I've attached a few websites that may be helpful, but I think you will have a difficult time finding what you want on line.  A textbook might be a more likely solution.

Shyguy is right.  It is called a phylogenetic diagram (or tree).  It is theorectical, based upon genetics and is a major part of cladistic analysis.\nAn older term is the Tree of Life and it is based upon the differences in the physical characteristics of life forms, allowing one to classify an individual specimen as a specific plant or animal.

Sure.  Start with this link.  And please don't cry. :-)\n\nAdded:  First of all, all an org chart is a a visual representation of the information supplied in the link I gave you.  You could create one yourself.  Secondly, I found no such organizational chart on the Internet.\n\nBe creative and make your own, for goodness sake!

Try Google or Yahoo.  You'll find worked examples there.  I think it needs diagrams to understand; they and the accompanying explanations are too complex to attempt to reproduce here.

These references would be a good start.  Really, any old organic textbook would be the best.
