Dan Crocker: Join me as we discuss one of science’s greatest mysteries: how did life originate on Earth? We will discuss the chemical ingredients that are necessary for life, and will travel back in time to explore how these ingredients may have formed on early Earth. We will discuss whether rocks from outer space may have contributed to the development of life on Earth and how scientists have progressed toward answering this question.
