For those scientists who take it seriously, Darwinian evolution has functioned more as a philosophical belief system than as a testable scientific hypothesis. This quasi-religious function of the theory is, I think, what lies behind many of the extreme statements that you have doubtless encountered from some scientists opposing any critical analysis of neo-Darwinism in the classroom. It is also why many scientists make public statements about the theory that they would not defend privately to other scientists like me. ↗

Our brains contain one hundred billion nerve cells (neurons). Each neuron makes links with ten thousand other neurons to form an incredible three dimensional grid. This grid therefore contains a thousand trillion connections - that's 1,000,000,000,000,000 (a quadrillion). It's hard to imagine this, so let's visualise each connection as a disc that's 1mm thick. Stack up the quadrillion discs on top of each other and they will reach the sun (which is ninety-three million miles from the earth) and back, three times over. ↗
Darwin, with his Origin of Species, his theories about Natural Selection, the Survival of the Fittest, and the influence of environment, shed a flood of light upon the great problems of plant and animal life. These things had been guessed, prophesied, asserted, hinted by many others, but Darwin, with infinite patience, with perfect care and candor, found the facts, fulfilled the prophecies, and demonstrated the truth of the guesses, hints and assertions. He was, in my judgment, the keenest observer, the best judge of the meaning and value of a fact, the greatest Naturalist the world has produced. The theological view began to look small and mean. Spencer gave his theory of evolution and sustained it by countless facts. He stood at a great height, and with the eyes of a philosopher, a profound thinker, surveyed the world. He has influenced the thought of the wisest. Theology looked more absurd than ever. Huxley entered the lists for Darwin. No man ever had a sharper sword -- a better shield. He challenged the world. The great theologians and the small scientists -- those who had more courage than sense, accepted the challenge. Their poor bodies were carried away by their friends. Huxley had intelligence, industry, genius, and the courage to express his thought. He was absolutely loyal to what he thought was truth. Without prejudice and without fear, he followed the footsteps of life from the lowest to the highest forms. Theology looked smaller still. Haeckel began at the simplest cell, went from change to change -- from form to form -- followed the line of development, the path of life, until he reached the human race. It was all natural. There had been no interference from without. I read the works of these great men -- of many others – and became convinced that they were right, and that all the theologians -- all the believers in "special creation" were absolutely wrong. The Garden of Eden faded away, Adam and Eve fell back to dust, the snake crawled into the grass, and Jehovah became a miserable myth. ↗
Genetics might be adequate for explaining microevolution, but microevolutionary changes in gene frequency were not seen as able to turn a reptile into a mammal or to convert a fish into an amphibian. Microevolution looks at adaptations that concern the survival of the fittest, not the arrival of the fittest... The origin of species — Darwin’s problem — remains unsolved. ↗
