. And pets learn through training. But instincts and training aren't the only keys to animals' behavior.

Animals often make choices, plans, and sensible changes. They can help others and solve problems. A gorilla born in captivity has helped answer that question. Koko was taught to use sign language. Koko once had a pet kitten she named All Ball.
