Can you identify a single labelled feature in Haeckel's drawings that is not present in the real embryos?
I don't think that's the point - most everybody on the earth has two eyes, one nose and a mouth but if somebody wanted to put across the point that we were all in some way related to some particular person from history like Genghis Khan perhaps, their use of artistic licence could illustrate that point without putting in any new anatomical features at all nor taking them out, just change them to make them all look more similar, it's easy.
That's what Haeckel did, giving a completely false and misleading impression to support his favorite theory.
