Which of the following experiments helped support hypotheses about the origin of life?

Fox's protocell experiment is pivotal in supporting hypotheses about the origin of life because it demonstrated how simple organic molecules could organize into more complex structures that resemble early cellular life, known as protocells. In his experiments, Fox created vesicles that encapsulated compounds, mimicking the behavior of cell membranes. This suggested that life could have originated from simpler forms through natural processes, contributing to our understanding of abiogenesis, the process by which life arises naturally from non-living matter.

The experiment aligns with the hypothesis that life began from simple organic compounds in the primordial environment, evolving over time into more complex forms. By showing the potential pathways for the formation of cellular structures, Fox's work offers vital insights into how the first living organisms might have emerged on Earth.
