Final answer:
Running, speaking, and writing depend on minerals like calcium, magnesium, potassium, and sodium, which are crucial for muscle contractions and nerve impulse transmissions. Cognitive functions linked to these activities also played a role in the development of human language and culture.
Step-by-step explanation:
The ability to run, speak, and write depends on the availability of minerals essential for various bodily functions that perform these activities. Calcium and magnesium contribute to muscle contractions required for running. Similarly, for speaking and vocalizing, the coordination of lungs, vocal cords, and articulation muscles are supported by electrolytes like potassium, calcium, and sodium. When it comes to writing, the fine motor skills involved in gripping and moving a writing instrument require the precise function of muscles and nerves, which rely on minerals such as calcium, potassium, and sodium to transmit nerve impulses and facilitate muscle contractions.
Therefore, the intricate cognitive functions behind planning and executing complex speech or using tools are believed to have enabled the development of human language and culture, as indicated by advances in tool-use and cognitive planning in early hominins like Homo habilis and Homo erectus. These processes are also critical for the evolution of symbolic language and the emergence of human culture.
