Koko, the famous gorilla born in 1971, amazed the world after learning more than 1,000 signs in sign language and understanding nearly 2,000 spoken English words. Under the care of psychologist Francine Patterson, she became one of the most intelligent animals ever studied. 🦍✨

But what moved millions the most was her emotional sensitivity. Koko formed a deep bond with a small kitten she personally named All Ball and, when the cat died, she reacted with clear signs and sounds of sadness, leaving both scientists and the public heartbroken. 💔

Although some experts questioned whether her abilities were simply learned responses, Koko ultimately became a global icon and, even after her death in 2018, she continues to be remembered around the world. 🥹❤️
