What Does a Martian Look Like?: The Science of Extraterrestrial Life
Jack Cohen, Ian Stewart

In What Does a Martian Look Like?, two respected scientists and authors combine real science with the creations of some of the world's most inventive science fiction writers to imagine how life may have evolved elsewhere in the universe. They show that the universe is not populated with countless variations on the humanoid form or horrifying creatures drawn from your worst nightmares. Instead, they demonstrate how universal principles of life might produce amazingly diverse outcomes when applied in different environments.
