The history of research involving human subjects includes instances of unethical practices and, consequently, the advent of guidelines and regulations to ensure the protection of human subjects’ participation in research. Prepare a one- to two-page report (single-space, excluding references) on the major milestones in the history of ethical issues in research. Include at least 3 milestones. A milestone can be an unethical research event or a regulation guiding research with human subjects. For each milestone write a brief paragraph.
