Biology 1001 19:19 DNA is the Molecule of Heredity If the DNA replication makes one era (1 in a million), 3 billion need to be replicated;  there will be 300 million eras. The coping process is not perfect, although highly  accurate.  Living things as a whole have the capacity to evolve Things evolve over generations  Mutation is what allows different species to evolve over those generations.  Natural selection is a process where organisms with certain adaptations survive and  reproduce more successfully than others.  Categorizing Life Organisms can be grouped into 3 Domains.  Bacteria-Single, simple cell  Staff infection, Acne Unicellular  Prokaryotic Some photosynthesize-make own food, most absorb food from surroundings.  Single Cell divides into 2 cells showing growth.  They can divide every 20 mines, if they have food (optimal)  Archaea- single, simple cell; extremes  Most live in extreme environments like salt water that is 10 xs saltier than the ocean.  Eukarya- one or more highly complex cells Contains 4 domains
