Think about how baby frogs look like fish, baby insects look like soft-bodied worms, baby horseshoe crabs look like trilobites, baby lampreys look like amphioxus/brachiostoma (primitive cephalochorates), etc. Try a Yahoo on "evolutionary developmental biology."
The controversy is that there's still a lot of evidence for phylogeny in embryology, but there's the club of Haeckel's historical fraud to make it all go away when arguing before the unprepared jurors of society at large and maybe the school boards. Suppressing evidence is the true nature of ID.
I see it as just another Creationist moving goalpost, i.e., prove it's not in every single current textbook and then prove it was never taught that way when it was in a textbook and then prove it not a conspiracy ...
