Sorry, that happens not to be the case.
"Darwinians" (or evolutionary biologists, paleontologists, and other scientists, to use non-derogatory terms) rely on data and theory, and the scientific method.
There is no need for faith.
[And I have never been able to understand why creationists try to denigrate evolutionary science by saying, "evolution is religion" and "Darwinians actually possess more faith than Creationists." If you want to slam evolutionary theory, you should say its not as good as faith and religion, not that it is the same as faith and religion.]
