Throughout my education, once I decided my ultimate interest is in Anthropology, the term natural selection is a something that I’ve been familiar with for some time. Natural selection is the process where organisms learn to adapt to their environment in which they fight to survive and reproduce. Charles Darwin’s first exposed his idea on natural selection in On the Origin of Species by Means of Natural Selection. In this paper I will discuss what elements have to be in place for natural selection to operate and how it exactly works. Then I will compare and contrast natural selection with Lamarck’s inheritance of acquired characteristics theory. First, one would need to understand the basis on which Darwin based his theory on for natural selection to occur. Natural …show more content…
All of these elements then produce a trait, either genetically (genotype) or physically (phenotype) of a species. From generation to generation, the fight to survive, or what Darwin called the “struggle for existence,” will favor one species over another causing a change in the density of certain traits in a population. Therefore, in order for natural selection to operate, a trait must be heritable and that trait must have its’ advantage in the fight for the resources needed to survive. If any of the four important elements do not occur, then a trait cannot bring forth the theory of natural selection. To explain how natural selection works, imagine a population of beetles that vary in color, some are green and some are brown. Seeing that the environment cannot fully

Jean Baptiste Lamarck's Theory Of Natural Selection

Jean Baptiste Lamarck born on August 1, 1744, was a naturalist that considered himself a natural philosopher and a physicist that looked down on the synthesis that was the Enlightenment. He started out as an essentialist where he had believed species were unchanging, but after work on the Paris Basin on Molluscs, he found that transmutation in the nature of organisms occurred over time. Lamarck was then convinced in that changes in the environment had impacts on organisms that would change their…

world. Lamarckism is a theory created by Jean-Baptiste Lamarck between 1809 - 1815 it is the theory of inheritance. Inheritance is the theory that if you where to do something over and over again it will become a trait that can be pasted on to your children. For example a giraffe stretches its neck so it is able to reach food higher up, the giraffe's neck becomes longer as a result of it's use, this allows the giraffe's offspring inherit its long neck. Darwinism is the theory created by Charles Robert…

unrealistic and therefore unbelievable; a world created in a mere six days where everything was considered “perfect” and “fully developed”. However we must consider it’s relevance in comparison to scientific facts and maybe we shouldn’t discard the theories and concepts which are hidden behind the biblical story of creation. For example, the story recognises that water came before land, like sea creatures came before land animals. This kind of information is scientifically proven and was unknown at…
