Final answer:
The true statement about human language is that it is dynamic and evolves over time. It has a complex system of rules and is influenced by social interaction and culture, reflecting the continuous adaptation and cognitive abilities of human society.
Step-by-step explanation:
Human Language Dynamics.Among the options provided, the statement that is true about human language is D. Human language is dynamic and evolves over time. Language is not static; it changes as societies evolve and adapt to new conditions. Language is an intricate system of communication involving a lexicon and grammar rules uniquely enabling humans to convey abstract and nuanced information. It influences and is influenced by social interaction and the cultural environment. Though all human languages share some commonalities due to our shared cognitive abilities, no two languages have the same grammatical structure. Furthermore, while human language does employ visual components such as written alphabets and sign language, it is primarily a verbal communication system. Thus, saying that human language is primarily visual (option C) is not accurate.
Language not only enables communication about the immediate and observable but also allows for the discussion of complex and unseen matters. The natural acquisition of language during early childhood illustrates its inherent, dynamic quality and role in cognitive development. This process follows a predictable sequence globally, suggesting the presence of a biological predisposition towards language acquisition, which aligns with the evolution of human communication abilities. Language development and the cognitive abilities associated with it are a central part of what makes human culture and our ability to adapt so distinct.
