One Out of Five


1. Out of the five individuals I would choose Thomas Malthus as having the most influence over Darwin's development of his theory of Natural Selection.


2. Thomas Malthus was actually an English economist that wrote an essay entitled, "An Essay on the Principle of Population." This essay, surprisingly, had an enormous impact upon the scientific community. It served as an huge influence to Charles Darwin and Russel Wallace in the discovery of Natural Selection. The essay proposed the idea that populations are producing more offspring at a higher rate than the natural resources to sustain them. Malthus' notion of limited resources creates competition among individuals for necessary survival. The scientific community, including Darwin then saw this as an important key to understanding how new species come to be. Some brief links to his influence include:

3. The points directly affected by Thomas Malthus as partially noted above include "What is preventing organisms from reproducing at their potential?" and the fact that resources are limited. These main questions were answered by Darwin in reference to the essay written by Mathus. However, the other subsequent points were then derived from Darwin receiving the answer to these questions. In actuality, Malthus influenced many of these points directly without even having written on the questions themselves.


4. It is possible however, he gives a lot of credit to Malthus' essay for answering his major question of how species came to be. That was because Malthus' proposed the idea of what limits population growth. He also recognized that the facts Malthus derived lead to the struggle for existence which is the key to natural selection.

The Scientific Method and the Irritating Sleepy Student

1. A possible hypothesis would be that the student might not be receiving a substantial amount of sleep to keep him awake throughout the day.


2. This hypothesis can be tested by following the student home to calculate the amount of hours he sleeps overnight. I would then have to follow the student the following day to see the effects of the amount of sleep he received. If the student was lacking in the amount of recommended hours of sleep and falls asleep at some point in his day, whether in class or not, then it would support my hypothesis. However, if the student did receive the recommended amount of sleep and still falls asleep then the evidence would suggest that my hypothesis would be falsified.


3. An untestable explanation that could not classified as a scientific hypothesis would be if the student was getting magically hypnotized by the teacher's voice into a deep sleep after fifteen minutes of hearing it.
