That is true. But I predict a time will come, and I predict it will be within our lifetime, that Darwinism will be rendered defunct at a theory, primarily because of the siege mentality its proponents have adopted. It is perhaps the only "scientific" theory that does not condone challenges to its orthodoxy.
"I myself am convinced that the theory of evolution, especially the extent to which it's been applied, will be one of the great jokes in the history books in the future. Posterity will marvel that so flimsy and dubious an hypothesis could be accepted with the incredible credulity that it has." -- Malcolm Muggeridge.

If scientists are presented with a better way to explain the mountains of evidence pointing towards evolution they would accept it with open arms. But every new piece of evidence bolsters the Theory.
