It is impossible to pass by this book if you are interested in evolutionary biology. And although science has moved far ahead since those distant days, and some of the author’s thoughts already seem naive, it is interesting to learn where thinking in this field began.
What The Book Is About
Darwin builds the argument methodically, almost legally. First comes artificial selection: how pigeon breeders and livestock breeders, over several generations, change breeds beyond recognition. Then comes natural selection: if humans can change animals like this, why can nature not do the same thing, only more slowly and more effectively?
The book is full of examples from botany, entomology, and paleontology. Darwin is above all a naturalist, and his strength is in observations: orchids adapted to particular pollinating insects; rudimentary organs, useless to their owner but understandable as an inheritance from ancestors; the geographical distribution of species on islands.
What Darwin Did Not Know
Genetics. Darwin did not understand the mechanism of inheritance — Mendel’s works were published in 1866 but remained unknown until the 1900s. This created a serious problem: if traits are “blended” during crossing, how are useful variations preserved? The answer came only with the synthetic theory of evolution in the 20th century.
Is It Worth Reading Today?
The book is written in a heavy Victorian style. The theses are repeated with enviable constancy — it is noticeable that Darwin is arguing with an imaginary opponent, anticipating objections. For the modern reader this is tiring: we already accept evolution as a fact.
But as a historical document, On the Origin of Species is priceless. This is the moment when biology stopped being a catalog of creations and became a science of processes. Darwin did not just propose a theory — he showed how to build a scientific argument on the basis of observations.
For an introduction to modern evolutionary biology, it is better to start with Dawkins (The Selfish Gene, The Blind Watchmaker). But if you want to understand how revolutionary ideas are born — read the original.
