Haeckel falsified his embryo pictures

Claim

Ernst Haeckel faked his pictures of embryos to make them look more alike than they are.

The self-correcting nature of science allows for inaccuracies like that of Haeckel to be exposed and rejected if they are found.
Haeckel did not fabricate any details in his embryo drawings; rather, he emphasized the details he was interested in and de-emphasized others. In effect, he drew a sort of caricature, and the distortion which resulted from Haeckel's emphasis and de-emphasis was comparatively small. That even this relatively minor departure from strictly objective accuracy caused Haeckel's embryo drawings to be rejected by the scientific community, may be taken as a measure of how greatly scientists prize objectivity.
Regardless of any claim about tampering with the visuals of embryos over a century ago when Haeckel was working....there is abundant evidence from modern visualization techniques that Haeckel's noting of embryonic similarity (though his explanation for why there should be similarity in the first place has long been disproved) across species is in fact empirically true. Moreover, an abundance of developmental and genetic studies have demonstrated unequivocally that the homology goes even deeper, all the way down to significant similarities in fabricational genes across what distantly related species. Why the fuss?
