Explanation:
This is a shame, not only because there is much more to Darwin’s theory than the familiar principles of mutation, variation, natural selection, and evolution that have entered popular knowledge as Darwinian buzzwords. The book also gives unique insight into the intellectual milieu in which he developed his theory and his struggles to convince his peers of its veracity.
Indeed in this age of the counter-factual and pseudo-factual, acquaintance with the foundations of our scientific tradition — and insights into the struggles of their creation — seems a matter of some urgency.
In the introduction alone, we learn that Darwin first conceived of his theory when travelling the world as a naturalist on board HMS Beagle (1831-6), that he had kept collecting data in support of it ever since, that he even wrote a rough draft (he calls it “a sketch of the conclusions”) many years earlier, and that he was prompted to publish it (20 years later) only because his contemporary Alfred Russel Wallace had recently sent him a “memoir” reaching a similar conclusion.
The core of the theory, as laid out in the first few chapters of the book, is quickly explained. Plants and animals produce more individuals than nature can sustain in each generation. These individuals vary in looks and in physical and behavioural characteristics, and they are able to pass on this variation to the next generation. Those individuals better suited to their environment have an advantage and are in turn more likely to survive to give their features to future generations.
Yet the bare bones of his theory of evolution are only part of what shapes this book. Darwin also communicates the obstacles he had to overcome to ensure its success and to turn it into what it became: a foundational text of the biological sciences that influenced all sorts of other disciplines, including anthropology, religious studies, and the Classics.
