Abstract
This paper explains that the fossil records tell us that, through out the geological history of earth, mass extinctions have been the norm rather than the exception. This paper states that a better understanding of the role extinction plays in evolution is essential. The author concludes that human beings are uniquely adaptable; they invent procedures as medicine that give them extended control over their environments.
From the Paper
"Of course, the most famous extinction event is that of the dinosaurs, about 65 million years ago. Such events appear in the fossil record as far back as Precambrian time when it is believed that life first began. Ideas of mass extinction has been an issue of controversy between many geologists towards the idea that it is related to intermittent catastrophes such as the striking of the earth's surface by a large asteroid or comet. Many paleontologists and evolutionary theorists reject such ideas and believe them to be unjustified."

Abstract
This paper takes a look at the Permian and Cretaceous-Tertiary periods of life on Earth - pre-historic forms of life from sea creatures to land and air creatures. During both of these periods, mass extinction occurred and a comparison of these two extinctions is documented in this paper.
From the paper:
"From the perspective of daily human life, we often think of tragedy on the level of individual death and destruction, and the concept of mass extinction as being confined to a species or at worst, an ecosystem. However, over the course of the existence of the earth, the planet has weathered many greater catastrophes. Geologists must take a much longer-term perspective of catastrophe when studying extinction. This paper will compare and contrast the Permian and Cretaceous-Tertiary mass extinctions."

Abstract
The extinction-level event that occurred during the Permian period, often known as the Great Dying, forms the boundary between the Permian and Triassic geologic periods. During this time approximately 95 per cent of all marine species died out. This paper presents an overview of this time period and the explanatory theories regarding this event.

Explanatory Theories Regarding the Permian Extinction
Conclusion
From the Paper
"It has been suggested that this increase in carbon-12 could be the result of upwelling of frozen methane hydrate from the ocean floor. Experiments have shown that a sea temperature rise of 5?C would be sufficient enough to gasify solid methane hydrate. This would lead to huge amounts of greenhouse gases being expelled into the atmosphere, and could have led to the mass extinction ("Permian-Triassic")."

Abstract
This paper will consider the relation between the British Columbia public transit service's new "Stop Request" program, in relation to the transportation needs of Vancouver's Downtown East Side residents. This paper will examine these issues with Beauregard's (1989) modernist/postmodernist perspective; and the usefulness of Young's (YEAR) discussion of the five faces of oppression, as a way to more specifically characterize the people of East Side Vancouver in relation to their marginal location in the city and in the society and their relation with issues of "safety".

Evolutionary Psychology, 2006.
A discussion of evolutionary psychology as the bridge between social science and Christianity.

Abstract
This paper discusses evolutionary psychology, a multi-disciplinary approach to science and philosophy intended to reveal why and how human beings seek out a higher power. This paper discusses how the relatively new field can be used to help interpret the affect of family life on personality as well as the evolution of humanity and our development into social hierarchies. In other words, the paper explains, evolutionary psychology maintains that man should no longer be considered to be a creature of his cultural development -- but instead, cultural developments should be considered to the outcome of man's evolutionary needs and deeds. By critiquing evolutionary psychology, the paper also confronts questions such as: What is at stake in the contemporary drift back to the child-rearing patterns of our mammalian cousins where females provide the care and socialization? and Why do we as a species gravitate towards religion? The paper concludes that evolutionary psychology may ultimately reduce the ideas of the social scientists and elevate those with religious fervor. Therefore, the paper agrees that evolutionary psychology is a bridge between the social sciences and Christianity -- but in a negative sense.

Conclusion
From the Paper
"Discourses on specific relationships between societies, religious factions and their natural environments have been a persistent feature of human nature. There have been numerous writers, philosophers and thinkers that have routinely attempted to tie science, social science and religion together in some elaborate social theory. "The discussion of disciplinary history sheds light on what have often been long and intricate conflicts over the demarcation of disciplinary boundaries, in particular between the biological and social sciences. Any attempt to cross the boundary between biology and the social sciences makes visible the connections and reveals the blind spots created by these disciplinary divisions. Past history is still present in the definition of concepts, the images created by them, and, above all, in the resistance to interdisciplinary interactions. For these reasons, awareness of the sources of potential misunderstandings can help focus attention on real, rather than spurious, disagreements." (Maasen, Mitchell, Richerson, & Weingart, 1997)"

Abstract
In this article, the writer notes that the reasons behind risk taking behavior have baffled psychologists and sociologists for many years. This research explores new theories that might help to explain why people love to take risks. It revisits some of the older theories and adds insight into emerging philosophies on risk taking behavior. The proposed study takes into account current theories on risk taking behaviors, but focuses on Griffiths' psycho-evolutionary theory and its impact on risk taking theory. The writer examines several new theories including biophilia, intra-indigenous consciousness, theories in adventure education, and social disconnectedness. The paper also includes appendices, showing details of survey and an IQ test.

