They do show signs of waht can be some deformities or just extinct species.
Could "Evolution of Species" have, in reality, been "Extinction of Species"?

I am not discussing that but would not prove what you are saying either.
No they don't show signs of being simply deformed. It all fits, the teeth are the right shape for the jaw, the morphology of the hips supports certain kinds of movement, there is no disease that could account for these, especially since there were more than one example of a species found.
Next, could they just be a branch of apes that went extinct? That also cannot be true, since no modern human fossils are ever found that are contemporary with these. When these hominids existed, there were no modern humans yet.
