To a certain extent it suffers from the Hamlet problem--it's full of clichés! Or what are now clichés, but which Darwin was the first to pen. Natural selection, variation, the struggle for existence, survival of the fittest: it's all in here.
Darwin's friend and "bulldog" T. H. Huxley said upon reading the Origin, "How extremely stupid of me not to have thought of that." Alfred Russel Wallace had thought of the same theory of evolution Darwin did, but it was Darwin who gathered the mass of supporting evidence--on domestic animals and plants, on variability, on sexual selection, on dispersal--that swept most scientists before it. It's hardly necessary to mention that the book is still controversial: Darwin's remark in his conclusion that "Light will be thrown on the origin of man and his history" is surely the pinnacle of British understatement. --Mary Ellen Curtin, Amazon.com
Some claim that Darwin admitted of the possibility of Lamarkian mechanisms. They have not read the original. Darwin knew nothing of the molecular basis of genetics, but knew that natural selection did not need a Lamarkian mechanism. He simply did not rule it out, although he found it improbable. Everything that is stated in this great classic is as true today as it was at the time of first publication.
It is also said that Charles Darwin was a lesser intellectual when compared to most other great names of science; that he was a plodder, a naturalist, a sort of gentleman stamp collector who pressed flowers into his books and barely a scientist in the contemporary sense. This is nonsense. Darwin was one of the giants of rigorous systematic thinking; the kind of rigorous thinking and critical attitude that asks the right questions and provides the capacity to answer them. Let me buttress this claim with one example.
At the end of chapter six Darwin noted that the theory of natural selection could not account for structures or behaviors found in one species that exist solely for the benefit of another unrelated species. In setting out the theoretical terms for the refutation of the theory in this way, he anticipated Karl Popper, that analytical non-nonsense philosopher of science, by more than a century.
I recommend you read this book with an attentive curious analytical mind. You will find yourself walking in the footsteps of an intellectual giant.
I would also like to say that maybe this book might not have all the up-to-date scientific information in it (after all it was published in the 1850's) and yes it is true we know allot more about evolution than Darwin did but for the average person like my self who has little education the Biology field I can say I learnt allot about evolution, ideas of the time and of Darwin himself.
I urge everyone to read this book whether Atheist, Christian, Buddhist or anything else because this book is not the devilish attack on religion it has been distorted to be over the years but simply an ordinary guy who liked to watch his pigeons and flowers grow and change between generations. He then came up with the idea that creatures and plants evolved between generations to suit there environment and were not all created by god in there current forms. I also believe Darwin to be a very tasteful writer who took care to upset as few people as possible and wrote in a very humble way in fact he dedicates a whole chapter to the problems of his theory.
A great read what ever you believe buy this book and make your own mind up about evolution!!
