An example of evolution is when scientist study the fossil-record and studying the genetics of living organisms dating back to around 3 and 1/2 billion years ago.

A more modern definition is: change in genetically determined characteristics of populations. The process is driven by natural selection. A classic example is that of the Peppered Moth (Biston betularia) of Britton.

Posted by versatilekamini on Wednesday December 16, 2009 at 4:45 AMCharles Darwin’s name is closely associated with the concept of evolution and for many people Darwinism is evolution. The explanation of evolution has been beautifully elaborated by Darwin in his book entitled “The Origin of Species by Natural Selection.” Examples of evolutions are: vestigial organs like vermiform appendix in man, muscles of external year, vestigial tail vertebrae, wisdom tooth, and evidences from paleontology like Archaeopteryx.
