A fundamenal change in the Protestant objections to evolution occurred after about 1875. Previously, citing Louis Agassiz and other scientific luminaries, Protestant contributors to religious quarterlies dismissed Darwin's theories as unscientific. After 1875, it became clear that the majority of naturalists were in favor of evolution, and a sizable minority of these Protestant contributors rejected Darwin's theory because it called into question the veracity of Scriptures. Even so, virtually none of these dissenters insisted on a young Earth.
