Evolution is the process by which all living thingshave developed from primitive organisms through changes occurring overbillions of years, a process that includes all animals and plants. Exactly howevolution occurs is still a matter of debate, but there are many differenttheories and that it occurs is a scientific fact. Biologists agree that all livingthings come through a long history of changes shaped by physical andchemical processes that are still taking place. It is possible that all organismscan be traced back to the origin of Life from one celled organims.The most direct proof of evolution is the science of Paleontology, orthe study of life in the past through fossil remains or impressions, usually inrock. Changes occur in living organisms that serve to increase theiradaptability, for survival and reproduction, in changing environments.Evolution apparently has no built-in direction purpose. A given kind oforganism may evolve only when it occurs in a variety of forms differing inhereditary traits, that are passed from parent to offspring. By chance, somevarieties prove to be ill adapted to their current environment and thusdisappear, whereas others prove to be adaptive, and their numbers increase.The elimination of the unfit, or the 'survival of the fittest,' is known asNatural Selection because it is nature that discards or favors aarticular being. Evolution takes place only when natural selectionoperates on apopulation of organisms containing diverse inheritable forms.HISTORYPierre Louis Moreau de Maupertuis (1698-1759) was the firsttopropose a general theory of evolution. He said that hereditary material,consisting of particles, was transmitted from parents to offspring. Hisopinionof the part played by natural selection had little influence on othernaturalists.Until the mid-19th century, naturalists believed that eachspecies wascreated separately, either through a supreme being or throughspontaneousgeneration the concept that organisms arose fully developed from soil orwater. Thework of the Swedish naturalist Carolus Linnaeus in advancing theclassifying ofbiological organisms focused attention on the close similarity betweencertainspecies. Speculation began as to the existence of a sort of bloodrelationshipbetween these species. These questions coupled with the emergingsciences ofgeology and paleontology gave rise to hypotheses that the life-forms ofthe dayevolved from earlier forms through a process of change. Extremelyimportant wasthe realization that different layers of rock represented different timeperiods andthat each layer had a distinctive set of fossils of life-forms that hadlived in the past.LamarckismJean Baptiste Lamarck was one of several theorists whoproposed anevolutionary theory based on the 'use and disuse' of organs. Lamarckstated thatan individual acquires traits during its lifetime and that...

(Dobzhanski, 1973) It was during his journey on board the Beagle that Darwin developed his theory of evolution. “On the Origin of Species” (Darwin, 1859) proposed two main principles: evolution really occurs and natural selection is its mechanism. This work published on 24th November 1859 traces a coherent portrait of life bringing together in an orderly manner an

Evidence of the theory of evolution

809 words - 3 pages There is abundant evidence that evolution occurs-that some species change over time, that other species diverge and become one or more new species, and that still other species become extinct. Darwin's theory was that evolution progresses through natural selection. The synthetic theory of evolution combines natural selection with the influence of genetics. These theories, together with the evidence for evolution from population genetics

Evidences of the Theory of Evolution

711 words - 3 pages . There is so much evidence that supports the theory of evolution. “Evidence could be provided from sources as different as ancient fossils and modern genetics labs.

More evidence comes from biogeography. Isolated islands are missing common species found on
