In the early development of human life on earth, three important steps that were taken are as follows: First, the development of tools enabled human beings more effective control over their environments. Second, the formation of a recognizable and intentional social and political structure served as a powerful stabilizing force for humankind. Third, agriculture provided still more stability for human societies while also ensuring (to a great, if not complete, extent) future growth and additional civilizational developments.
