Culture refers to what has been grown and groomed by humanity, in contrast to nature which refers to what grows organically. Language, culture, and humanity's relationship with nature are inextricably linked. As human cranial capacity increased over 200,000 years ago, it allowed for greater developments in technology, language, and social organization. Language was a crucial development that enabled humans to conceptualize, acquire knowledge, develop meaning, and express ideas, which in turn fed the development of culture through learning and transmission between individuals and groups. Culture represents humanity's way of constructing meaning and reality through our relationship with the natural world.
