There is little doubt that paleontology is going to continue to change, but david Jablonskis Paleontology in the Twenty-first Century serves as a good summary of the present state of paleobiology and how it might change in years to come. The book does go out on a bit of a whimper as Michael Ruses closing essay is a little muddled (Ruse considers the paleobiological revolution as a paradigm gpa shift only to say that it is not productive to think of it in this way but. Readers will no doubt recognize a number of trends that run throughout these sections. Gould, and Thomas Schopf pop up time and again, as do debates about the nature of punctuated equilibrium (both in terms of how revolutionary it was Sepkoskis essay in part ii and where it stands as a theory today whites article in part i, anthony. Encompassing all of this, however, is the transition of paleontology from a discipline incorporated into the modern evolutionary synthesis by simpson to one that produced startling new ideas (i.e. Punctuated equilibrium, species sorting, hierarchical levels of selection,.). Most of the criticisms I have involve individual papers and not the volume itself. I would have liked to have seen some contributions about paleomammology and the incorporation of evo-devo into paleontology (at least partially addressed by jablonskis piece but the editors cannot necessarily be faulted for the absence of such papers. Only so much can fit in a given volume!
Weve said that plan all the time. And Ill never forget george Oster standing up and saying you know, john, we always hear things like this. Well, john, you know. You may have had the bicycle. But you didnt ride. It is difficult to confirm the accuracy of this account, but true or not, it represents the tension between paleontologists and other evolutionary theorists between the 1970s and 1990s. Some theorists may have lamented the lack of communication between the disciplines of paleontology and genetics, but when communication did open up there was sometimes a tendency for the geneticists to say weve known about that for years and decided it was not important. Thankfully the scientists responsible for the paleobiological revolution kept pushing anyway, and modern paleontology is much better for.
Indeed, the german Synthesis is important to understand both in terms of its influence on Anglo-American formulations of paleobiology and as a different sort of evolutionary synthesis. The last section of the book is entitled Reflections on Recent Paleobiology. Where the previous two sections were largely historical and ask the question How did we get here?, the final section seeks to find the place of paleobiology in modern academia and evolutionary theory. The consensus is that the emergence and evolution of paleobiology during the last 40 years marks the transition of paleontology to a more nomothetic or law-producing discipline. Paleontologists are actively contributing to biological and evolutionary questions and not just simply utilizing or incorporating what is being discovered in genetics or molecular biology. This has not always been appreciated by members of other disciplines. Even during the paleobiological revolution some evolutionary theorists did not think anything new or remarkable going. As related in Princehouses essay, this was the feeling of John maynard Smith during a 1980 conference on Macroevolution held in Chicago. Princehouse"s goulds account of a particularly telling moment; maynard Smith got up and made his little announcement, as people always do, oh you guys have presented nothing new here.

Contributions by dinosaur specialist Jack horner and paleoanthropologist Tim White). Among the most outstanding essays in this section is Richard Aldridge and Derek briggs piece on The discovery of Conodont Anatomy and Its Importance for Understanding the early history of Vertebrates. This mostly comes from a personal touch that normally does not often make it into peer-reviewed literature, and to read the anecdotes of contributors to modern parrot paleobiology is refreshing. The second part of the book is called The historical and Conceptual Significance of Recent Paleontology. It is represented by a somewhat more heterogenous mix of papers, containing both historical narratives (i.e.
Susan Turner and david Oldroyds essay on Reg Sprigg and the discovery of the Ediacara fauna) and detailed discussions about methods in paleobiology (i.e. Derek turners discussion of Copes Rule and the running speed. Tyrannosaurus as testable hypotheses). Of particular interest is Manfred laubichler and Karl niklas overview of The morphological Tradition in German Paleontology. As documented elsewhere in the same volume (Patricia princehouses paper on What does It mean to be a darwinian?) the work of German paleontologists like otto Schindewolf and Otto jaekel were important to both the formulation of the modern evolutionary synthesis and later work.
I would argue, however, that the focus on reaching Smiths high table is not very productive. It assumes that paleontology had to (or still must) rise to some level of discourse determined entirely by other disciplines. What is more important is the broader context in which Smith made his statement. The discipline of paleontology underwent a series of major changes throughout the 20th century, and the new volume. The paleobiological revolution, edited by david Sepkoski and Michael Ruse, is essential to understanding why modern paleontology is much more than just the collection and cataloging of dusty old bones.
The difficulty in reviewing any scientific volume created by a platoon of different researchers is that each entry deserves a review in its own right. I cannot adequately do justice to them all. Some entries are excellent, others lackluster, but generally speaking. The paleobiological revolution is an extremely valuable book for anyone interested in the genesis and present standing of modern paleontology. The first major section of the book is titled Major Innovations in Paleobiology. This section sets the stage for the rest of the book, providing the requisite background for the reader to appreciate The Emergence of Paleobiology (outlined in david Sepkoskis excellent review) as well as the state of subdisciplines within paleobiology (i.e.

