What is a chronospecies?
Your biology education is most impressive. Even more so is your ability to educate yourself. Apparently you do not have the initiative to look the term up in any one of the myriad resources you might expect would contain it?

As THOUGH, the cambrian explosion is well documented explained, the most popular explanation at present is that during the previous era the conditions were not suitable for fossilisation, or that if there were fossils they were destroyed.
Bingo. An explanation. I'll touch on this later.

Out of context again, if he really believed what you make him out to believe he clearly would not believe in evolution. He is probably again referring to the Cambrian era.
Incorrect. Here is the rest of the quote.

Each new generation, it seems, produces a few young paleontologists eager to document examples of evolutionary change in their fossils. The changes they have always looked for have, of course, been of the gradual, progressive sort. More often than not, their efforts have gone unrewarded and their fossils, rather than exhibiting the expected pattern, just seem to persist virtually unchanged. This extraordinary conservatism looked, to the paleontologist keen on finding evolutionary change, as if no evolution had occurred. Thus, studies documenting conservative persistence rather than gradual evolutionary change were considered failures, and more often than not, were not even published
I believe this does seem to contradict your statements about the immense amounts of fossil records available as proof for the fact of evolution
BTW, I just read Gould's essay Evolution as Fact and Theory again. It is a ridiculous piece. He relies upon three proofs.
#1.
Quote:
First, we have abundant, direct, observational evidence of evolution in action, from both the field and laboratory. This evidence ranges from countless experiments on change in nearly everything about fruit flies subjected to artificial selection in the laboratory to the famous populations of British moths that became black when industrial soot darkened the trees upon which the moths rest.
I accept that, no reservations. However, it has no validity as a proof of darwinism because Gould is assuming that microevolution implies macroevolution! Since when do rules that govern activity at one level govern activity at all levels? If I want to know how tiny mammals evolved into humans Gould's first proof is irrelevant.

The second argument—that the imperfection of nature reveals evolution—strikes many people as ironic, for they feel that evolution should be most elegantly displayed in the nearly perfect adaptation expressed by some organisms—the camber of a gull's wing, or butterflies that cannot be seen in ground litter because they mimic leaves so precisely. But perfection could be imposed by a wise creator or evolved by natural selection. Perfection covers the tracks of past history. And past history—the evidence of descent—is the mark of evolution.
Evolution lies exposed in the imperfections that record a history of descent. Why should a rat run, a bat fly, a porpoise swim, and I type this essay with structures built of the same bones unless we all inherited them from a common ancestor? An engineer, starting from scratch, could design better limbs in each case. Why should all the large native mammals of Australia be marsupials, unless they descended from a common ancestor isolated on this island continent? Marsupials are not "better," or ideally suited for Australia; many have been wiped out by placental mammals imported by man from other continents. This principle of imperfection extends to all historical sciences. When we recognize the etymology of September, October, November, and December (seventh, eighth, ninth, and tenth), we know that the year once started in March, or that two additional months must have been added to an original calendar of ten months.
Basically Gould is saying here that if all life was created by God and its route was dictated by God, then He would, of course, have made all organisms "perfect." This does nothing to confirm the natural processes by which we evolved from a common ancestor, and it is not a substitute for evidence. Since when do philosophical/theological inquiries constitute proof? The same opinion is held by many biologists, most notably Doug Futuyama and his "tidy-minded engineer."
Gould third "proof" is rather more direct.
Quote:
The third argument is more direct: transitions are often found in the fossil record. Preserved transitions are not common—and should not be, according to our understanding of evolution (see next section) but they are not entirely wanting, as creationists often claim. The lower jaw of reptiles contains several bones, that of mammals only one. The non-mammalian jawbones are reduced, step by step, in mammalian ancestors until they become tiny nubbins located at the back of the jaw. The "hammer" and "anvil" bones of the mammalian ear are descendants of these nubbins. How could such a transition be accomplished? the creationists ask. Surely a bone is either entirely in the jaw or in the ear. Yet paleontologists have discovered two transitional lineages of therapsids (the so-called mammal-like reptiles) with a double jaw joint—one composed of the old quadrate and articular bones (soon to become the hammer and anvil), the other of the squamosal and dentary bones (as in modern mammals).
This is a favorite of Gould, Futuyama, and many others. Therapsida, a large order that contains lots of fossil species that have skeletal features that look like they are intermediate between the features of reptiles and mammals. Reptiles and mammals are very difficult to tell apart at the boundary; normally, if the lowerjaw has several bones, and one of these, the articular, I believe, is joined to the quadrate bone (part of the skull). If the lower jaw is constituted merely by one dentary bone that connects to the squamosal bone (also part of the skull) it is a mammal. Back to Gould, his narrow point is valid, but that does not effectively establish the reptile-mammal relation. There are many more "important" differences, notably, the reproductive system. There are myriads of "transitionals", in fact, there are so many that it is impossible to discern which are the actual ancestors(according to evolutionists). Reference Futuyama. However, lots of candidates is positive only if they can be placed in a single line of descent that could conceivably lead from reptile species to one mammal species. There are many similar fossils that are outside any possible line of descent. One cannot say "mammals in general descended from reptiles in general." That is not Darwinism. Another interesting point is that any chain of therapsids is not attached to something specific at either end (reptiles and mammals). Vital structural differences between early mammals caused some paleontologists to think that mammals had actually evolved several times, that is, that mammals are a "polyphyletic" group. That is kind of messy, considering the Darwinian argument that mammalian homologies are a "leftover" from common ancestry.
So in conclusion, Gould's three "proofs" are looking rather weak. We have an implied equivocation of laws applying to different scales, a philosophical/theological argument that no "tidy-minded engineer" would create an "imperfect" organism, and a specific example of one scenario that does not imply the truth of the more general proposition.
By saying that Darwinism can account for an event or set of events, one is saying nothing. The essence of science is asking the question "how can I prove or disprove my theory?"
