Darwin's biggest mistake was in his failure to recognize biogeographic
patterns as historically informative. Against that, his gradualism
(which lies at the core of molecular clock systematics) is just a
sideshow.

> Abstract: Although Darwin's many achievements have been justly lauded
> worldwide during 2009, his repeated assertions that all evolutionary
> change
> is imperceptibly gradual have escaped serious criticism from modern
> commentators. The evidence that gradual change results in speciation
is
> circumstantial in even the best documented cases, and usually relies
on
> inadequate assessments of fitness. In contrast, saltational mechanisms
> requiring that radical and instantaneous phenotypic change leads
> directly to
> de facto speciation are still widely ridiculed in most biological
> constituencies, despite accumulating evidence of their viability. This
> lecture aims to redress the balance between gradual and non-gradual
> evolutionary change.
