Hello, I am looking for someone to write an essay on Discuss the origin and diversity of life.Darwin s evolution theory.how organisms evolved fron the simplest prokaryotes to the more complex eukaryoteswhat structures,functions and adaptions they developed during the course of evolution. It needs to be at least 3500 words.
However, this concept required proof of how the innumerable species inhabiting this world have been modified to acquire their particular shape and adaptation to natural habitat.
Charles Darwin, in his Origin of Species (1859) wrote ‘probably all of the organic beings which have ever lived on this Earth have descended from some primordial form1’ Much focus was given to the fact that large amount of hereditary modification existed, a
nd only those modifications or features selected by living beings thrived. Darwin’s study focused heavily on the variations that existed among various living organisms and the phenomenon of natural selection responsible for the extinction and elimination of less improved forms of life leading to divergence of character. He also strongly backed the fact that species are not immutable. and that, the way organisms belonging to one species are the descendants of that species, similarly those belonging to the same genera are lineal descendants of some other and generally extinct species (Darwin, C & Marcus, H. 30). Darwin drew many of his observations from the work of Linnaeus, Cuvier, Hutton, Lyell, Malthus and Lamarck. however, his own observations had formed the basis for his postulations.
The basis for Darwin’s philosophy of evolution can be traced back to his voyages of the HMS Beagle in the 1830s during which he observed that the living organisms had many similarities with that of few fossils. Another observation was the diversity of life on the Galapagos Islands, such as a myriad of birds and insects. This was the basis for him to believe that the Earth was continually changing. same happened with living organisms, and also that they were a product of the earlier life-forms. Through his observations, Darwin proposed the two mechanisms associated with evolution, natural selection and variation that
