ProloguEngineerings fundamental mission to create for usershas served humanity, prehistoric humanity, and other life forms, such as insects,fish, birds, and mammals, unwaveringly for hundreds to millions of years. What distinguishes human engineering from the engineering of other life forms is the singular human capacity to envision acreation for users,then to create it and ultimately to implement it fulfilling an importantuser need.Other life forms pass down engineering creations likely leed from their prede-cessors through an evolutionary process, like creating anthills, beehives, and bird nests. Their creations are leed replications of earlier experiences more than an intellectual response to new opportunities. User advancements without opening new frontiers limit advancement of a species. The life forms above are exemplars among all the user species of engineering, but only human engi-neering leads to new creations that lead to remarkably significant user advancements.
