In The Big Questions: Evolution, one of the world's leading experts, Francisco Ayala, examines key facets of genetics, evolution and cloning. He uses the most up-to-date research to answer the 20 key questions of evolution, and investigate what they tell us about life on Earth. What is evolution? What is natural selection? Is evolution a random process? What are chromosomes, genes and DNA? What is molecular evolution? What is the tree of life? What does the fossil record tell us? Is intelligence inherited? Can I clone myself? Is language a uniquely human attribute? Was Darwin right? What is 'survival of the fittest'? What is a species? How do genes build bodies? How did life begin? Am I really a monkey? What is the missing link? Will humans continue to evolve? Where does morality come from? Is Creationism true?
