The Benefits of Genetic Engineering
[ send me this paper ]
(8pp) Have you ever wondered how we as humans have managed to make any progress at all? With any major development there are nay-sayers, or those who know that latest invention will not only derail the future of the world, but also the children of that future. Fear is a major propaganda tool. And we must remember to get the information before we make a decision on any debatable technological advancement: genetic engineering within the area of biotechnology is definitely one of those fields, and provides the basis for this discussion. Bibliography lists 15 sources.

A 9 page discussion of the benefits of bioengineering, the genetic alteration of food species. Presents the contention that genetically altered food species are the key to feeding the world's ever increasing population on the ever decreasing agricultural areas. Counters objections to bioengineering and concludes that it is the people themselves who should decide the direction of bioengineering. Bibliography lists 5 sources.

The Burgess Shale Fauna/Dinosaur to Bird Fossil Record: Parallels and Contrasts
[ send me this paper ]
An 11 page comparison of the simplicity of the animal species preserved in the Burgess Shale Deposit and the complex evolutionary path recorded in the fossil record for modern-day birds. Discusses the controversy and debate surrounding the question of the speculated origin of birds from dinosaurs. Discusses the current findings in the field and the need for additional research. Paper concludes that not only is there no current connection between the Burgess Shale deposit and the evolutionary path of our modern birds, the theories that connect modern day birds to dinosaurs will undoubtedly continue to be challenged in the future. Emphasizes that research is ongoing, however, and that the probability of identifying a clear and irrefutable association between the dinosaurs and the modern birds is more probable than improbable. Bibliography lists 6 sources.

The Ediacaran Biota of the Precambrian: A Separate Kingdom or The Ancestors of Modern Animals
[ send me this paper ]
A 10 page overview of the Ediacaran Biota, an assemblage of fascinating organisms first discovered in the fossil record in 1946. Describes the ongoing controversy as to whether these organisms belonged to the Animal Kingdom or comprised their own previously undescribed kingdom. Presents the ancillary question that if these organisms were indeed animals did they die out in the Precambrian or are they actually the ancestors of modern day animals. Bibliography lists 9 sources.

The Ethics Of Human Cloning
[ send me this paper ]
A 5 page paper. There is an ongoing debate regarding the ethics of cloning. This essay presents both the benefits and dangers of cloning humans. The writer then presents an argument to support one side of the issue. 1 table is included. Bibliography lists 3 sources.

The Evolution of Teeth
[ send me this paper ]
A 10 page outline of the evolution of teeth from the lower vertebrates to more advanced species such as man. Describes the origin of jaw structure and structures such as conodonts (minute toothlike structures) which were the precursors of advanced teeth. Outlines the further evolution of these teeth in the higher mammals with the appearance of features like the hypocone which expanded the grinding surface of teeth and resulted in an explosion of mammal species some forty thousand years ago. Bibliography lists 8 sources.

The Extinction Vortex in Regard to Bees
[ send me this paper ]
This 8 page paper discusses the “extinction vortex” with regard to what it is and how it is used. It also examines such things as the sex ratio, population size and lethal recessive allele with regard to species survival. Finally, it discusses the apparent die-off of bees in the U.S. and considers reasons for it. Bibliography lists 9 sources.

The Future of Human Cloning.
[ send me this paper ]
(7 pp) The idea of human cloning either sounds like something out of a bad science fiction movie, is a boon to medical science or a travesty to morality. As in the case of most exaggerations, there is a shred of truth in all of them. Although our proposed challenge is to project what might happen, some of those projections will be examined under a humorous light. Generally speaking we learn best when we can laugh. Other projections are as assigned. Bibliography lists 6 sources.

The Genetic Pathway and Developmental Evolution
[ send me this paper ]
A 7 page discussion of genetic pathways, specifically the direction of the orderly expression of specific gene subsets, a process which is controlled by tissue-specific transcription factors. Specific DNA target sequences are bound by these transcription factors and, in turn, interact with one another on either a cooperative basis or an antagonistic basis to control expression of the gene subsets. This interaction is aided as well by extracellular signaling molecules which both control and are controlled by the transcription factors. Ties these basic observations together with a review of research on species as diverse as Drosophila melanogaster and zebrafish. An additional 2 pages are appended on this paper which identify several references which could be applicable in an expanded review of this subject. Bibliography lists 13 sources.

The Great Human Diasporas: Implications of the Work of Luigi Luca Cavilli-Sforza for Theories of Cultural Evolution
[ send me this paper ]
A 5 page discussion of the theories presented in the book The Great Human Diasporas : The History of Diversity and Evolution. Recognizes author Cavilli-Sforza as a renown expert in human genetic diversity. Notes Cavilli-Sforza adds significant contributions to the predominant explanations of cultural evolution. His work in linguistics, for example, has been applied to reconstructing ancient routes of human migration. Additional work in genetics complement such observations to allow Cavilli-Sforza to provide considerable insight to the manner in which culture has evolved alongside the biological aspects of human life. No additional sources are listed.
