Gould never said that features like eyes or wings evolved all at one; he believed they evolved gradually, just as Darwin thought. The only difference between Punk-Eek and traditional Darwinism is that Gould believed that most species tend to stay stable for long periods of time, and then evolve in a relatively quick (in geologic terms-- still tens of thousands of years) period in response to environmental changes.
In other words, Gould was a traditional Darwinist who came up with Punk-Eek to explain why the fossil record contained no evidence of traditional Darwinism.
"The thing that evolutionists seem to have overlooked about the 'missing link' is that it is missing." -- G.K. Chesterton
That's putting it kindly. Difference between Gould and Darwin was that Darwin thought that fossils could prove evolution true, Gould knew they did not and never would but wanted to stay on the evo gravy train nevertheless. Punk-eek is totally unverifiable and unfalsifiable.
