It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection.

The " conflicting theories " have no evidence supporting them and explain nothing.
Charles Darwin's theory of evolution by natural selection was more than acceptable by the evidence then extant and completely acceptable, with modifications, by today's evidence standards. Any non-acceptance is purely ideological.
