evet arkadaşlar burda darwini konuşuyoruz

@8 katılıyorum bende buna şöyle bir bakış açısı getirdim

Darwin sailed at age 22 in 1831 on the ship H.M.S. Beagle, a trip that would prove critical in leading Darwin to his understanding of evolution. Paramount was his visit to the many Galápagos Islands 600 miles off the west coast of South America.

Darwin identified 13 species of Finches among the Galápagos Islands that were primarily differentiated by beak size. In contrast, only one species of this bird existed on the mainland South America to the east. Darwin correctly concluded that the different beaks were adaptations to different diets available among the islands.

Darwin ultimately generalized the observation from the finches that any population consists of individuals that are all slightly different from one another. Furthermore, individual organisms having a phenotype characteristic providing an advantage in Darwin's Finchesstaying alive to successfully reproduce will pass their phenotype traits more frequently to the next generation. Over time and generations the traits providing reproductive advantage become more common within the population. Darwin called this process "descent with modification".

Darwin also correctly understood that the variability allowing adaptation already existed in the finch population, though its genetic (genotype) reason was not yet known by science at the time. Nature was NOT "producing" the variation within the finch populations - it already existed. Rather, nature "selected" from among the population variation the traits that better fostered survival and reproduction, a process known as "natural selection". The process guides evolution across the entire