The report was a critical resume summary of a series of lectures Stephen jay gould had given at Cambridge, and gould considered it the kindest and most supportive critical commentary i have ever received. Smith wrote; The attitude of population geneticists to any palaeontologist rash enough to offer a contribution to evolutionary theory has been to tell him to go away and find another fossil, and not to bother the grownups. In the last ten years, however, this situation has changed by the work of a group of palaeontologists, of whom gould has been a leading figure. The tanner lectures were an entertaining and stimulating occasion. The palaeontologists have too long been missing from the high table. This welcome to the evolutionary high table has had a strong effect on paleontologists. Smiths statement was both complimentary and condescending, and much hand-wringing still goes on over whether the contributions of paleontologists are truly appreciated by geneticists, molecular biologists, and members of disciplines more traditionally thought to be the inheritors of the great Modern evolutionary synthesis of the.
What to do kevin Kirkpatrick, a spokesman for Prevent Child Abuse America, says the Chicago-based groups healthy families America program is a good model for how to reduce child abuse by reaching out to expecting and new parents. The program, which has 330 centers nationwide, offers home visits for parents seeking advice on how to do everything from change a diaper to arrange for immunizations. Begun in paper 1992, the initiative had served more than 200,000 people by 1997, says Kirkpatrick. More important, he says, early evidence suggests that the effort appears to be reducing the incidence of child abuse in participating families.

better training for medical examiners, their staffs, and the people who fill out death certificates so they can be more vigilant about recording cases of deadly child abuse. That way, she says, vital-records offices will be more likely to keep a good accounting of the number of such cases. Getting an accurate handle on the grisly figure is important, herman-Giddens says, because it could help arouse public outrage about the problem of fatal child abuse. That, in turn, could produce bigger budgets for research into the area, and more government and private initiatives to help prevent abuse. If you dont have good data about a problem you cant do much about it, herman-Giddens says. We in the. Have no idea how many children are killed by their caretakers every year.
While child homicides are often well hidden by parents, the biggest problem that encourages underreporting is the system, says Herman-Giddens. Statisticians are forbidden by the International Classification of Diseases from calling a child murder abuse-related without evidence of earlier battery, she says. So, if a death certificate doesnt report a child homicide as abuse at the hands of a parent, the incident gets lost when vital records are tabulated. Take, for example, a case in which a father stabs his infant to death. With no history of abuse, record keepers are forbidden from labeling the incident child abuse, she says. When correcting for the flawed recording, herman-Giddens group found that the national figure of 2,900 abuse-related deaths involving children ages 9 or younger between 19, could in reality best approach 9,500. The incidence of fatal child abuse has been rising in the United States over the last decade, up more than 12 percent a year in North Carolina, the researchers found. Homicide is the leading cause of injury death for babies in this country.

Fatal Abuse Essay, research Paper, the undercounting is due in large part to inaccurate coding of deaths because of strict recording requirements that prevent statisticians at the state level from reporting deadly abuse without a prior history of such violence, experts say. The study is published in this weeks issue of the journal of the American Medical Association. Everyone in the field of child abuse has known this, says writing Marcia herman-Giddens, a child health expert at the University of North Carolina School of Public health in Chapel Hill, and lead author of the study. Its such an unpleasant topic, people just want to avoid. Herman-Giddens, an official at the state medical examiners office at the time of the study, and her colleagues examined 259 cases of child homicide in victims age 11 or younger, between 19Of those deaths, 220, or 85 percent, were attributed to child abuse or battery. The study found that black children were about three times as likely as whites to suffer fatal child abuse. The typical perpetrator was a male parent, and parents of either sex were involved in about 63 percent of child murders, the report found.
