  The Extinction Of Darwinism - Christian-Faith.com
Raup, a senior paleontologist at the University of Chicago, is a leading figure among the scientists who have made "catastrophe" a respectable concept once again in the scientific study of the earth's history.
Raup notes that evolutionary biologists long emphasized competition as a cause of extinctions because the explanation "seemed self-evident," but when they actually tried to test the effect of competition the results were negative.
Raup says that the study of extinctions was long neglected: perhaps the influence of Darwinism kept it off limits.

In 1982, David Raup and John Sepkoski, both of the University of Chicago, examined marine invertebrate biodiversity in the Phanerozoic.
Raup and Sepkoski had boldly suggested the apparent periodicity in the marine extinction record was the result of cyclical astronomical events that vastly increased the probability of the earth being pelted by meteorites.
Raup and Seposki defined an extinction event by the occurrence of an increase in the first stage and a decrease in the second stage.

 Abstract
In the exordium of the speech, Raup acknowledges the existence of these two groups in his audience, but he does so in such a way as to downplay their differences.
  Since Raup refers to his being president of the society in the same sentence, he is using an enthymatic argument (an argument that allows the audience to supply those things that are not said but clearly implied) that presences the minority tribe of paleobiologists without invoking tribal disagreements overtly.
Raup gave this speech shortly after Stephen Gould’s and Niles Eldredge’s “Punctuated Equilibria” article (Spring 1977) appeared and prior to Louis Alvarez’s “Extraterrestrial Cause” article (1980) which announced his discovery of a layer of iridium, a clue that perhaps the earth had been struck by a large meteorite, causing a mass extinction.

Raup displays his commitment to the group's larger project of creating certified knowledge about evolution, but he also reflects his image of the discipline and of his place within it.
Raup opens the paper with two citations, one of G.G. Simpson in 1953 and one of L. Van Valen in 1973, both of which were early attempts of applying techniques from the fields of population dynamics and demography to "patterns of transspecific evolution" (1).

 Reading Notes, November 3   (Site not responding. Last check: 2007-10-19)
Raup is a renown scientist with a great ability to look at nature from fresh perspectives.
Raup is basically laying the mental groundwork for you to break away from the traditional view that life uniformly progresses via natural selection toward more "complex" or "advanced" organisms.
Here Raup takes another view of nature - the abundance of skewed distributions (notice the number of items that are skewed) means that extinction can occur with random changes in populations (Gambler's Ruin).

Established species that are well distributed geographically are extremely difficult to kill off, Raup emphasizes in his studies of extinction; he came to the conclusion that some kind of extraordinary "first strike" was necessary before most of the proposed extinction mechanisms could have a credible chance to work.
Raup and Sepkoski suspected that this mass of data contained some simple patterns that could shed light on the mechanism of mass extinctions, but they had no particular mechanism in mind at that time.
According to David Raup, "The results are mixed: about half support the 26-million-year periodicity (with minor revisions of the period in some cases), and about half find no convincing evidence for cycles of any duration." Raup himself still believes the periodicity is real, but most paleontologists do not.

Shell morphology, according to the mathematical model of David Raup.
Of later studies regarding the theoretical morphology of the coiled shell, the work of David Raup (1962, 1966) is the best-known.
Raup used a computer-based graphical method to produce a range of hypothetical coiled shapes and was then able to see how many of these possible types had in fact been adopted in nature.

 Paleontology at the High Table   (Site not responding. Last check: 2007-10-19)
As part of their reshaping of the field of paleontology, in the late70s and early 80s, Tom Schopf, at the University of Chicago; Dave Raup, Dan Fisher, and Jack Sepkoski, at the University of Rochester; and Steve Gould, at Harvard University, strongly conveyed their excitement and insights into evolution to a new generation of students.
Raup was one of the central figures in the emergence of paleobiology as a discipline during the 1970s.
In 1973, David Raup, Stephen Gould, Thomas Schopf, and Daniel Simberloff—the MBL Group—published the first in a series of research papers describing the results of computer simulations using a stochastic branching model of evolution—the MBL Model—named for the Marine Biological Laboratory in Woods Hole, Massachusetts, where the group convened to begin their collaboration.

Raup is able to draw many interesting theories and conclusions by analyzing extinction as an event and process seperate from and beyond the details of the individual organisms.
Raup analyzes and addresses a variety of potential causes of extinction from biological (such as predation, epidemic disease, etc.) to physical (sea level rises and falls, volcanism, etc.) to fairly exotic (cosmic radiation, asteroid impact, etc.), as well of course interactions between various causes.
What Raup has contributed to extinction debates is the need to look more closely at the correlation between significant geologic [or cosmic] events and species loss.

David Raup (1991) has proposed that PROCESSES other than natural selection are random nasty accidents (field of bullets) and mass extinction (the big kill where more than half of existing species are wiped out in a short time).
This presentation will amplify the arguments set forth by Raup that extinction is a crucial process to undertstand if the fossil record is to be reevaluated.
Raup argues that there is a statistical model that explains the distribution of extinction events across time (across geologic stages).

The paper came from David Raup and John Sepkoski, two respected paleontologists, and they were making the remarkable claim that great catastrophes occur on the Earth every 26 million years, like clockwork.
But David Raup and John Sepkoski had both liked Alvarez's asteroid theory and now were sending their own theory to Alvarez, or rather their findings, as they offered no explanation.
Raup and Sepkoski had collected a vast amount of data on family extinctions in the oceans, far more than had previously been assembled, and their analysis showed that there were intense periods of extinctions every 26 million years.

The nature of extinction is discussed in David Raup's classic short book "Extinction: Bad Genes or Bad Luck?" It can be studied in various statistical ways, for example as a random process.
But some extinction in not random; a great many species go extinct at the same time in what is called a mass extinction, resulting from global environmental catastrophes.
Raup commented in 1991 that much more attention has been given by evolutionary biologists to speciation -- the formation of new species.

It may be of interest too to historians and philosophers of science since the book reflects paleontology's emergence as a quantitative science shaped by recent advances in systematic biology and theoretical ecology.
David Raup, now professor emeritus of geophysical sciences at the University of Chicago, was probably the paleontologist most responsible for paleontology's emergence as a quantitative science; his research covered many aspects of theoretical paleontology from analyzing shell morphology to measuring evolutionary rates.
Raup's and Stanley's text covers all aspects of paleontology from preservation and the fossil record to functional morphology, biostratigraphy, paleoecology, and macroevolution.

 You Can Run, But You Can’t Hide: Mass Extinctions Spare No One
In the largest study of its kind ever performed, University of Chicago paleontologists David Jablonski and David Raup show that mass extinctions wipe out all types of life forms, without regard to special survival strategies they may have developed during times when extinction rates are relatively low.
Smaller organisms require less food, they rebound more quickly from disaster because their populations grow more quickly, and their numbers are larger to begin with (there are more mice than elephants, for example).
But Jablonski and Raup found that for the 350 evolutionary lineages they studied, body size had no relationship to survival rate.
