Back to Haeckel: Creationists use Haeckel as a scapegoat to discredit the entire field of developmental biology, and its use by evolutionary biologists. This would have been absurd enough 100 years after his death, when developmental biology hadn’t really progressed all that much, but it’s particularly absurd today when the discipline has merged with molecular biology and genomics to form “evo-devo”, and all of the morphological evidence is being supported and extended by information at the molecular level. I can’t tell you the number of times that I’ve tried to give creationists some information from this area of science, only to be told that I’m simply out of date because I apparently don’t realize that Haeckel was disproved.
