Evolutionary Mechanisms: The Theory of Heterozygote Superiority Verses The Selfish Gene Theory
[ send me this paper ]
A 9 page discussion of the mechanisms by which evolution occurs. Contrasts the theory of the selfish gene proposed by Richard Dawkins with that of the theory of heterozygote superiority held to by evolutionary biologists such as E. Sober. An overview of each theory is presented. The conclusion is drawn that although certain “selfish” elements do exist (such as is the case with certain highly repetitive DNA sequences) if these elements replicated to the point where it constituted the entire genome of the organism the organism would be sterile and without offspring the too successful gene would be doomed to death. Bibliography lists 10 sources.

Evolutionary Wonders: Examples from the Plant and Animal Kingdoms
[ send me this paper ]
A 7 page overview of the marvels of evolution as reflected in six very different representatives of the plant and animal kingdom. This paper notes the lessons mankind might learn from birds, insects, and even the lowly parasitic worms as well as food crops such as corn, medicinal plants such as foxglove, and ornamentals such as the exotic water hyacinth.

Examination of Journal Articles on Cells
[ send me this paper ]
A 5 page paper which examines and
analyzes two separate articles dealing with cells. The articles, both originating from
Scientific American, are “A ready-made controversy. (SA Perspectives). (cloning and its
controversies)” and “What clones? Widespread scientific doubts greet word of the first
human embryo clones. (Stem Cells).” No additional sources cited.

Exotic and Invasive Plants
[ send me this paper ]
A 10 page discussion of the attributes of certain plants which give them an advantage over other plants. This paper notes the deleterious impacts on biodiversity which are associated with the arrival of exotics. Bibliography lists 13 sources.

Extinction and Genetic Diversity
[ send me this paper ]
This 5 page paper considers the question of whether extinction is a necessary part of the survival of the species. The question of whether extinction of certain species will inherently reduce genetic diversity has been at the center of recent debates. Bibliography lists 5 sources.

Factors Affecting Stomatal Opening
[ send me this paper ]
This 14 page paper looks at the different factors that influence stomatal opening and how these factors are seen as a biochemical level. The paper outlines the environmental factors that create or inhibit the stomatal opening and then examines the role of guard cells and the way they may open and close the aperture and the way that the actions of the guard cells may be adjusted. The bibliography cites 7 sources.

Faith & Science/Human Need for Religion
[ send me this paper ]
A 10 page research paper/essay that discusses current scientific research into the genetic basis for spiritual belief. The research of Dean H. Hamer is summarized and its implications are discussed. Bibliography lists 7 sources.

Feeding response in crosses between geographical races of the garter snake, Thamnophis elegans: A Critique of the Article by Stevan J. Arnold
[ send me this paper ]
A 5 page review of this article exploring the geographic variance of food preference. Arnold’s article represents one of just a few studies which have explored geographic variation from a behavioral standpoint. Arnold chose to investigate the slug-eating behavior which typifies garter snake populations in mollusk-rich environments, asserting that his study “represents the most thorough documentation of geographic variation in behavior in the vertebrate literature”. Arnold crosses individuals from inland and coastal populations of garter snakes to test the food preference of the first generation offspring. He concludes that there is no perfect intermediacy in regard to the feeding preferences tested. No additional sources are listed.
