The only 'documentation' that we have come from fossils. You can't really actively observe evolution, because it is unfathomably slow. It typically takes millions of years. Soleron did a wonderful job of explaining it. We can, however, see some changes in populations in species that have very fast generational periods. One example is fruit flies, and this is why so many genetic tests are done with fruit flies.

The observational evidence you seek comes from the fossil record.
