Your all the way up to the ostrich, and I'd still like to hear the answer to how the first living cell originated.
Couldn't tell ya. The fossil record must show how it came to be, right...sorry, probably not. Ironically, all of the ostrich-like birds in the fossil record, look like some sort of form of the ostrich though. Taxonomy is not clear cut on the ostrich though. You'll have to ask a palientologist why that is.
I still don't think it can be proven either way, designed or otherwise.
