The Smartest Animal in the World
Chimpanzees are the smartest animals in the world. Chimpanzees, also called chimps, are the only animals that can learn American Sign Language. Oftentimes, chimps use sign language as a way to communicate back and forth with humans. They can even remember the sign for a person's name! They are known to tackle difficult math problems and to solve advanced scientific equations. Chimpanzees are usually found in wet areas with warm climates such as tropical rainforests, wetlands, or savannas. Though they spend some of their time playing in the treetops, you're more likely to find one on land, collecting branches and twigs to build their nests where they sleep.
