The 101 mile long Conodoguinet Creek flows through about nine different municipalities‚ so testing for pollution and water quality is extremely important. To figure out the water quality of the creek however‚ we first needed to identify which tests to do. Realizing what the cause of pollution is‚ was our first problem. But‚ using prior knowledge of acid rain and eutrophication in Pennsylvania‚ we found out that those were‚ in fact‚ our main problems/causes of pollution in the Conodoguinet. When figuring

How can the mind arise from the body? Why should anyone be moral? Yet over the millennia‚ there has been an inexorable trend: the deeper we probe these questions‚ and the more we learn about the world in which we live‚ the less reason there is to believe in God. Start with the origin of the world. Today no honest

The Damned Human Race Mark Twain stated that he has been studying the traits and dispositions of animals and contrasting them with that of man. Be he ashamed to report that his findings are humiliating and that the Darwinian theory of the Ascent of Man from the lower animals should be called the Descent of Man from the higher animal. Twain did many “experiments” and spent much time observing his subjects. Twain first talks about how man is ravenous. An English Earl organized a buffalo slaughter

examined the way in which societies adapted to their environment. This approach was more nuanced than White’s theory of "unilinear evolution." Steward on the other hand rejected the 19th-century notion of progress‚ and instead called attention to the Darwinian notion of "adaptation"‚ arguing that all societies had to adapt to their environment in some way. He argued that different adaptations could be studied through the examination of the specific resources a society exploited‚ the technology the society

RadioLab “New Nice” This episode analyzed the domestication of animals. It details an experiment performed by a Russian Darwinian geneticist named Dmitri Belyaev. Belyayev wanted to understand how domestication occurs. It seems like a simple question but the results were very interesting. He used silver foxes for his experiment. He had one control group and one experimental group. With the experimental group he controlled which ones were able to breed. The ones that were able to breed did not show

Abstract Predators are animals that kill for their food; they must do this in order to survive. There has been controversy about predation in some areas including the re-introduction of wolves into the Yellowstone National park area and other areas. Predator-prey relationships are both beneficial and detrimental to some species. The weakest and unhealthiest become dinner for those predators and also become a positive thing for the species that only the strongest of the herd will survive
