If you have enjoyed watching Your Inner Fish or Cosmos on television recently, you might enjoy this book. The author of Your Inner Fish combines cosmology, geology, paleontology, and evolutionary biology in a history of our planet and how all life is connected. His writing is accessible, informative, and often engaging, especially when he describes fossil hunting in Greenland and elsewhere. The formation of the planets, our moon, continental drift, ocean rifts and volcanoes, and even photosynthesis contributed to our biology. Why is hydrogen, the most common element, so important? When and why did mammals develop color vision? The discoveries of several scientists are described, along with the difficulties they had in having their discoveries accepted.
