the story here is not one of suppression of publication of “The Origin” because Darwin feared the indignation of religious authorities. The story, rather, is one of a natural scientist who wanted to build the best possible case for his theory of evolution of species, who apparently could not stop accumulating additional evidence for his theory, and who eventually was spurred to publication of an “abstract” of his work by the prospect that Wallace would get priority with his publication of a theory of natural selection.
