1. Chimpanzees (Pan troglodytes): Chimpanzees are our closest living relatives, sharing around 98.8% of our DNA. They have a similar body structure, intelligence, and social behavior to humans but are mainly found in the forests and woodlands of Central and West Africa.
2. Bonobos (Pan paniscus): Bonobos are also closely related to humans, sharing around 98.7% of our DNA. They share many physical and behavioral characteristics with chimpanzees but stand out because of their highly cooperative and peaceful nature. Bonobos primarily inhabit the forests of the Democratic Republic of Congo in Central Africa.
