Just like humans, chimps communicate verbally and non-verbally. Their verbal communication consists of hoots, grunts, screams, pants, and other vocalizations. However, most of their communication is nonverbal; some of the expressions that scientists have discovered are of surprise, happiness, comfort and even bursts of laughter! Interestingly, Guillaume Duchenne, a French neurologist discovered that their smiles are genuine and are linked to the brain's limbic system where emotions are generated. 

Another way, in which the Chimp’s behavior is similar to humans, is the social spectrum. They laugh, smile, play, distinguish between fair and unfair and cultivate friendship. Chimpanzees spend a great deal of time socializing. Some of the practices that have been discovered are of playing, chasing and tickling both in juveniles and adults with their offspring. Too, they show affection by hugging and kissing between chimpanzees of any age or gender. Similar to humans, chimpanzees strengthen friendships by spending extensive time grooming each other and playing. It has been demonstrated, that chimps use play to build strong social relationships and develop cooperative attitudes. 

Initially, humans were considered the only tool-using animal. However, in 1960 scientists discovered that chimps use tools to solve problems. Just as humans, chimps can modify items found in their environment to create tools for their daily challenges. On the other hand, chimps can also go through stressful periods in which they turn up to social behavior for relaxation. 

All in all, the discovery of the similarities in the behavior of chimps and humans has put in question the human ancestry. Our similarity in communication, social spectrum and problem-solving is just the beginning of the DNA research humans need to find out if in fact, we are chimps. So, until scientists complete their research, we should learn from them and play when we are stressed, strengthen our relationships and hug any person of any gender.
