Exploring the Miller-Urey Experiment and the Origin of Life

The video explores the Miller-Urey experiment, which simulated early Earth conditions to test the hypothesis that life could arise from non-living matter. It begins with the disproof of spontaneous generation and discusses Darwin's evolutionary theory. Oparin's idea of a primordial soup is introduced, leading to the Miller-Urey experiment, which demonstrated that biomolecules could form under ancient Earth-like conditions. This experiment marked a pivotal moment in science, transforming speculation into testable science and giving rise to prebiotic chemistry. The video concludes by highlighting ongoing research inspired by this experiment.
