Far from being "debunked", The theory of evolution is alive and well. As for Darwin and his theory , it HAS been tweaked and refined as new data is uncovered (as with any new theory or hypothesis)
Support for the theory itself is widespread if not quite universal among scientists:"The vast majority of the scientific community and academia supports evolutionary theory as the only explanation that can fully account for observations in the fields of biology, paleontology, anthropology, and others.[16][17][18][19][20] One 1987 estimate found that "700 scientists ... (out of a total of 480,000 U.S. earth and life scientists) ... give credence to creation-science".[21] An expert in the evolution-creationism controversy, professor and author Brian Alters states that "99.9 percent of scientists accept evolution".[22] A 1991 Gallup poll of Americans found that about 5% of scientists (including those with training outside biology) identified themselves as creationists.[23][24]
Additionally, the scientific community considers intelligent design, a neo-creationist offshoot, to be unscientific,[25] pseudoscience,[26][27] or junk science.[28][29] The U.S. National Academy of Sciences has stated that intelligent design "and other claims of supernatural intervention in the origin of life" are not science because they cannot be tested by experiment, do not generate any predictions, and propose no new hypotheses of their own.[30] In September 2005, 38 Nobel laureates issued a statement saying "Intelligent design is fundamentally unscientific; it cannot be tested as scientific theory because its central conclusion is based on belief in the intervention of a supernatural agent."
