Macro vs. Micro Evolution Macro vs. Micro Evolution by David Skjaerlund Charles Darwin sparked a revolution in scientific thought with the publication of his book, The Origin of Species, in 1859. His discovery of the several different types of finches on the Galapagos Islands with similar characteristics, derived from a common ancestor, comprised his evidence for micro-evolution. They were each very different, yet closely related. He used the evidence from the first half of his book on micro-evolution to suggest that the same mechanism could produce all life forms. However, this concept of macro-evolution is not supported by modern scientific evidence.
Species do vary and change, but only on a small scale.
We have many examples of Darwin's finches and even the breeding history of dogs which supports the notion of micro-evolution. Micro-evolution was first understood when George Mendel demonstrated the variation within species based on genetic mechanisms. By Mendelian genetics we see the various dog species, which range from the St. Bernard to the chihuahua. In other words, it is accepted in scientific circles that all the different types of dogs most likely descended from a common canine ancestor. Evolutionists, however, have expanded the model to suggest the origin of the universe, the origin of life from non-life, the origin of amphibians from fishes, the origin of birds from reptiles, and so on.
