The Effect of Infectious Diseases on Humanity - In 1859, Charles Darwin published On the Origin of Species by Means of Natural Selection, a work of literature that not only provided a working framework for the theory of evolution, “descent with modification” by means of natural selection, but also explained how the cumulative impact of natural selection influenced an organism and its environment. Darwin, however, neglected to mention how infectious diseases have served as a pivotal selective force in natural selection (Lederberg, 1999). Since animals first walked the earth, they have had to live with microscopic organism, including bacteria, viruses, fungi, and parasites....   [tags: Medical Research]

Film: Jurassic Park - ... Fortunately, tyrannosaurus remained very close to his biological authenticity, with the only paleobiological errors stemming from a lack in computer animation such as rudimentary ball and joint programs. However, the erroneous nature of the deoxyribonucleic acid or “DNA” and cloning errors are harder to exonerate. The idea of scientists finding complete dinosaur helical chains inside 65 million year old mosquitoes is quite fanciful. Not only would the DNA need to survive, scientists would also need to sort it from the mosquitoes’ own DNA....   [tags: Prehistoric Life, Scientific Innovations]

Somalia - ... It is a parasite; actually it is a worm that lives inside of your blood vessels. This parasite can get into your body through bad water. A freshwater snail leaves the larvae in the water, then people drink it and the larvae get into their body and so on. An additional reason Africa has such poor health is because they suffer from drought and famine. A reason that they have famine is because they the delivery of food is often restricted by fighting among competing tribes/clans.

The beginning of the book tells a story of a place, that was once so beautiful, turned dead and ugly due to a “strange blight that crept over the area” and destroyed everything....   [tags: Silent Spring Rachel Carson Pollution Essays] 714 words

Adaptation - ... After many generations, the population would mostly be composed of individuals with the attractive trait (Wilreker, 7). A third mechanism of adaptation is kin selection (Wilreker, 3). Kin selection is when an individual member of a group acts in a way that helps pass on the genes of one of the individual’s relatives (Wilreker, 8-10). This is because the relative has a percentage of the same genes as the individual, so even if the individual does not pass on its genes, some still get into the next generation because the relative passed on their genes (Wilreker, 8-10)....   [tags: Global Temperature, Environment]
