Final answer:
Determining what constitutes a language is crucial for understanding human cognition, social interaction, and cultural identity. Language, as a unique form of human communication, shapes our thinking patterns and self-perception. The study of language evolution and diversity fosters cultural understanding and helps in language preservation.
Step-by-step explanation:
Understanding what makes a language distinct from mere systems of communication is important because language is integral to human identity and social interaction. While both animals and humans use communication to convey information, human language is unique due to its complexity and ability to express abstract concepts.
Moreover, language is closely linked to how we perceive ourselves and the world around us. In various contexts, like writing an essay or having a conversation, we use language differently, shaping our identity and interactions accordingly. The evolution of language reflects and influences cultural and social developments, evidenced by the ongoing speculation about the origins of language and its tie to modern human behavior.
