Trace the evolution of a chosen profession, field of study, or branch of service, during the eras of American History. For some, this may mean looking at the technology or opportunity that would evolve from as far back as the 1860s into what is used today. Be sure to follow the themes of the Market, Transportation, and Technological Revolutions and describe how necessity would breed innovation; also, highlight how events, like reform, war, economic, and progress may have directly impacted your profession. Your final product should be a minimum of 500 words. To complete this assignment, a minimum two (2) reputable sources must be used, cited, and referenced. Encyclopedias (online or print), message boards, or any source that can be amended without educated review are not considered appropriate. Failure to use appropriate resources can lead to deductions.
