It really isn't like any of those Scerp, not even anthropogenic climate change. A theory in science is an entire framework of knowledge and explanation or interpretation of some aspect of the natural world based on a body of scientific facts which are repeatedly confirmed or inferred by experiment and observation with the capability of bringing new discoveries to light. It's one of the pinnacles of human intellectual achievement.
Evolution is the unifying theme for the whole of biology and what Darwin did was two-fold: 1) establishing the fact of evolution with common descent as the pattern of change through various lines of observational evidence and 2) developing a scientific theory - natural selection - to explain the mechanism of adaptation and speciation. It's ubiquitous in life science and was reconciled with Gregor Mendel's work on heredity genetics with the modern synthesis of the 1940s. Any 'debate' over it pretty much ended there.
The real "problem" with Darwin and evolution comes from a sociocultural perspective, because his work further opened the human mind to pursuing scientific inquiry unimpaired by any supernatural prejudices and all but sent the church into full-time retreat, wielding irrevocable impact on the outlook and progression of western civilization on the whole. It was borderline death blow to the good book. He's viewed as an iconoclastic, paradigm-shifting figure of towering historical relevance and often mentioned in the same breath as Isaac Newton for good reason.
Okay, Bro.
