Before we come to the sort of sudden bursts that they [Eldredge and Gould] had in mind, there are some conceivable meanings of `sudden bursts' that they most definitely did not have in mind.These must be cleared out of the way because they have been the subject of serious misunderstandings.This is a collection of quotations from Don Patton on the subject of evolution.
My point here is that, when we are talking about gaps of this magnitude, there is no difference whatever in the interpretations of `punctuationists' and `gradualists'.I endeavoured, also, to show that intermediate varieties, from existing in lesser numbers than the forms which they connect, will generally be beaten out and exterminated during the course of further modification and improvement.The main cause, however, of innumerable intermediate links not now occurring everywhere throughout nature depends on the very process of natural selection, through which new varieties continually take the places of and exterminate their parent-forms.Centered headers, below, are his categories; the rest are mine. Changes in atmospheric partial pressures of carbon dioxide produce corresponding changes in carbon dioxide solubility. Sloss, [T]his quote only demonstrates that, sometimes, under the right conditions, limestones can form by inorganic processes.Because of these relations, there is a direct connection between atmospheric carbon dioxide and the amount of dissolved calcium ion in sea water. One look at the rest of any texbook on sedimentology, and you will realize that most limestonare not inorganic anyway.
These contingencies will concur only rarely, and after enormously long intervals.
