Amanda Ferencz AST 3033 Prof. Wooten Extra Credit: Chapter 26 Summary This chapter talks about the possibilities of life on other worlds. It covers the nature of life, the origin of life and the concept of communication with distant civilizations. The nature of life covers what life is. Living things all have a physical basis and that matter forms in different shapes to make life possible. Life is also based on carbon chemistry (the idea that most of a planet must be carbon-based). All living these have a unit of information that is always altered or controlled based on the location. This unit of information is handed down, generation to generation. A unit of information is held together in a human’s DNA, a collection of carbon-chain molecules. DNA is a ladder-shaped molecule that acts as an information manual on a human organism. This chapter also continues to explain how DNA molecules form and split, and how natural selection determines what species survives.
