Qualities Defining Language
📌 Language is often characterized by four specific qualities: discreteness, grammar, productivity, and displacement.
🧩 Discreteness involves combining individual units (like sounds or words) to communicate new ideas, similar to rearranging poetry magnets.
📜 Grammar provides the rules for combining these discrete units effectively.
♾️ Productivity is the capacity to generate an infinite number of novel messages using a finite set of elements.
🗺️ Displacement allows communication about things not immediately present, such as past, future, or fictional events.

Animal Communication vs. Language
🦀 Crabs and cuttlefish communication lacks discreteness and grammar and only addresses current conditions (e.g., "I am healthy").
🐝 Honeybees exhibit displacement through their waggle dance, conveying the location and richness of food sources outside the hive.
🐕 Prairie dog alarm calls are highly specific, indicating a predator's size, shape, speed, and even features like whether a human predator is carrying a gun.
🦍 Great apes, like Washoe (chimpanzee) and Koko (gorilla), demonstrated discreteness (creating original phrases) and displacement when using human-taught sign languages.

Uniqueness of Human Language
🧠 Human language's distinctiveness lies in the powerful combination of grammar and productivity, coupled with discreteness and displacement.
🗣️ Humans can create and understand complex sentences and words never spoken before.
😂 Human language enables communication across an endless range of subjects, including imaginary concepts and the ability to lie.
⚖️ While some animals show *some* language properties, none display all four naturally, and the complexity achieved by great apes is outpaced by most three-year-old humans.

Key Points & Insights
➡️ Animal communication systems, while sophisticated (e.g., dolphin whistles identifying names/gender), generally do not display all four core qualities of language naturally.
➡️ The key differentiators setting human language apart are the robust ability to use grammar to structure an infinite productivity of messages.
➡️ Future research suggests human language and animal communication might exist on a continuum rather than being entirely separate entities.
