Human vs Animal Communication

Both humans and animals communicate, but there are fundamental differences between human language and animal communication systems. Understanding these differences helps us appreciate what makes human language unique and how animal communication systems (like bee dances) compare.

Properties of Human Language

Linguist Charles Hockett (1960) identified several design features of human language that distinguish it from animal communication:

1. Semanticity

Words and sentences have specific meanings that are understood by both the speaker and listener. The word "dog" refers to a specific type of animal, and speakers of English share this understanding.

2. Displacement

Human language allows us to talk about things that are not present — events in the past, plans for the future, imaginary scenarios, and places we have never visited. We are not limited to communicating about the "here and now."

3. Productivity (Creativity)

Human language is infinitely productive — we can create and understand sentences that have never been said before. There is no limit to the number of new, meaningful sentences we can produce.

4. Cultural Transmission
