'Darwin’s Theory of Evolution & Natural Selection Essay\r'

'Charles Robert Darwin was born on 12 February 1809 in Shrewsbury, Shropshire into a wealthy family. Darwin himself initially planned to fit a medical career, and studied at Edinburgh University besides later switched to divinity at Cambridge. In 1831, he joined a five year scientific expedition on the survey ship HMS Beagle. This is where he came up with his theory of growing. During his voyage on the Beagle, Darwin put evidence that challenged traditional belief that species are unchanging. During this, he read Charles Lyell’s daybook Principles of Geology. As Darwin began see many sites, he began to see things that he vox populi could be explained only by a bidding of gradual change. He established the plants and animals on the Galapagos Islands resembled those in South the States. 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 continued his studies, but did non report his ideas of evolution until many years later.\r\nThe severalise to Darwin’s thinking rough how evolution takes place was an essay written in 1798 by doubting Thomas Malthus. Malthus suggested that human populations do not grow unbridled because death caused by disease, war, and famine slows population growth. Darwin realized that his hypothesis can apply to all species. Considering Malthus’s view and his own observations and experience in gentility domestic animals, Darwin made a key association. A process in nature in which organisms possessing plastered genotypic characteristics that make them better adjusted to an surroundings tend to start, reproduce, increase in number or frequency, and therefore, are able to transmit and perpetuate their indwelling genotypic qualities to succeeding generations.\r\nHe call this inhering selection. In 1844, Darwin finally wrote down all these ideas about evolution and natural se lection in and earlyish outline that he showed to few scientists. He inflexible to publish it after being contacted by Alfred Russel Wallace. His book On the Origin of Species by Means of born(p) Selection appeared in November of 1859. Darwin’s theory of evolution and natural selection were based on quartet major points. 1) Inherited variation exists within the genes of all(prenominal) population or species. 2) In a circumstance environment, some individuals are better suited to survive and have more offspring.\r\n'
