Biochemical Theory of Origin of Life & Miller-Urey Experiment | GRADE 12 Biology | New Curriculum

In the first 15 seconds, you will learn where the first cell came from and how scientists explain the origin of life through the Biochemical Theory. This lesson from the New Ethiopian Curriculum textbook teaches Grade 12 Biology students the Biochemical Theory of Origin of Life, including the contributions of Oparin and Haldane, the formation of organic molecules, and the famous Miller-Urey experiment. The topic is highly important for the Ethiopian University Entrance Exam (EUEE), school exams, and biology revision.
