Darwin’s Theory of Evolution & Natural Selection Essay

Charles Robert Darwin was born on 12 February 1809 in Shrewsbury, Shropshire into a wealthy family. Darwin himself initially planned to follow a medical career, and analyse at Edinburgh University but ulterior switched to divinity at Cambridge. In 1831, he joined a quin year scientific expedition on the survey ship HMS Beagle. This is where he came up with his theory of evolution. During his voyage on the Beagle, Darwin found evidence that challenged traditional belief that species are unchanging. During this, he read Charles Lyells disk Principles of Geology. As Darwin began visiting many places, he began to see things that he thought could be explained only by a process of gradual change. He realized the plants and animals on the Galapagos Islands resembled those in South America. He later suggested that the animals migrated to the Islands from South America and changed after they arrived. He later called this change evolution. When he returned from his voyage he act his stud ies, but did non report his ideas of evolution until many years later.The key to Darwins thinking to the highest degree how evolution takes place was an essay written in 1798 by Thomas Malthus. Malthus suggested that human populations do not grow unchecked because death caused by disease, war, and famine slows population growth. Darwin realized that his hypothesis can slang to all species. Considering Malthuss view and his own observations and experience in breeding domestic animals, Darwin made a key association. A process in nature in which organisms possessing certain genotypic characteristics that make them give out adjusted to an environment tend to survive, reproduce, increase in number or frequency, and therefore, are able to mail and perpetuate their essential genotypic qualities to succeeding generations.He call this natural selection. In 1844, Darwin finally wrote subject all these ideas about evolution and natural selection in and early outline that he showed to a couple of(prenominal) scientists. He decided to publish it after being contacted by Alfred Russel Wallace. His book On the Origin of Species by Means of Natural Selection appeared in November of 1859. Darwins theory of evolution and natural selection were found on four major points. 1) Inherited variation exists within the genes of every population or species. 2) In a particular environment, some individuals are better suited to survive and have more offspring.
