“All new ideas pass through three stages: first they are dismissed as nonsense, then they are rejected as being against religion and finally they are acknowledged as the truth, with the proviso from the initial opponents that they knew it all along.” FirstsIdeasThreeStageOpponentsNonsenseNew IdeasRejectedInitialsAgainst Religion Author:Karl Ernst von Baer
“The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer.
