Gender equality is not a consequence of early civilization
Step-by-step explanation:
Early civilizations include the civilization in Sumeria, Mesopotamia, Porto Chico in South America, Indus river valley civilization and the Chinese civilization.
None of these societies had, as far as it is known, equality for women to men.
Thus, gender equality is not a product of those early societies as it continues to be a problem until the modern age and the inequality of gender probably did begin around the time of domestication of humans and division of labor.
