Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg Oct 1986

Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eulimdana rauschorum n. sp. is described from southern black-backed gulls, Larus dominicanus Lichtenstein in Antarctica. The species is most similar to Eulimdana lari (Yamaguti, 1935) from Charadriiformes in the Holarctic. Males have spicules equal in length that are asymmetric in structure distally. There are 4-5 and 3-5 caudal papillae in rows to the right and left of the anus, and two small genital papillae at the posterolateral margin of the anus. Females have a variable number of prominent caudal papillae and large microfilariae (365 μm in length). The morphological similarities and host distribution of E. rauschorum and E. lari suggest …


Evolution And Historical Biogeography Of A Parasite-Host Assemblage: Alcataenia Spp. (Cyclophyllidea: Dilepididae) In Alcidae (Charadriiformes), Eric P. Hoberg Jan 1986

Evolution And Historical Biogeography Of A Parasite-Host Assemblage: Alcataenia Spp. (Cyclophyllidea: Dilepididae) In Alcidae (Charadriiformes), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The methodology of phylogenetic systematics was used to develop hypotheses for the evolution of eight species of Alcataenia, a group of host-specific cestodes of the Alcidae and, to a lesser extent, the Laridae (Charadriiformes). Concurrently, aspects of the early biogeography of alcids were reevaluated making it possible to study the historical and distributional relationships of parasites and hosts. The most parsimonious hypothesis for the phylogeny of Alcataenia suggested that sequential colonization or host switching with limited coevolution (coaccommodation) by parasites best explained the distributional patterns exhibited by Alcataenia spp. Morphological evolution of specific species of Alcataenia accompanied host switching, …


A Molecular Phylogeny Of The Grunts (Perciformes: Haemulidae) Inferred From Nuclear Rag1 Gene Sequences, Millicent D. Sanciangco Apr 1984

A Molecular Phylogeny Of The Grunts (Perciformes: Haemulidae) Inferred From Nuclear Rag1 Gene Sequences, Millicent D. Sanciangco

Biological Sciences Theses & Dissertations

Species and genera of Haemulidae have undergone various taxonomic revisions, however, there is no study that infers the phylogeny of the haemulid genera using morphological or molecular data. The purpose of this study was to use approximately 1386 base pairs of the nuclear Recombination Activation Gene-I (RAG1) from 35 haemulid species representing 13 genera, one species of the closely related Inermiidae, and two species of the outgroup Sparidae to infer an intrafamilial phylogeny of Haemulidae. This analysis is corroborated using approximately 650 base pairs of the mitochondrial Cytochrome Oxidase I (COI) gene and RAG I-COI combined gene analyses of27 haemulids, …


Areographic Representation Of Faunal Characteristics Through A "Second Order" Relational Approach, Charles H. Smith Aug 1983

Areographic Representation Of Faunal Characteristics Through A "Second Order" Relational Approach, Charles H. Smith

DLPS Faculty Publications

Areographic analysis has traditionally depended on primary data consisting of location-specific tallies of presence or absence of given forms. In the present work, an alternate manner of representing distributions is suggested. Regional units are first established, and presence and absence of the forms under consideration in these units is noted. The relation of the biota at any given point location to all others is then established through examination of the former's characteristics of inclusion in the latter. This is accomplished by detailing regional level trends of inclusion and setting up a "second-order" distribution of associations. Two kinds of descriptive information …

In this paper certain crucial differences between the evolutionary theories of Charles Darwin and Herbert Spencer are explored. Particular attention is given to the Lamarckian basis of Spencer's evolutionary doctrine.


Some Interactions In The Evolution Of Man And Tools, Gary W. Weston Aug 1971

Some Interactions In The Evolution Of Man And Tools, Gary W. Weston

All Master's Theses

This paper looks at some of the interactions between the development of tools and the evolution of man and his ancestors. It begins with a brief history of life up to the primates as a foundation. Next the use of tools by other animals is examined followed by the coverage of the period of time from Australopithecus to Modern Man showing the interweaving of physical and mental evolution of man and the development and refinement in his physical tools. Lastly, a look at possible future interactions in the physical and mental evolutionary developments in man as influenced by his tools …


Evaporative Water Loss In Two Northwest Snakes: Pituophis Catenifer And Crotalus Viridis, Donald R. Woolery Jun 1971

Evaporative Water Loss In Two Northwest Snakes: Pituophis Catenifer And Crotalus Viridis, Donald R. Woolery

All Master's Theses

A study by Gans, Krakauer and Paganelli (1968) dealt with twenty-six species of snakes representing five families. They found that the "rate of water loss was proportional to surface area" and that water loss correlates with the aridity of the selected habitat. No comparative information resulting from the direct separation of the pulmonary and cutaneous avenues of water loss is currently available. Also, no direct comparisons of this separation in sympatric species are available. These comparisons are the basis for this study.

