No mr. du-mass
Im trying to teach you your own therory as apparently you dont know it.
Want to change your statement on covergent evolution and the appendix?
Read the study
http://www.sciencedirect.com/science/article/pii/S1631068312001960
It is saying that the appendix has evolved in different species, yes, but you are interpreting this sentence wrongly. It is saying that the appendix, which all animals with it got it from a shared ancestor, has evolved regardless of dietary change. They haven't necessarily evolved in the same way, they have just changed and No correlation was found between appearance of an appendix and evolutionary changes in diet, fermentation strategy, coprophagia, social group size, activity pattern, cecal shape, or colonic separation mechanism.
The fact that it has evolved suggests that it is not junk.
That's all the study says. There is no convergent evolution here, sorry.
Do you understand what the study says yet? It didn't evolve separately in different species, they came from a shared ancestor. The study also doesn't say that the changes observed across the species were the same..
Comprende?
As for the wing.. Flightless birds, flying squirrels, etc etc..

You forgot about the flying dinosaurs, didn't you?
Here's a transitional fossil that also has the early stages of wing development two for the price of one for your education, huh?
Transition from reptilian to bird, with wings that were probably used to glide rather than fly.
Species chills in trees, webbed fingers help species survive long falls.. just like with a flying frog. A slightly different shape of hands, maybe a lengthening of a digit or the growth of the hand, helps it further. Add many many many many many small, subtle changes, etc etc
If you don't possess the brain power to see how a limb like that of the mouse could, through millions of years and tiny mutations, could lead to the digits lengthening, the bones slightly changing shape and skin growing between them then.. well..
The same bones and components are all still there.
