Document Summary
Chapter 5: the nature of life on earth. Cells of different purpose and nature are spread throughout your body non-randomly, performing tasks in an ordered manner. Order alone fails to categorize life, as order can be found in books, crystals, clocks, roads and more. Cell division (almost exact copy), sex (semi-random combination of genetic codes) Insufficient for life: a mule is the offspring of a horse and a donkey. Mules are sterile and cannot reproduce (yet are a product of reproduction. ) Viruses: incapable of reproduction on their own. Infect a host to utilize their cellular machinery for reproduction: growth and development livings grow and develop in patterns directed by heredity, the passing of traits from parent to offspring, regardless of reproductive pathology. Insufficient for life: while all life seems to go through a phase of growth and development, so too does a fire, which grows and develops as it consumes fuel in a house or forest.
