Hopeful Monster [Link]
> Hopeful Monster is the colloquial term used in evolutionary biology
> to describe an event of instantaneous-speciation,
> saltation, or systemic mutation, which contributes positively
> to the production of new major evolutionary groups.
> The memorable phrase was coined
> by the German born geneticist Richard Goldschmidt (1878-1958),
> who believed that small gradual changes could not bridge a hypothetical divide
> between microevolution and macroevolution.
> In Richard Goldschmidt’s seminal contribution to evolutionary biology,
> The Material Basis of Evolution, he writes:
> “The change from species to species is not a change involving more
> and more additional atomistic changes,
> but a complete change of the primary pattern or reaction system into a new one,
> which afterwards may again produce intraspecific variation
> by micromutation.” (1940, pp. 205-206)
> His thesis however was universally rejected and widely ridiculed
> within the biological community,
> which favored the neo-Darwinian explanations of R.A. Fisher,
> J.B.S. Haldane and Sewall Wright.
