I think that typically and consistently you choose to miss or ignore the point Dave.
You erroneously attempt to infer from Gould that an instantaneous appearance of a particular life form can be concluded from the study of geology, despite the vast time spans that geology actually portrays.
To my knowledge Darwin didn't even try specify how gradual, gradual actually must be, "gradual" is a relative, imprecise term.
You however, with your YEC agenda, choose to look down the wrong end of a telescope because actually you don't really want to see how gradual even rapid evolution can be.
Given that a whole environment can change very rapidly indeed or otoh it can remain steady for many thousands/millions of years, as often seen in geology as straight lines, it doesn't surprise me that the life within it responded very rapidly to environmental change or otoh remains largely unchanged if no particular change is called for.
There is no evidence at all that complex life forms can only be explained by a sudden instantaneous appearance, but there is plenty of evidence that life can respond very rapidly indeed when it has to. Any such rapid change would be highly unlikely to be evident from geology and its timescale.
Do you deliberately ignore my references?
I am not quoting from creation sources. What Gould means is clear in his own words. That Darwin believed in uniform and very gradual evolution is not an opinion.
That PE speeds up gradualism and is "bushy", not uniform, not linear, is also historically clear in contrast to Darwinism.
The theory of evolution is always dealing with paradoxes which as religious as it gets.
