Darwin: Historical Influences

1. Initially, I thought Charles Lyell would be the person I thought most influenced Charlse Darwin to develop his theory of natural selection, but as I read more about each person ont he list, I decided that Alfred Russel Wallace may have the most influence on Darwin. Alfred Russel Wallace was not just a naturalist, he was also a biologist. I definitely think Alfred Russel Wallace was a positive influence to Darwin.


2. According to the book Introduction to Physical Anthropology, Darwin and Wallace reached to the conclusion of natural selection about the same time.  Wallace, along with Darwin, concluded that if the sources are limited there must be competition for food, therefore; it means that the best fit organism will survive. Wallace spent a long period of time in the Amazon to study the factors of evolution. Though he did not reach a conclusion about evolution while in the Amazon, he continued his journey to "the Malay Archipelago." While exploring that region, Wallace managed to collect 125,660 specimens, even discovering thousands of species not known yet to the science world at that time.

3. Wallace believed that population of the species is limited to the resources available, and with limited sources there is always the need for competition for food. There are two bullet point ideas that coincide with Wallace's findings. "Resources are limited. Our planet has a limit of much it can hold and produce. There will not be enough resources available for all organisms to reproduce as many offspring as they can." Not having enough resources mean there are only limited amount of food and water. With limited sources, comes the competition for food, water and living space which goes into the point of who is most fit to survive.  

4. I believe that Darwin could have developed his theory of natural selection without the influence of Wallace, but I absolutely trust that without Wallace, all of Darwin's findings would have taken twice as long as it did with the influence of Wallace. Darwin had other great influences, but Wallace seems to have the closest ideas and findings Darwin had discovered.

5. During Darwin's time, the church was a very powerful political influence. The church affected Darwin's publication of his findings and as a result he feared that his peers will not accept his theories about how life is created. As a result of his doubt, it took Darwin 23 years to publish On the Origins of Species.

Scientific Method...

1.  It is possible that students fall asleep in the rear end of the classroom because they are far from the teacher and other students, therefore; they are not as active in socializing and participation in class

2. To prove or disprove this hypothesis, I will ask a few students in the same class to sit around the subject (who is sitting in the farthest chair from the professor) and purposely raise their hands for discussion and speak with the subject to socialize a bit. Since the people around the subject will be more lively and social, we will see if the student will still fall asleep or not. If the student fell asleep, it would prove my hypothesis to be falsified.

3. An untestable explanation would be students purposely singing the subject a lullaby to make him fall asleep.
