Charles Darwin was a naturalist who wrote On The Origin of Species, it was one long argument against creationism.
Lamarck was the first man whose conclusions on the subject excited much attention. This justly celebrated naturalist first published his views in 1801; he much enlarged them in 1809 in his "Philosophie Zoologique", and subsequently, 1815, in the Introduction to his "Hist. Nat. des Animaux sans Vertebres". In these works he up holds the doctrine that all species, including man, are descended from other species. He first did the eminent service of arousing attention to the probability of all change in the organic, as well as in the inorganic world, being the result of law, and not of miraculous interposition. (Charles Darwin, On the Origin of the Species)
It is an exclusively naturalistic worldview where miracles are categorically rejected. Darwinism is often referred to as the theory of evolution, but there is no theory of evolution. Evolution is a phenomenon in nature, the so called theory of evolution is the a priori (without prior) assumption of universal common ancestry by exclusively nationalistic causes going all the way back to and including the Big Bang.
At Cambridge studied Medical Science but didn't want to be a doctor, he said he couldn't stand to see children suffer. He switched to a ministry undergraduate degree which was very common at the time, much like a liberal arts degree. This was a man who knew so much about how favorable traits were passed on the future generations that he married his own cousin, as his grandfather had done. One of the biggest problems with inbreeding is you start to get bottlenecks in the gene pool, one of the first things to be compromised is the immune system. His daughter Anne died of scarlet fever, most biographers will tell you her death colors the book.
Darwin was known to be congenial, while in Cambridge he met a professor from Brazil who was a taxonomist. Stories about the rain forests fascinated young Charles and eventually he would set sail aboard the Beagle. The crew called him ole flycatcher and the kindly old philosopher. As they set sail Darwin was reading the geologist Lyell, who proposed a uniformatarian view of geology, layers added one after another over successive centuries. He applied this and the natural history philosophy of Larmark and on other key element.
Malthus’ most famous work, which he published in 1798, was
An Essay on the Principle of Population as it affects the Future Improvement of Society. In it, Malthus raised doubts about whether a nation could ever reach a point where laws would no longer be required, and in which everyone lived prosperously and harmoniously. There was, he argued, a built-in agony to human existence, in that the growth of a population will always outrun its ability to feed itself. If every couple raised four children, the population could easily double in twenty-five years, and from then on, it would keep doubling. It would rise not arithmetically—by factors of three, four, five, and so on—but geometrically—by factors of four, eight, and sixteen.
Between 1800 and 2000 the human population increased about six-fold. Has the food supply kept pace? Will there be enough food to support the projected population of 9.2 billion in 2050? (

Don't believe for a minute this is just about how someone wants to interpret Scripture. This thing called Darwinism is a political and legal philosophy, espoused by people who are scared to death of an apocalyptic mass die off, due to overpopulation. The gay rights agenda has nothing to do with privacy or due process, it's the Ivy League types micromanaging people to stem the tide of over population.
Darwinism is more then one thing and it has little to do with evolution, it's about population control.
