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 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.
