In 1842 he wrote what he called the "pencil sketch of my species theory", and in 1844 he wrote a fuller and more polished version, which he wanted published in the event of his death. These two essays are reproduced in this excellent book. They show that all the key ideas that Darwin made public in 1859 in "On the Origin of Species" had already been developed by him much earlier.
Anyone who is tempted to take seriously the ridiculous conspiracy theory which claims that Darwin stole the theory of natural selection from Alfred Russel Wallace should read this book. Wallace certainly deserves credit for independently coming up with the same idea, but Wallace himself was always happy to play second fiddle to Darwin. For example, in 1908 Wallace made a speech to the Linnaean Society in which he explicitly defended Darwin's priority, pointing out that "...the idea occurred to Darwin in October 1838, nearly twenty years earlier than to myself (in February 1858); and that during the whole of that twenty years he had been laboriously collecting evidence..."
Darwin seems to have delayed publishing for two reasons. Firstly, he wanted to establish himself as a serious scientist and to accumulate a mass of evidence in support of the theory before going into print. And secondly, he was nervous of the trouble it would stir up, especially in the pre-1850 period when social upheavals and Chartist radicals were associated with the idea of evolution.
This book also shows that an error that Darwin made can also be traced back to these two early essays. Despite coming up with natural selection as the mechanism for evolution, Darwin mistakenly gave a subsidiary role to the Lamarckian idea of the inheritance of acquired characteristics. There are a few Lamarckian lapses in "On the Origin of Species"; and "The Expression of Emotion in Man and Animals", for example, is full of them.
Here in the 1844 essay Darwin writes: "There is reason to believe that when long exercise has given to certain muscles great development, or disuse has lessened them, that such development is also inherited."
But why should we expect Darwin's thinking to be perfect? Nothing was known of modern genetics at that time. Darwin is one of my heroes; but he is a flawed hero, and that makes him all the more appealing.
Finally, we can even trace back to the 1842 sketch, almost word-for-word, the well-known ending of "On the Origin of Species". The 1842 version is:
"There is a simple grandeur in the view of life with its powers of growth, assimilation and reproduction, being originally breathed into matter under one or a few forms, and that whilst this our planet has gone circling on according to fixed laws, and land and water, in a cycle of change, have gone on replacing each other, that from so simple an origin, through the process of gradual selection of infinitesimal changes, endless forms most beautiful and most wonderful have been evolved."
Leider gibt es immer noch viele Staaten auf der Welt, welche sich noch nicht mit der Darwin Realität angefreundet haben.
Granted, I know that Darwin lived in an era before micro- and molecular biology came into their prime, but he still cannot explain how extremely different species could have possibly descended from one ancestor. He talks about the incremental nature of natural selection, but then why do we not have any species which are incrementally different than others?
He fails to see that molecules--and DNA--simply CAN'T just "change" a little bit. This is called a mutation and is always destructive to the organism.
However, this book is good if you want to gain an understanding of what Darwin thought, as it is his own words. I just can't endorse it because it is so logically flawed in every way.
