The course explores the theory of evolution from the "primordial soup" to the modern era, followed by more relevant exploration of key biological systems and the idea of biodiversity and communities. There's some imbalances in the attention given between one topic and another, and it focuses a lot of some extremely specific processes and skims through others.
If you're germophobic, this is a book you might want to skip. It explains the origins of microbes and how they spread, along with their evolutionary threats and potential epidemics. Terrifying, but I couldn't put it down.
This is one course that makes me want to listen to more courses by Professor Hazen. While I don't subscribe to some models he explains, it provided me with an alternative possibility of the history of the Earth.
