Using excerpts from Michener’s books, he writes segments about the animals that were included in the larger stories. This is a wonderful history of the changes of the Earth through the centuries – the development of land and water features and the beginnings of the animal kingdom – from small to huge, back to medium size, and the coming of man. Description of each section is so full of information that the reader feels like he/she is actually there, watching the events happening and understanding the feelings of the animals. One adventure follows two men and a hyena as they explore Africa as friends. Others told about the lives of a mastodon, an ancesstral bison, a crab, a dinosaur, a salmon, armadillos, the comparison of two hunting dogs – a labrador and a chesapeake – by their competing owners, and several other animals. All had names and personalities. I learned so very much about these animals as their stories were told. The last story is told by the author as he visits an old friend who was trying to protect his bird feeder from an invading squirrel, but unwilling to endanger the pest. The squirrel was in no danger.
