Which nobody can deny. Darwin received immediate support from that energetic churchman, naturalist and novelist Charles Kingsley, and later an admiring letter from Karl Marx. Bestseller Origin was a bestseller. The publisher John Murray ran off 1, copies and took orders for 1, even before the publication day, including for a circulating library.

But no consensus exists as to the source of this revolutionary change. Indeed, this limitation is true for all the extraordinary theories of modern physics, which have had little impact on the way the average person apprehends the world.
The situation differs dramatically with regard to concepts in biology. Many biological ideas proposed during the past years stood in stark conflict with what everybody assumed to be true. The acceptance of these ideas required an ideological revolution. Although I will be focusing on this last domain, for the sake of completeness I will put forth a short overview of his contributions—particularly as they inform his later ideas—to the first two areas.
A Secular View of Life Darwin founded a new branch of life science, evolutionary biology. Four of his contributions to evolutionary biology are especially important, as they held considerable sway beyond that discipline. The first is the nonconstancy of species, or the modern conception of evolution itself.
The second is the notion of branching evolution, implying the common descent of all species of living things on earth from a single unique origin.
Darwin further noted that evolution must be gradual, with no major breaks or discontinuities. Finally, he reasoned that the mechanism of evolution was natural selection. Despite the passing of a century before this new branch of philosophy fully developed, its eventual form is based on Darwinian concepts.
For example, Darwin introduced historicity into science. Evolutionary biology, in contrast with physics and chemistry, is a historical science—the evolutionist attempts to explain events and processes that have already taken place. Laws and experiments are inappropriate techniques for the explication of such events and processes.
Instead one constructs a historical narrative, consisting of a tentative reconstruction of the particular scenario that led to the events one is trying to explain. For example, three different scenarios have been proposed for the sudden extinction of the dinosaurs at the end of the Cretaceous: The first two narratives were ultimately refuted by evidence incompatible with them.
All the known facts, however, fit the Alvarez theory, which is now widely accepted. The testing of historical narratives implies that the wide gap between science and the humanities that so troubled physicist C. Snow is actually nonexistent—by virtue of its methodology and its acceptance of the time factor that makes change possible, evolutionary biology serves as a bridge.
The discovery of natural selection, by Darwin and Alfred Russel Wallace, must itself be counted as an extraordinary philosophical advance.
The principle remained unknown throughout the more than 2,year history of philosophy ranging from the Greeks to Hume, Kant and the Victorian era.
The concept of natural selection had remarkable power for explaining directional and adaptive changes. Its nature is simplicity itself. It is not a force like the forces described in the laws of physics; its mechanism is simply the elimination of inferior individuals.
In fact, nothing is predetermined. Furthermore, the objective of selection even may change from one generation to the next, as environmental circumstances vary.
A diverse population is a necessity for the proper working of natural selection. Because of the importance of variation, natural selection should be considered a two-step process: This latter step is directional.
By adopting natural selection, Darwin settled the several-thousandyear- old argument among philosophers over chance or necessity. Change on the earth is the result of both, the first step being dominated by randomness, the second by necessity. Darwin was a holist: The geneticists, almost from on, in a rather reductionist spirit preferred to consider the gene the target of evolution.
In the past 25 years, however, they have largely returned to the Darwinian view that the individual is the principal target.
For 80 years afterbitter controversy raged as to which of four competing evolutionary theories was valid. Lamarckian evolution relied on the inheritance of acquired characteristics.
Darwinism is now almost unanimously accepted by knowledgeable evolutionists. In addition, it has become the basic component of the new philosophy of biology.Watch video · Following a lifetime of devout research, Charles Darwin died at his family home, Down House, in London, on April 19, He was buried at Westminster Abbey.
