Final answer:
The term that does not belong to human verbal traits is 'call systems,' as it refers to animal communication and lacks the complexity of human language features like productivity, cultural transmission, and displacement.
Step-by-step explanation:
Regarding human verbal traits, the option that does not belong is e-call systems. This is because productivity, kinesics, cultural transmission, and displacement are all features uniquely associated with human language and communication. Productivity refers to the capacity to produce an infinite number of sentences. Kinesics involves body language and gestures as part of communication. Cultural transmission is the way language and culture are passed down from generation to generation. Displacement allows us to talk about things that are not present in the immediate environment. In contrast, call systems are the forms of communication used by animals, which are typically less complex and not characterized by the same level of productivity, cultural transmission, or displacement.
