True enough.
But it *is* modern Evolutionary theory which has Darwinian theory at its core, including common descent, natural selection and a 4.5 billion year old Earth.
Since Darwinian theory has been augmented and in a sense subsumed by the neo-Darwininan theory, what is the point of attempting to single out and dismiss Darwinian theory? Doing so is roughly equivalent to attacking Newton's work in a discussion of General Relativity.
What was wrong or incomplete with Darwin's concepts have been corrected and expanded upon.
Darwin calls for gradual change over time (evolution).
"Mutation" is nowhere near the definition of evolution: it's
just the opposite.
