You are observing two juvenile chimpanzees. When they first meet, they embrace. They then begin tickling each other and wrestling mildly. Would you characterize this behavior as affiliative or aggressive?

Answer: Affiliative behavior

Explanation:

Affiliative behavior is the behavior in which social interaction is seen between two animals through cohesion, meeting, hugging, involvement with each other, playful acts etc. They try to display emotional and social bond between them.

According to the question, chimpanzees displaying embracing behavior, ticking and little wresting shows that they have social and emotional link with each other.

Thus, they have affiliative behavior rather than aggressive and anger-based behavior.
