The term “evolution” conjures the image of a single-celled amoeba’s gradual progression and eventual formation into a multicellular organism. This process occurs over a period of time when organisms undergo a variety of hurdles which may alter their biological and chemical structures to differentiate them from another species. Charles Darwin, the father of evolutionary theory pioneered the idea that life had a common origin from which species arose from. In one of his famous works, “On the Origin of Species,” Darwin states that the mechanism that propelled these changes originate from the survival of the fittest (where the most successful species live long enough to contribute to the gene pool) (Darwin 144). However the theory was later changed

Darwin’s observation of the different breeds of domestic pigeon showed that the birds possess varying beak shapes, wing sizes, and performed different functions. He reasoned that although London’s domestic pigeons had originated from the Rock Pigeon, the new breeds were physically recognizable but were functionally different from each other as they were bred for a certain desirable characteristic (Darwin 55-56). Although the pigeons in this scenario were selectively bred for the desirable physical traits that were desired, this factor successfully depicts Darwin’s theory of natural selection. Through sexual reproduction of certain heritable traits, a specie’s diversity is dependent on the members being able to successfully pass on their genes. In context, these physical changes would not be abrupt as selective breeding as the events are more random in nature due to genetic shuffling from copulation. Sexual selection in a natural environment is not specific and picks certain traits that are highly advantageous to the area of habitation. The process of sexual selection would eventually alter the progeny and completely change the specie’s composition over many generations. According to these results, Darwin reasoned that given a substantial amount of time, sexual selection would eventually lead to speciation through the marginal divide of gene acquired physical …show more content…
Science is an ongoing process where change occurs with new findings however the theory has already been confirmed by further research. However the recent addition involving genetics is still an ongoing process in explaining such interaction between heritability. Regardless of the physical or genetic implications of the theory, natural selection was the first attempt at forming concepts to explain the potential causes of speciation. The theory ultimately states that evolution is a slow and gradual process where organisms adapt to their environment. Thus natural selection is composed of many individual components as observations reveal the many factors affecting this ongoing process. The entire procedure shows how random evolution is and that the deciding factors ultimately reside in each individual organism’s success at reproduction. And if given the right conditions and differences, the event where a new species created is possible over
