Thomas Malthus: A great influence in the development of Darwin's theory!

Having done some research I would say that Thomas Malthus had the most influence over Darwin’s development of his theory of natural selection. Malthus famous essay “ An Essay on the Principle of Population” became to be one of the most important bases of Charles Darwin’s thoughts since it gave him support to the discovery of natural selection. His essay affirmed that population growth no matter what “would always overpower food supply growth creating perpetual states of hunger, disease, and struggle. The natural, ever-present struggle for survival caught the attention of Darwin, and he extended Malthus' principle to the evolutionary scheme.” Darwin also noted that "the population-food imblance postulated by Malthus would lead to competition between offspring." http://www.allaboutscience.org/thomas-malthus-faq.htm

Most accordingly the second and fourth bullet points are the essential explanations as the most directly affected by Thoma's Malthus work. The resourses that are needed for an individual to reproduce are limited which will  in fact prevent them from doing so. Confirming once again malthus' beliefs that since population growth would always overpower the food supply then this would cause serious hunger, desease, and cause lots of struggle for certain individuals to survive and reproduce more offspring. Also organisms to better acces to resources will be more likely to survive and reproduce than organism with a lack of them. Therefore if a certain individual reproduces as a rabit does then resources will be scatter and individuals will always be in constant competition to acquire them.

In my opinion I think that Darwin would of been able to develop his theory of natural selection without the help of this certain individual. If Malthus wouldn't had existed I am sure that some one else would of been able to have similar thoughts or Darwin himself by developing his thoughts a little more would of gotten to the same conclusion.

Despite what others though or believed according to religious views Darwin still published his book " The Origin of Species" This didn't stoped him from being able to tell the people through his book how we got here and how natural selection applies to all of us. A different explanation of the existence of species.

  1. Good discussion. I agree with you that Darwin may have been able to draw his conclusions without Malthus. I just think he developed his concepts quicker because of his familiarity with Malthus' arguments.