4. Social Darwinism, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

The singular impact of Darwin in fields other than biology can be attributed largely to one man, Herbert Spencer (1820- 1903). It was Spencer, not Darwin, who coined the expression "survival of the fittest." Although neglected today except by historians of the nineteenth century thought, Spencer's influence on his own time was so great that Justice Oliver Wendell Holmes was able to wonder if "any writer of English except Darwin has done so much to affect our whole way of thinking about the universe." Herbert Spencer was born into a traditionally nonconformist English family of modest means. He refused a …

2. The Impact Of Darwinism On Religion, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

The tremendous impact of evolution upon Western religious thought resulted in large part from the sweeping implications of the theory itself, which challenged the basic tenets of traditional dogma. It is difficult to understand the nature and intensity of the controversy that developed, however, if it is not understood that the challenge was given additional weight by the ascendency of science in the nineteenth century. In considering the influence of Darwin's findings on religion, as on other areas of thought, it should be kept in mind that the theory of evolution was presented to a world that was observing a …

1. Charles Darwin And Organic Evolution, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

Evolution was not a new idea. The Greeks speculated on it. In the century before Darwin many different evolutionary theories were proposed, among them notable efforts by Buffon, Lamarck, and Goethe. Their common thread was the concept that the succession of biological changes in geological time represented a fact, if not a natural law. The stumbling block was for all of them, as it had been for Cuvier, the concept of fixed species, which clashed with the vision of a distant past populated with races of plants and animals now extinct. It became evident that the idea of fixed species …

3. Darwinism And The Rise Of Social Science, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

The two areas of the social sciences which were more stimulated by Darwin's research were anthropology and sociology. The Frenchman, Auguste Comte (1798-1857), generally regarded as the father of sociology and the originator of that term, laid the groundwork for the immediate application of the law of evolution to the study of society. Comte's conception of sociology is derived from his philosophy of history. Sharing the Enlightenment belief in progress, Comte saw history evolving through three stages. The first was the theological stage, in which men supplied supernatural explanations for the natural and social phenomena. This was followed bu what …

5. Social Darwinism Reconsidered, Robert L. Bloom, Basil L. Crapster, Harold L. Dunkelberger, Charles H. Glatfelter, Richard T. Mara, Norman E. Richardson, W. Richard Schubart

Section XV: Biology and the Rise of the Social Sciences

Although the contemporary reaction to the implications of evolution was generally one of long-term optimism, an antithetical reaction did exist. Seen in stark terms, evolutionary theories were depressing to those who, on religious or humanitarian grounds, found the reduction of life to an irrational and brutal struggle for existence disturbing and provocative. There was, however, an important body of thought which accepted Darwin's findings without embracing the social or ethical implications of Social Darwinism. Many who studied Darwin came to the conclusion that it was possible to concede that man is an animal, but an animal capable of moral and …


A Comparative Study In The Field Of Genetics Of The Organic Evolutionary Hypothesis And The Scriptural Account, A. Delbert Rice May 1955

A Comparative Study In The Field Of Genetics Of The Organic Evolutionary Hypothesis And The Scriptural Account, A. Delbert Rice

Western Evangelical Seminary Theses

Since the beginning of the Church Age, the field of Biblical Apologetics has been the battleground for many acrimonious words and hasty conclusions and the scene of many misunderstandings. Since the advent of the popular exposition of the organic evolutionary hypothesis with Charles Darwin in 1859, many things, based upon a false understanding of the Scriptures or upon a false understanding of scientific evidence, have been said and many accusations made on both sides of the argument. This study has been undertaken to sort from the tons of discussion which have been put forth the few pounds which can be …

How Far Is The Argument Of Homology Acceptable To Reason, Wilmur Daniel Ackerman Jul 1931

How Far Is The Argument Of Homology Acceptable To Reason, Wilmur Daniel Ackerman

Bachelors’ Theses

Evolution is a subject that involves a great deal more than the average person really thinks about. To approach subject like this, one must try to obtain as many of the different factors that taken into consideration as is possible.


The Theory Of Spontaneous Generation, Arthur Thomas Kuesel Jun 1924

The Theory Of Spontaneous Generation, Arthur Thomas Kuesel

Bachelors’ Theses

The theories concerning the origin of life on this planet have been many and varied all down the ages. In the prescientific ages, if we may be allowed to designate those years as such, before science was as exacting and searching sit is now, practically all the theories advanced by the philosophers at the time have since been proven to be fallacies and all of them save one, the Theory of Spontaneous Generation have been discarded into the limbo of mistaken notions.

Embryology And Evolution, Malo Marius Amunson Jun 1906

Embryology And Evolution, Malo Marius Amunson

Manuscript Thesis Collection

The proofs of evolution must be sought in the entire field of science. Direct proof is found in the study of Morphology, whose bases are comparative anatomy; embryology; in the study of paleontology, of geology, of geographical distribution, in the study of nature and experiments of today. In this vast field of direct proofs of evolution it is our purpose to present some of the evidences of evolution as furnished by one of these, namely, Comparative Embryology.


Evolution And Classification, Charles E. Bessey Sep 1893

Evolution And Classification, Charles E. Bessey

Papers in Systematics and Biological Diversity

As we have gathered up the scattered masses of botanical knowledge, laboriously wrought out by many isolated workers, and attempted to fit them together into a consistent whole, which should outline the structure of the temple of botany, we have found that the workmen have not always followed the same architectural plan, and have often used different units of measurement. With the increasing specialization so noticeable year by year there is a corresponding lack of coordination of work. To this lack of coordination, this want of unity of measurement, this misunderstanding of plan, we can no longer close our eyes, …
