So both Darwin and Gould think that it is small, isolated populations that evolve rapidly into new species. They agree on the mechanism of natural selection, and that species appear quickly in the fossil record. They both agree on the broad timescale of evolution and the fact of common ancestry. They both accept the incomplete nature of the fossil record.
Darwin thought that most evolution happened somewhat gradually within splitting populations, with wide variations in rate, while Gould thought that most evolution happens around speciation, but some doesn't, and that there is plenty of gradualism seen in the higher clade hierarchies, with only speciation being 'punctuated'.
What are you suggesting here? That PE somehow undermines the whole of the neo-Darwinian synthesis?
If you do then you are either dissembling or crazy.
