Selective breeding ofdomesticated plants and animalshave results that are similar tolaboratory experiments andsometimes go beyond what is seenin nature.The gradual evolution of cornthrough selective breeding byNative Americans is recordedin archeological sites, in afashion similar to the recordof the evolution horses, etc.,recorded in fossils.10
Natural selection has been documented in nature many times.In Galapagos finches, available seed sizes change with differentamounts of rainfall. Dry years result in more large seeds. Wetyears result in more smaller seeds. Studies of reproductivesuccess in finches indicate that large-billed birds have higherfitness in dry years, and small-billed birds have higher fitness inwet years. Fitness is reflected in the offspring produced duringwet and dry years. The pattern is repeatable and predictable.11
