What a book! Charles Darwin's theory of natural selection has been called "the best idea that anyone ever had", and I am tempted to agree. Darwin's great insight was that in the same way that humans breed plants and animals with certain characteristics, nature "breeds" itself, and creates variation. He notes that all creatures reproduce at a rate faster than the earth can support them, and so many of them must die. He realized that it is not random which individuals die and which ones live. Rather, those that are best fitted for their environment are most likely to survive. Over time, the attributes that allowed them to survive will be passed on throughout the population, and will supplant the old population. Darwin's realized that these small, gradual changes were strong enough to create all of the diversity around us, over time. He uses embryology, the fossil record, migration patterns, classification patterns, and the existence of rudimentary organs as evidence for his beautiful theory. Since then, we have found more and more evidence for the actuality of evolution as "the origin of species". I highly recommend this book. Some of it is fairly dense and repetitive, but it is wonderful. It provides a new way to see the world, and as Darwin says in his concluding paragraph: "There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."
