Final answer:
Morse Code is not an ancient writing system; it was developed in the 1830s. Ancient civilizations used writing systems such as hieroglyphics and cuneiform. The Maya developed the first known writing system in the Western Hemisphere. B) Maya civilization
Step-by-step explanation:
The writing system that was not used by ancient civilizations is C) Morse Code. Ancient civilizations such as those in Egypt and Mesopotamia developed complex writing systems like hieroglyphics and cuneiform, respectively. The Sumerians are credited with developing cuneiform, characterized by wedge-shaped symbols, around 3400 BC in southern Mesopotamia. This system began as pictographs and evolved into a more phonetic script where each symbol represented a syllable. The Egyptians developed their own unique system known as hieroglyphics around 3000 BCE, which combined alphabetic signs, syllabic signs, word signs, and pictorial representations.
Morse Code, however, is a modern method of encoding text messages in a series of long and short sounds or visual signals, and was developed by Samuel Morse and Alfred Vail in the 1830s, far removed from the time periods of ancient civilizations.
Additionally, the earliest known Western Hemisphere writing system was developed by the B) Maya civilization, who were one of the pre-Columbian cultures in Mesoamerica.
