That's an interesting link (Who Really Opposed Darwin). The article is short and superficial, but the main point is correct. Evolution was, initially, extremely unpopular among
scientists of the time. In fact it may have been the most unpopular scientific theory of all time. And yet, in spite of the strong
scientific prejudice against it, it prevailed among scientists over just a few decades.
It's strange, however, that a creationist would think this fact helps their case.