From the Paper
"People can be divided into risk takers, risk reducers and risk avoiders. This is termed as the person's risk orientation. Risk avoiders tend to avoid situations that they feel are risky. Risk reducers partake in an activity, but ignore, or refuse to acknowledge the risks involved. Risk takers appear to be attracted to the risks themselves and will participate in an activity because of the risks involved. It is this third category, risk takers that this research will be most concerned with. The purpose of this research will be to tie traditional theories about risk taking to the psychoevolutionary theory in order to examine the possibility of an evolutionary basis for the propensity towards engaging in risky behaviors."

Abstract
This paper examines, through collected evidence, whether or not altruism can occur under the premise of evolutionary biology. It explains what evolutionary biology is and then explains the concept of altruism. It then goes on to explain why altruism is a paradox for evolutionary biology. The paper presents theories on altruism in an attempt to explain and minimize this paradox.

From the Paper
"There are many different results that are possible within this experiment. First, the expected result is that the majority of individuals will answer that they would act altruistically. However, they could act altruistically in some cases, as when they are giving change back to others, but selfishly when it comes to saving a drowning person and risking their own lives. Another scenario is that they could act selfishly when they are in the room by themselves, but when they are doing so in conjunction with someone else, they might be motivated by the visual sign of someone else to be altruistic. I argue that in most cases individuals will be altruistic and that they are altruistic because it is a reciprocated trait. When it comes to the questions of whether they would act altruistically knowing that the other person would not do the same. I believe the majority of individuals will still act altruistically. Although this result might differ from person to person."

Abstract
This paper looks at the idea that evolutionism is tied to an idea of primitive society that crystallized in the 1860?s and 1870?s. It discusses Darwin?s Origin of the Species which appeared in 1859 and how over the next two decades a plethora of books appeared about primitive society. It analyses how these books assumed a unilineal progression from ?primitive? society to modern society and how although these thinkers were called evolutionary, their thinking bore little resemblance to Darwinian evolutionist theory. It explores the thought of evolutionary anthropologists and attempts to discover the methodological and theoretic problems with their arguments. It also examines how evolutionary ideas are transmitted, in an attempt to discover the secret of the longevity.
From the Paper
"One can note that way evolutionist schemata?s are constructed as a gradual progression away from ?nature? as constituted by the west. For instance, all primitive societies are based on kin, and in Morgan?s scheme, it is only after the creation of the monogamous society that private property becomes a possibility. The postulation of an original type by evolutionist theorists is problematic now because such ideas are seen as mere speculation. Furthermore, we are aware that there is a heterogeneous mix of each group that the theorists took to be original types. One methodological criticism underlying all the theorists we will look at is that they took modern hunter-gatherer societies to be representative of prehistory, even though we are now aware they are dynamic societies shaped and changed by their contact with colonialism and agricultural society."

Abstract
This paper ananlyzes the hypotheses presented in Robert Boyd and Peter Richerson's seminal work "Culture and the Evolutionary Process." The reviewer considers assumptions presented in the book which underline the relationship between science and culture in promoting human evolution. The paper also shows links between Boyd and Richardson and earlier research in the field. The reviewer concludes that the discussions and analyses in "Culture and the Evolutionary Process" uncovers explanations and generates further understanding of how humans and human society came about, and continues to develop in the present.
From the Paper
"Boyd and Richerson provide two general assumptions that lead to their hypothesis, which posits that science and culture significantly influence each other in understanding the human evolutionary process. In the words of the authors, "process-oriented "scientific" analyses help us understand how history works, and "historical" data are essential to test scientific hypotheses about how populations and societies change" "

Abstract
This paper discusses the study of human sexual behavior and human sex differences, which has been approached from many different points and in recent years has been viewed through the lens of evolutionary theory. Evolution tries to explain human bodies, and also human minds and behaviors, and it explains not only vague human potentials and capacities but also things far more specific about ourselves than we had thought possible. However, despite agreement on the evolutionary theories, many writers could not accurately explain the idea of human mating choices. Earlier theorists and writers have adhered to the earlier concepts of mating and choices of men and women while changes developed in their roles. For example, women became more open in their relationships with men instead of being a subdued partner. This paper discusses the way these changes have been seen in the current roles of women.

