Natural Selection. Darwin called this mechanism of change natural selection. Natural selection, Darwin argued, was an inevitable outcome of three principles that operated in nature. First, the characteristics of organisms are inherited, or passed from parent to offspring.

11 de feb. de 2015 · Darwin’s finches, inhabiting the Galápagos archipelago and Cocos Island, constitute an iconic model for studies of speciation and adaptive evolution. Here we report the results of whole-genome ...
Darwin’s finches from the Galápagos archipelago have historic importance in the field of evolutionary biology as they provided some of the fundamental insights into processes of natural selection and adaptive radiation.
1 de oct. de 2003 · A long-term study of finch populations on the island of Daphne Major has revealed that evolution occurs by natural selection when the finches' food supply changes during droughts.
21 de abr. de 2016 · Researchers are pinpointing the genes that lie behind the varied beaks of Darwin’s finches – the iconic birds whose facial variations have become a classic example of Charles Darwin's theory of...
4 de abr. de 2010 · One of the classic examples of adaptive radiation under natural selection is the evolution of 15 closely related species of Darwin's finches (Passeriformes), whose primary diversity lies in the size and shape of their beaks.
Darwin identified a special case of natural selection that he called sexual selection. Sexual selection affects an individual’s ability to mate and thus produce offspring, and it leads to the evolution of dramatic traits that often appear maladaptive in terms of survival but persist because they give their owners greater reproductive success.
