Only when you redefine evolution as a change in a single code unit in a single gene ~ otherwise, using Darwin's title for it "the origin of species", no one has seen it.

Darwin called it the transmutation of species, or descent with modification. Evolution was not his term.

That being said, new species have been observed.

You seem to be suggesting that evolution can be either large-scale or small-scale change, but not both. This is not accurate. Evolution applies to any change in alelle frequency within a population over time.