Conclusions
From the Paper
"The perception is that males assign so much importance to attractiveness that when constrained they ignore personal attributes that appear to be critical for the viability of a long-term romantic relationship. A major drawback of explanations based on social theories is that they do not specify why people in diverse societies assign great importance to attractiveness in the first place. Because attractiveness signals attributes that are crucial for reproductive success, attractive people are pursued by many as potential mates, inculcating and reinforcing their beliefs about their greater desirability compared to unattractive people. The possession of highly sought-after traits would allow attractive people to be choosy, demanding, and less compromising in relationships. Attractive women were perceived to be vain, dishonest, less moral, to have a lack of concern for others, and to be more sexually provocative than less-attractive females. Such a cluster of negative attributes or the other side of the attractiveness stereotype is difficult to explain on the basis of social theories of stereotype formation. An alternative explanation would be that attractive females do, at least occasionally, engage in behaviors that are not held in high regard, thereby giving the 'darker side of beauty' some basis in truth (Alley & Hildebrandt, 1988). The stereotypical belief that attractive women are not very faithful, although consistent with the findings of the darker side of attractiveness, creates a puzzle as attractive women are also rated as most desirable for a long-term relationship. This shows that the female must offer some other qualities as well."

The Early Evolutionary History of Horses, 2002.
This paper is a cladogenetic view of the early evolutionary history of horses.
2,365 words (approx. 9.5 pages), 8 sources, APA, $ 72.95

Click here to show/hide summary
Abstract
This paper discusses that, for many years, paleontologists held that the evolution of horses, as evident in the fossil record, was anagenetic, or progressing in a virtually straight, single line of evolution; but more recently paleontologists have found evidence supporting a cladogenetic evolutionary pattern in the Miocene, which created a multiplicity of horse species or "branches" on the evolutionary trunk. The author points out that, as the fossil record yields more and more of its "secrets" to paleontologists through new investigative technologies, the established theories require revision.

Summary and Conclusions
From the Paper
"The fossil record of horses (family Equidae) over the past 55 million years is a classic example of macroevolution. North America is the ancestral home of horses and many fossil sites across the continent have been identified as containing abundant remains of ancient members of the family. ... states that any given fossil locality in North America from about 50-55 to 20-25 million years ago, it is usually possible to find 2-4 species of horses that seem to have lived side-by-side. However, from about 20-10 million years ago, the fossil record suggests that horses evolved rapidly, adapting to various environments and ways of life."

Darwinian Anthropology and Evolutionary Psychology, 2002.
This paper compares and contrasts the two major views of the cultural development of humans: Darwinian Anthropology and Evolutionary Psychology.

»
Click here to show/hide summary
Abstract
The writer explores the similarity between the two theories in that each acknowledges the evolutionary mechanisms for behavior that have been inherited. The rest of the paper highlights the ways in which the theories diverge: Darwinian Anthropology feels these are secondary to modern cultural influence while Evolutionary Psychology feels they are primary in explaining how and why we behave as we do.
From the Paper
"Many feel that a combination of the two theories is a viable solution to the differences and weaknesses we have found. While this is not a direct comparison of our two original theories, it is important to look at ways in which they could coexist. These coevolutionary theories combine the study of current adaptations in current culture to help understand the evolution of mechanisms which initially drive the culture. The inverse is also true; studying the mechanisms of evolution in the human mind helps to understand why we behave as we do in modern society."

Abstract
This paper discusses two major views of the cultural development of humans, which are Darwinian Anthropology and Evolutionary Psychology. This paper examines both theories and finds that they have similarities, the most obvious of which being the basis of said development on the evolutionary theory of Charles Darwin. Each has its own justifiable points on human development; likewise each has its fallacies. It is the intent of this paper to explore these similarities and differences as well as the ramifications thereof.
