I can find the same structures in all tetrapods. “Wing” is not a morphological feature.
Yes, and we are in the same group as those lobe finned fish, as are other tetrapods.
There is no mammal with a duck beak. Look at the skeletal structure of the platypus and duck, and you will see that they don’t share those features. Also, the common ancestor of mammals and birds laid eggs. Did you forget about reptiles?
Your inability to understand how nested hierarchies work and how homology works is not my failure. It is yours.
