Geochemistry to Biochemistry—Raw Materials

Lecture no. 26 from the course: The Origin and Evolution of Earth: From the Big Bang to the Future of Human Existence

Geochemistry to Biochemistry—Raw Materials

Taught by Professor Robert M. Hazen | 31 min | Categories: The Great Courses Plus Online Science Course

Investigate the problem of defining life, focusing on the organic raw materials from which life must have begun. Learn that these materials are surprisingly common across the universe. Finally, look at the recent discovery of extremophiles and the implications for the existence of life on other worlds.
