The term 'LEMURS AND US' is a reference to the scientific classification of PRIMATES, which includes humans and lemurs. Lemurs are a type of primate that are native to Madagascar and the surrounding islands. They are known for their large eyes, long tails, and distinctive vocalizations. Humans are the most advanced of the PRIMATES, with the ability to use tools, communicate through language, and develop complex societies. Both lemurs and humans are classified as PRIMATES, making them closely related species.
