If you are interested in biology, evolution and the story of our planet. How did the life evolve in the early begining? You learn that the Gunflint formation near Grand Portage contains one of the oldest fossils: 1.9 billion years. A good chapter on the martian meteorite and how the scientists conclude that it doesn’t contain fossils. Other masterpiece in the same domain: check A. Knoll’s book (life in an early planet).
