Who knows not, the theory of "Survival of the fittest" ?
in the same breath is often the name "Charles Darwin" and the term "Darwin's finches." Most will probably know too, that Charles Darwin is the founder of evolution theory and that the finches of the Galapagos Islands one of the crucial discoveries were to work at a theory of evolution.
The theory of evolution has undergone an evolution!
Against Darwin - a puzzle full of knowledge and how easy it the naturalists have made
But out of the blue and only the finches he did not come to this realization. Even before Darwin, many findings were already present. But initially it was all still had a hodgepodge of nothing but puzzle pieces that are only brought even.

geologists noted early on that the planet has far is so rigid as reported in Genesis. And yet, the first theories from today's point have been rather sobering floods and other disasters were the Universal Declaration for any natural species on Earth.
Why is the Sahara desert? - Because it has long ago a flood washed the plants. And what about the huge stone blocks have the heart to signify in the landscape? Sure, that are legacies of a flood.
But what should have been expected at that time? Finally, the creation of an unrivaled history theory and no one dared to doubt her.
Lamarck and the long necks of giraffes.
And but it seems strange that you can not soon came upon the idea that there is real relationship between the species and, finally, people had already modified animals - think of the breeding of farm animals. provides one of the first theories Lamarck, who recognized that animals change to adapt to the environment. Using the example of why giraffes have such long necks, he imagined that the giraffe its neck used very often and the neck extended. The characteristic of the long neck was eventually transferred to the next generation.
Darwin
Darwin's theory sounds now but much more convincing: According to his theory of evolution had been given by mutation once a giraffe a long neck. This long neck is considered contrary to their short-necked fellows as an advantage: the long-necked giraffe was more comfortable with the coveted foliage of the trees and got more cousins.

An evolution the evolution theory?
But not only the short-necked giraffe of the same species have become extinct. Also some parts of Darwin's theory of evolution are. Those who believe, then, that his whole theory from the beginning was absolutely perfect and really has made a mistake.
He had such a strange idea of how the properties are transferred to the next generation. He imagined that FORM AN each body part small "gemmules" who gathered in the sexual organs and in forming a new body of father and mother mix (why would a man seen in most cases both parents, a little similar!)! ?
But this theory should indeed turn out to be wrong at least according to Mendel, just as Darwin's theory, that the evolution of a development towards increasingly better adapted animals / plants is. Evolution does not produce perfect beings and it is doubtful that we humans are really adapted better than cockroaches, nude mulch or even bacteria.
Other parts of the theory of evolution have evolved, however. For example
are organisms over time has not always according to their differentiation on her own. "symbiosis" is the keyword here. Once joined together protozoa to form an organism with which it could be easier to survive. Even we live in a symbiosis - a symbiotic relationship with millions of bacteria, even though we constantly want to get rid of Zillit Bang and Sakrohtan .
Again the thing with the flood. In order to appease
but at least in the last paragraph, the proponents of the flood theory: How wrong were our researchers do not yet! In the meantime, it is clear that disasters and environmental changes have intervened in the evolution. Even Lamarck's theory is to be true in some cases, even if she had on the evolution of no significant impact.
