Cdesign proponentists claims about Haeckel's drawings in textbooks are greatly exaggerated.

Thanks, a very interesting read...
I particularly find ironic how Wells himself produces his own fraudulent representation of embyological development:
In the figures of embryos (Wells 2000:95, especially stage 4, "gastrulation"), Wells's illustrator resorts to a number of graphic tricks in order to make the embryos appear more different than they are. First, the embryos are not shown from the same rotational angles. The chicken is shown in a different position than the other "Haeckel's first stage" embryos. Second, they are not all scaled the same. In the figure showing the neural crest infolding, the turtle and chicken are shown at a large scale, neglecting the large yolk they sit on, while the human is shown as part of the whole developing ovum, so that the germinal disc and primitive streak formation are shown differently, even though it is shared by all amniotes (Schaunislaund 1903; Nelson 1953; Cruz 1997; Schoenwolf 1997; Figure 9). Also pictured is a frog embryo, despite its indirect development, which is very different from that of the other vertebrates pictured. Many of the general "differences" in early embryo development that Wells mentions are a result of organization due to the yolk size rather than being specific differences in the basic body-plan of the embryo (Arendt and Nübler-Jung, 1999).
