No, I don't see that as possible. The science of embryology had discredit it completely by 1925. Yet I just did a little web searching and discovered it is still included in many high school level textbooks. It was universally taught until at least the 90's.
Do you really think it was just a little 70 year long oversight?
Plus, there was a admission, I wish I could could remember by who, that it had continued to be taught because, "it was a good evolutionary teaching tool".
Also, there are numerous other such examples. I'm going to call it a night, but I'll list several other very similar situations tomorrow.
