The Genetic Pathway and Developmental Evolution
[ send me this essay ]
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 Gray Wolf (Canis lupus)
[ send me this essay ]
A 6 page overview of the behavior, ecology, and management concerns which exist for this fascinating carnivore. The gray wolf (Canis lupus) is not only one of the most impressive of the large North American mammals it is also one of the most misunderstood. Recent conservation efforts have been successful in reviving an almost extinct population but this success has not been without its problems. As wolf populations expand their threat to man, whether perceived or real, grows. This paper emphasizes that proper management of the gray wolf involves not just species specific management but ecosystem management as a whole. Bibliography lists 4 sources.

The Human Digestive System / Its Phylogenetic and Ontogenetic Development
[ send me this essay ]
A 7 page exploration of the concepts of phylogeny and ontongeny in relation to the digesive system. Discusses the embryonic development of the digestive system and points out that, although it is possible that certain phases of our evolution are reflected in our embryonic development, this reflection is sporadic and quite different from the view held in the nineteenth century that an organism's embryological developmental phases give a clear picture of its evolutionary history. Bibliography lists five sources.

The Impacts of Mendelian Genetics
[ send me this essay ]
A 4 page contention that the result of Gregor Mendel's research has not only changed the way people perceive the world, but also the way people live in it. Carefully quantifying his bservations, Mendel was able to come to produce a set of laws that allow us to predict the genetic outcome of specific genetic crosses. Other geneticists have expanded this knowledge and made it an integral component of many aspects of our lives. Bibliography lists 3 sources.

The Importance of Phylogenetic Relationships in Evolutionary Biology
[ send me this essay ]
A 5 page contention that phylogenetic relationships are a critical component of evolutionary biology. Indeed, it is upon our knowledge of phylogeny which we base much of our theory of evolution. Even in “Origin of Species”, that infamous production of an earlier century which many consider synonymous with the concept of evolution, Darwin relies heavily on his knowledge of phylogeny to assess the characteristics of plants and animals which he observed on his scientific voyage on the “Beagle”. Contends that this is only one example, of the many interrelationships of phylogeny and evolutionary theory which have occurred over time. It, along with the somewhat antiquated concept of ontogeny recapitulating phylogeny, however, illustrates the importance of phylogeny to evolutionary theory. Bibliography lists 3 sources.
