Darwin argued that the beak size and shape was related to their food source.

Since evolution follows "the survival of the fittest", the finches with the beaks better suited to the available food on the island would out compete other finches.

This explains why finches on different islands had different beaks, because the islands had different food sources.

Actually he didn't make a statement on this matter. The super myth is that Darwin's theory of evolution crystallized when he saw the different beaks on finches in the Galapagos Island based on their beak shapes. He didn't pay much attention to them and mis labeled many of his samples of the birds. His theory came from years of studies of creatures from small invertebrates, to plankton, to insects and then the collection of large extinct mammal fossils. It was paired with a knowledge of geology and how the earth has evolved as an environment upon which every living thing has existed upon.

What were Charles Darwin's other jobs?

Briefly(!), Darwin's life was dominated by two events; his voyage around the world on the Beagle and the publication of the Origin of the Species. During the voyage on the Beagle, Darwin was able to see for himself the effects of small changes over long periods of time. For example, there was an earthquake whilst he was in South America and the land rose by a few feet. He also found fossil seashells on the peaks of the Andes. He realised that over millions of years with thousands of earthquakes, what was once under the sea will, eventually become mountains. His key idea was to apply this kind of insight to how life developed over long periods of time. This was made clear for him during his visit to the Galapados islands which, he realised, were formed relatively recently and that life arrived on "rafts" of vegetation from the Amazon or by air. Limited environments, such as islands, have produced giants (as with the tortoises), flightless birds, marine lizards and specialised adaptions as with Darwin's finches' beaks. It was asking the question, "How did a single finch species become several specialised species?" that led to the theory of evolution. The theory was published in The Origin of the Species. The book is a beautifully written, well argued logical argument with a wealth of evidence that could be tested by other workers. The book was a Victorian bestseller and Darwin became one of the most well-known scientists of his age. Darwin was not formally trained in Natural History; his degree was in theology. So to prove his credentials he spent a number of years studying whelks, become an authority on them. He also became an expert on earthworms, explaining how soil was moved by them.


What do people say about Charles Darwin?

In my personal opinion, Darwin was a genius far ahead of his time. He helped people better understand the world, and that is admirable. Don't listen to the religious loonies who put him down because he threatens their beliefs. Creationists think that Darwin was an atheist trying to prove that life happened on its own, and that men descended from monkeys. Darwin did not actually believe it, but atheists who do believe it probably see Darwin in the same way as the creationists, although they are more kindly disposed toward him. I agree with the above answer which is a balanced view of Charles Darwin.


Why do you now accept that Darwin rather than lamarck was correct?

Introduction: On the Philosophy & Metaphysics of Charles Darwin's Theory of EvolutionFor thousands of years many philosophers had argued that life must have been created by a supernatural being / creator / God due to the incredible complexity of Nature (in particular, we humans and our minds). Thus it is remarkable that Charles Darwin (and others) were able to explain our existence by means of Evolution from Natural Selection - which is very obvious once understood.Below you will find a brief summary of Charles Darwin's Theory of Evolution and some interesting quotes from Darwin on Evolution, Natural Selection, Science, Humanity, God and Religion.When thinking about evolution, it is important to take a further step and ask, 'What is evolving?' As this website explains, there is a simple and obvious explanation of what exists and thus how we can understand the metaphysical foundations of Evolution. See Evolution-Metaphysics webpage.We hope you enjoy the following quotes and browsing around this website. We have a wonderful collection of knowledge from many of the greatest minds of human history - and most importantly can provide a simple sensible explanation for most of them!Cheers,Geoff Haselhurst, Karene HowieAlthough I am fully convinced of the truth of the views given in this volume I by no means expect to convince experienced naturalists whose minds are stocked with a multitude of facts all viewed, during a long course of years, from a point of view directly opposite to mine. But I look with confidence to the future to young and rising naturalists, who will be able to view both sides of the question with impartiality. (Charles Darwin)

What oppositions did Darwin's theory have?

It has been argued from the earliest publication of Darwin's theory of evolution that since the bible describes the creation of species as an instantaneous process, performed by God, rather than an evolutionary process resulting from natural selection, Darwin's theory is religiously unacceptable.


What is overproduction?

Overproduction is a driving force in natural selection, as it can lead to adaptation and variations in a species. Darwin argued that all species overproduce, since they have more offspring than can realistically reach reproductive age, based on the resources available. -Google More offspring are produced than can survive. -gradpoint/novanet

How might Darwin's observation that species change over time be seen as unorthodox to most of his contemporaries?

Because the majority of people in the world at that time believed in intelligent design i.e.; God made it.When Darwin said that life was EVOLVING and changing itself,the idea was a revolution in thinking about the ideas of life and religion that is still argued about to this day.
