Theories of Evolution and Natural Selection - Essay Example

I would like to bring into play this opportunity to unveil my observations.
When I analyzed the features of the species what I understood is that animals with variations can adapt to the environments they live in. They have a better chance of survival and the ability to breed. They hand over their characteristics to their children. I know that it has paved the way for controversies, especially as it diffuses the literal interpretation of the Book of Genesis in the Bible. I have also noted that “Populations remain roughly the same size, with modest fluctuations” and “Food resources are limited, but are relatively constant most of the time” (Charles Darwin: The theory of evolution, 2010). It has led me to the inference that surviving in such an environment is a struggle among individuals. “In the struggle for survival, the fittest win out at the expense of their rivals because they succeed in adapting themselves best to their environment” (Charles Darwin: The theory of evolution, 2010). Let me invite your kind attention to the American novelist Jack London’s widely read novel, The call of the Wild. The novelist presents the character of Buck as an animal that is adapted to the environment it lives in. Here the dog, Buck learns fast to be a sled dog and pack leader.

I am sure that any researcher or student of science must have brooded over the very existence of organisms, the scarcity of resources, and the subsequent survival of various organisms and so was I. My observation of the various organisms convinced me that there is a clear-cut link between the existence of various species and the scarcity of resources; this association between the two was instrumental in the formulation of my theory of evolution by natural selection. Later, I realized that “organisms with favorable variations survive and reproduce at a higher rate” and that it is the organism’s ability for adaptation that “increases an organism's chance of survival in a particular environment” (Evolution by Natural Selection). This realization prompted me to coin the term natural selection to emphasize that evolution by natural selection would occur when this sort of adaptation spreads to all the organisms on this earth. I am really happy to share my observations, my experiments, and the way I formulated my theories in front of such a studious audience as you. I wish and pray that this short speech will inspire your aspirations, goals, and ambitions to seek and find the unexplored mysteries of the universe. With this, I conclude my speech. Thank you.
