Out of Thin Air: Dinosaurs, Birds, And Earth’s Ancient Atmosphere
Thursday, September 20th, 2007
I just finished Out of Thin Air: Dinosaurs, Birds, And Earth’s Ancient Atmosphere by Peter Douglas Ward. In it, the author argues that the most powerful force in Earth’s history driving the evolution of animals is the level of oxygen in the atmosphere and in the seas. I must admit, he makes a compelling argument, and I was mostly convinced. It’s an interesting read, and is especially useful for providing an overview of animal evolution over the past 500 million years. I recommend it.
