False. In the Americas, the Mayans created the calendar, the Aztecs had terrace farming. People from China, India, and the Mediterranean civilizations travelled to Africa to learn mathematics, science, and architecture. The term "Important developments" is subjective. What may not be important to one civilization could be of significance--a matter of life and death-- for a different civilization.
