Charles Darwin's Theory Of Natural Selection

Charles Darwin devoted his work and research to the Theory of Evolution. From his work, his purpose was to understand the increase and decrease in certain alleles within a population, and this is what he called natural selection. This Theory of Evolution can be considered to be the most credible due to its ample evidence and feasibility. An example of natural selection can be seen within certain types of birds. If a seed eating bird were to have a small bill, it would most likely only be able to eat the smaller seeds in the ecosystem it is in. The larger billed birds would have more of an advantage of obtaining food if a drought were to occur and erased all of the smaller seeded plants within the region. Overall, birds can also be noticed to be disadvantaged in the aspect of adaptation to winter weather. Most animals that live within Iowa are used to Iowa weather, but birds Migrate to the south by flying. Birds are still an excellent example to describe mate choice. For

This could be from mating calls that are instinctual within animals, to learning a language within humans. It should be noted that Darwin’s theory also includes this, as well as the knowledge of variation and “Survival of the Fittest.” Variation correlates with the phenotype of each individual within the species. Phenotypes derive from the genetics of the parents. Individuals with more physically appealing looks within the peacock species are more likely to acquire a mate and reproduce. If a species were to conceive and the phenotype or alles had been deleted or changed, this is called Mutation. With further explanation, when mutation happens in wild animals, death can typically occur. Survival of the Fittests i the theory that only the strongest survive. This theory is not limited to specific species, nor is it limited within species. This can occur at any time with multiple different
