Human cultural evolution is generally divided into three stages. Explain how each has affected the

Earth. What will be an ideal response?


Concepts to Consider: Hunter-gatherer societies were nomadic; humans existed in small populations;
the importance of hunting declined about 15,000 years ago; impact on the environment was minimal,
although it may have included impacts on large mammals. The development of agriculture began
approximately 10,000 years ago; plants were cultivated first, then animals were domesticated;
agriculture lead to the development of more complex societies; the impact on the environment grew as
population numbers increased. The Industrial Revolution was marked by an increase in urbanization,
manufacturing, population growth, and disruption and degradation of the environment.
